is there difference between debug and release reference path while compiling? - silverlight

I am building a SL3 + RIA application in VS2008. When compiled the application in debug mode it compiles fine with out any error, but when I compile the same application with out any code change in release mode I get an error
'The type of namespace name 'BusyIndicator' does not exist in the namespace 'System.Windows.Controls' (are you missing an assembly reference).
All the errors are coming from the generated code name.g.cs
Just curious anyone run into this problem.

This still happens when you do a Clean and/or Rebuild?
I've seen odd issues with the *.g.cs files, try just adjusting something immaterial in the xaml to force the re-creation of the *.g.cs file.

Compiling specific apache module in VS2010

Over the last few days I've been tinkering with mod_pLua on Windows (https://sourceforge.net/projects/modplua/ or https://github.com/Humbedooh/mod_pLua).
The pre-built Windows binary works a treat, except it doesn't seem to have been compiled with mod_dbd support for database connectivity. The documentation suggests that to enable this feature you must compile with a certain tag, so I've been trying to compile the module in VS2010 - hoping that I'll be able to get mod_dbd support working at some point - but I've run in to a snag. It just will not compile.
What I've done so far:
Included apache/include and apache/lib, which got rid of a lot of
errors
Included lauxlib.h, lua.h, luaconf.h and lualib.h from Lua 5.2, which got rid of a lot of errors
Compiled a .lib file from Lua 5.2 sources and included it, which fixed a few errors
The errors I'm getting at the moment are:
error LNK2019: unresolved external symbol _luaL_openlib referenced in function _lua_dbopen C:\Users\Michael\Desktop\Projects\C\mod_plua\mod_plua.obj
And a plethora like this:
IntelliSense: a value of type "const char ()(cmd_parms *cmd, void *cfg, const char *arg)" cannot be used to initialize an entity of type "cmd_func" c:\users\michael\desktop\projects\c\mod_plua\mod_plua.h 394 5
As I'm not a C/C++ native, I only have a vague idea of what's wrong, and have likely done something wrong in my attempts to fix the issue. If someone could guide me in the right direction (or better yet, write a little instructional on how to compile the module from start to finish) I would be so happy.
I've uploaded my VS2010 project files and source here: https://dl.dropboxusercontent.com/u/51243175/mod_plua_vs2010.7z
Self-answer:
The primary reason for the failure to compile was the Lua .lib file. The Microsoft compiler does strange things when dealing with C code, so I got an appropriately compiled version of the .lib from the LuaBinaries SourceForge repository (http://sourceforge.net/projects/luabinaries/) - specifically, 5.2.3/Windows Libraries/Dynamic/lua-5.2.3_Win32_dll10_lib.zip (which is compiled for VS2010).
This didn't enable mod_dbd support, which requires headers and sources from the Apache APR project, but it did allow successful compilation.
You should not be using mod_pLua really, I haven't worked on that for nearly 3 years ;) You should use mod_lua instead, which comes bundled with httpd and works pretty much the same way (although it does not support the php-like scripting that mod_pLua does)
For DBD specific setups (especially how to use it on Windows), see http://modlua.org/api/database

ARM Linking Error "Uses VFP register arguments, main.elf does not" on windows 8 only?

I'm trying to get started on using an ARM STM32F4 Discovery Board and I'm getting some weird compiling errors when using the "GNU Tools" on Windows 8
Currently my code is very simple:
#include "stm32f4xx_conf.h"
int main(void)
{}
This compiles using the "make" command perfectly find on Ubuntu 12 and windows 7, however I get the following error in Windows 8. I installed the same toolchain on all machines.
C:/Program Files (x86)/codesourcery/sourcery g++
lite/bin/../lib/gcc/arm-none-eabi/4.5.1/../../../../arm-none-eabi/bin/ld.exe:
error C:\Users\MyName\AppData\Local\Temp\cckUTM2f.o users VFP register
arguments, main.elf does not
I have narrowed down this error down to the flag "-mfloat-abi=hard", which when switched to "-mfloat-abi=soft", lets the code compile, however this conflicts other files that are previously compiled with "-mfloat-abi=hard".
Does anybody know why this would only occur on Windows 8 and how to fix it? If more information is needed, let me know. Sorry in advance if this is a nooby-question as I'm very new to this!
This answer may appear at the surface to be unrelated, but there is an indirect cause of this error message.
First, the "Uses VFP register..." error message is directly caused from mixing mfloat-abi=soft and mfloat-abi=hard options within your build. This setting must be consistent for all objects that are to be linked.
The indirect cause of this error may be due to the Eclipse editor getting confused by an error in the project's ".cproject" file. The Eclipse editor frequently reswizzles file links and sometimes it breaks itself when you make changes to your directory structures or file locations. This can also affect the path settings to your gcc compiler - for a subset of your project's files. While I'm not yet sure of exactly what causes this failure, replacing the .cproject file with a backup copy corrected this problem for me. In my case I noticed .java.null.pointer errors after adding an include directory path. I also found that a different path to the gcc compiler was being used for some of my sources that were local to the workspace, but not all of them. The two gcc compilers were using different float settings for unknown reasons - hence the VFP register error.
I compared the .cproject settings with a older copy and observed differences in entries for the sources causing the trouble - even though the overriding of project settings was disabled. By replacing the .cproject file with the old version the problem went away, and I'm leaving this as a reminder of what happened.
The solution was actually very simple, it was related to the PATH variable not being set correctly by the toolchain's installer. To solve it in windows 8, go to Environment Variables => System Variables and I added "C:\Program Files (x86)\GNU Tools ARM Embedded\4.8 2014q1\bin" to the path variable. The installer had put it under "User Variables for Name" and that, forever reason, didn't work.

