I am programming C on VSCODE but I have this annoying problem. When vscode automatically saves my work, it deletes the line that has the library inclusion that I need. So when I compile it gives me an error that I did not specify the function. Someone can help me?
I don't know how to resolve.
You might have installed a corrupted version of vs code or the library files of the vs code and then location where you are saving your programs might be in different location. For example
The libary files of vs code might be in c drive and the program files might be in onedrive folder.
Try reinstalling it from an authentic source if the second stated problem is not the case. If the problem still continues then please comment down on my reply.
Reinstall either from microsoft store or from

I got a makefile project for Linux and I want to compile it on Win10 with Visual Studio 2019.
There are some paths to files defined in the makefile as preprocessor defines.
I have to replace the paths by own created files because they are a kind of PLATFORM_HEADER and I have to adapt a new one to Windows. In the code it looks like:
#include PLATFORM_HEADER
The onliest I tried is to add a property sheet to my project and add a macro:
macro page of property sheet But this macro is not found in the project.
Changing the code is not possible because it is third party code and it must be able to become updated at later times without doing changes again.
In other instructions there is noted that a line called 'inherited property sheet' has to be modified in the project. But in VS2019 this line does not exist.
Thank you for your help!
This sort of problem will be handled by your compiler suite. Probably you'll deal this with your build process manager (make, bitbake, cmake...). You can ask it to pass these #defines as argument for the compilation (-D name=definition).
Now you've unlocked the "very most of fun" if you compile something meant for linux on windows since there are many way that can go wrong. You might want to do a full check of your environment variable when compiling and make sure they point to the right system librairies.
Probably it's worth giving a try to the windows subsystem for linux and other bindings / emulator. If you want to preview a week of work's outcome, maybe you can do it in a linux VM? or just get rid of windows one good time for all :)
I just finished coding my c program in visual studio (VS) and what I had done is just drag the compiled .exe file out of the folder to run it on other computers, except on other computers for that to work I guess I need VS since it says the MSVCR110D.dll is missing which is from VS. So how can I run my program on other computers that don't have VS?
You can use IExpress which is used for distributing self-contained installation packages. It is there in every windows machine preinstalled. Using this utility you can make the executable .exe which will be incorporated with dependent dlls. You can see Step by step guide, to see how to use it.
Follow these steps
https://msdn.microsoft.com/en-us/library/3w7axy17.aspx
In your output window it will show you where you can find the exe file, usually something like "ProjectName/Debug/Release/"
If you have added any external libraries you will have to copy any DLL files in that folder with the exe (You can combine them with some applications if needed)
You will also have to make sure that you have the correct version of the .NET Framework on the PC that you are trying to run your program on
For some reason, our dev deployment is done by copying an updated .dll file to the GAC (Global Assembly Cache) by dragging and dropping it to the C:\Windows\Assembly folder.
I tried to create a batch script that contains the following code:
XCOPY d:\source\sample.dll c:\Windows\Assembly
but this seems to not work.
I was told it is because dragging the .dll into the Assembly folder does not copy it, but installs it somehow.
Is there a way to do this using a batch?
We do this 20 times per day, so its really time consuming to do this manually every time.
Try gacutil. Take a look here it seems like a duplicate.
BTW: Assembly tag is for low-level assembler.
I'm doing some Linux kernel development, and I'm trying to use Netbeans. Despite declared support for Make-based C projects, I cannot create a fully functional Netbeans project. This is despite compiling having Netbeans analyze a kernel binary that was compiled with full debugging information. Problems include:
files are wrongly excluded: Some files are incorrectly greyed out in the project, which means Netbeans does not believe they should be included in the project, when in fact they are compiled into the kernel. The main problem is that Netbeans will miss any definitions that exist in these files, such as data structures and functions, but also miss macro definitions.
cannot find definitions: Pretty self-explanatory - often times, Netbeans cannot find the definition of something. This is partly a result of the above problem.
can't find header files: self-explanatory
I'm wondering if anyone has had success with setting up Netbeans for Linux kernel development, and if so, what settings they used. Ultimately, I'm looking for Netbeans to be able to either parse the Makefile (preferred) or extract the debug information from the binary (less desirable, since this can significantly slow down compilation), and automatically determine which files are actually compiled and which macros are actually defined. Then, based on this, I would like to be