Eclipse + CDT + Cygwin: How do you fix the "Multiple targets" bug?

UPDATE 1:
My original post was too long and obscured the real problem. I have discovered exactly what is causing the "Multiple targets" bug when Make is called.
UPDATE 2:
I found out that this 'Multiple Targets' bug is caused by GNU Make version 3.8.1 (see here1 and here2). GNU Make 3.8.1 is the current GNU Make released with Cygwin. To summarize the link: The old v3.8.0 handled windows paths fine and the newer v3.8.1 reports errors for windows paths (maybe it's a passive aggressive jab from the FSF?).
When you start a new project in Eclipse+CDT+Cygwin w/o external includes/libraries, everything works fine for me.
As soon as I try to use an external include/library I get the "Multiple targets" bug.
Here is exactly the steps needed to reproduce the bug on Windows+Eclipse+CDT+Cygwin:
Project project properties --> C/C++ Build --> Settings --> Tool Settings --> Cygwin C Compiler --> Includes --> Include Paths (-I) -- > Add Button --> Pick directory --> "C:\dir1\dir2"
I hit build.
It builds with no errors the first time.
I hit build again... I get build errors "Multiple targets. Stop.".
I click on the error.
Eclipse pulls up a makefile. The error happens when make sees the windows path for the new include file from the external library:
# NOTE: Error happens when the first "C:/" occurs
src/main.d src/main.o: ../src/main.c C:/dir1/dir2/ExternalLibrary.h
The reason for Make getting an error "Multiple targets" is because it sees the ":" which is part of the Make syntax for declaring a target. When there are two ":", Make errors out because it doesn't know what to do with "Multiple targets."
I can not edit the makefiles manually because they are immediately regenerated and overwritten [UPDATE: by Eclipse-CDT]. Given that I can't manually edit the makefile.
Is there any way for Eclipse to NOT use the "C:\" path? or tell make to ignore the "C:\" path?
Is this an Eclipse+CDT+Cygwin bug?
If you use Eclipse+CDT+Cygwin... please lend a hand (I don't want to use Visual Studios...)! Maybe I am using Eclipse+CDT+cygwin wrong? How do YOU get External Library includes to work?
*Very very frustrated*
Trying to stay Open-Source and cross-platform user,

Turns out the "multiple targets" issue is caused by the current version of GNU Make installed from Cygwin. GNU Make 3.8.1 is the current GNU Make released with Cygwin.
The GNU Make 3.8.1 does not handle windows paths that contain "C:\". So every time your make file has a windows path with "C:\" you get a build error "multiple targets".
The solution I ended up doing is to download a fixed GNU Make v3.8.1. See Here1 or Here2. Then Eclipse+CDT+Cygwin worked fine again.
Update (05-feb-2015):
With an updated cygwin and a new Make (4.0.x) then the problem goes away.
https://superuser.com/questions/154418/where-do-i-get-make-for-cygwin
Had a such a problem, too. Problem was that I included paths on the project settings. Then I had absolute paths. When including the paths in the folder settings with relative paths it worked fine.
I still Got the same problem with eclipse/CDT Juno after update cygwin
to fix it:
you need make 3.80-1 or older and this needs cygintl-2.dll.
download make3.80-1 from
http://www.filewatcher.com/m/make-3.80-1.tar.bz2.286814-0.html
and the needed Dll from
http://www.dllguru.com/cygintl-2.dll.html
extract it somewhere
rename your make in cygwin/bin to makeVersion e.g. make3.82.90
copy cygintl-2.dll and make into cygwin/bin
try build your project in eclipse twice, the problem should be disappeared

MSVCR90.DLL was not found

I know a question like this was already asked, but the situation is a little different, and all the answers on that problem didn't work for me.
I'm trying to compile some C code in VS2008 and it doesn't create an exe. Also, when I try to run it with f5, I get:
This application has failed to start
because MSVCR90.DLL was not found.
I did some googling and it said that this was because my c++ redistributable package wasnt installed. So I installed that, restarted everything and tried again. But alas, I still get the same error. Does anyone have any clue how to fix this?
It sounds like either a problem with your VS2008 installation, or something wrong with your DLL search path. MSVCR90.DLL is installed when you install VS2008, you shouldn't have to install any additional redistributable packages.
First I would check your PATH environment variable and make sure there is no gobbledydook in it that will break some of the entries, and if you don't find a problem there, then I would uninstall and reinstall Visual Studio.
You could also try searching for MSVCR90.DLL (and other DLLs like it), and move them to your Windows/System32 folder.
If you just want to get going now, another thing you could do is change your project to statically link to the runtime libraries, and then it wont even try to load that DLL. Go to your Project settings, Configuration Properties->C/C++->Code Generation and change Runtime Library from Multi-Threaded DLL to just Multi-Threaded (or any of the options that doesn't end with DLL).
Here are some things to check for your configuration of the project- under the general tab:
.1 Configuration type - exe in your case.
.2 Use of MFC: if this is an MFC application it might be more portable if you do: Use MFC in a static library.
.3 Use of ATL - if not using atl (or not sure) say Not using ATL.
.4 Under C/C++ -> Runtime Library: Say Multi-threaded Debug (for debug version) or Multi-Threaded (for release version).
If you are getting specific linker errors that say something is already defined:
This means that you have some parts of your app (separate libs being linked to your exe) that are built with different runtime linking:
You can:
Make sure that these libraries were compiled with the same version of visual studio as your application.
Change those projects to use static runtime: C/C++ -> Code Generation -> Runtime LIbrary: /MT or MTd (same as #4 above)
If you still have some specific errors try telling the linker to ignore certain libraries: Go to Linker->Ignore Specific Library and put in the library that you want to ignore. This is most common for 'libcmt.lib' or 'libcmtd.lib'. It is important also to know that lib ending with 'd' is usually the debug version. If you are creating a release build and you are getting 'already defined in libcmtd.lib' that means that somewhere you are linking a release lib to a debug lib.
if you delete the manifest file associated with you .exe, you will get the same error.
MSVCR90.dll is not installed in system32, but in the side-by-side folder, hence the manifest is required.
I have just been bitten by this and this page got me working again.
The key is to ignore MSVCRT and MSVCR90 libraries for the debug configuration. Set your linker -> Input -> Ignore Specific Library setting to include the following:
MSVCRT
MSVCR90
it is supposedly in the http://www.microsoft.com/downloads/en/details.aspx?FamilyID=a5c84275-3b97-4ab7-a40d-3802b2af5fc2&displaylang=en visual studio 2008 runtime library. Yes! After installing that, openoffice update works.
If you give the finished exe to someone else they will need to install the latest visual c runtime to run it. This will only work for release build AFAIK. Visual studio should install the required runtime both release and debug into your path. The project probably has an additional dependency accidently set for an incorrect version of the runtime.
See if this page helps.
Go to your Project settings, Configuration Properties->C/C++->Code Generation and change Runtime Library from Multi-Threaded DLL to Multi-Threaded and then try to compile but it won't. Then change it to Multi-Threaded Debug and try to compile ,but it won't again and then you change it back to Multi-Threaded DLL and then it should compile and run.

Why Isn't My C Code Being Compiled To An EXE

I'm just starting out writing trying to write a simple program in C and I am using Visual Studios to do so. I heard that it does compile C as well as C++. And I know that it does because it says it compiles. The only problem is that when I go to the output directory, there isn't a .exe file in the directory! It has the following:
BuildLog.html
mt.dep
test1.obj
vc90.idb
vc90.pdb
But that is all! No EXE. I've looked through all the options and made sure that it is set to compile to an exe and i checked the output file. That is $(OutDir)\$(ProjectName).exe. But alas, no exe appears. Any ideas?
Also when i try to hit f5 and run with debut i get an error that says
This application has failed to start
because MSVCR90.DLL was not found.
Re-installing the application may fix
this problem
By default when you're creating a new C++ project within a new solution, you're getting folder structure like this:
C:\Projects\YourSolution
C:\Projects\YourSolution\YourCppProject
YourSolution contains YourSolution.sln and YourCppProject contains YourCppProject.vcproj.
When you build the solution, all intermediate files from YourCppProject are getting stored under YourCppProject\Debug or YourCppProject\Release, but resulting YourCppProject.exe goes under YourSolution\Debug or YourSolution\Release.
Your $(OutDir) is configured by General -> Output Directory. Check project configuration for YourCppProject and see that it uses $(SolutionDir) for the output.
is it a C/C++ console application?
did you use the project wizard to create it?
do you have a function like
#include "stdafx.h"
int _tmain(int argc, _TCHAR* argv[])
{
printf("Hello, world!\n");
return 0;
}
in a .c module, typically main.c?
what happens when you hit F5 to run-with-debug?
what does your build log look like?
The simplest thing to do is just start over, making sure you choose the right kind of project.
To compile plain old C code with Visual Studio, choose Visual C++ > General > Empty Project from the New Project menu. This creates 3 empty folders: Header Files, Resource Files, and Source Files. Right click on Source Files, choose Add > New Item. Then add a main.cpp, rename it to main.c, and start coding.

Sounds like you only hit compile, that will give you you're .obj file, but you still need to click build.
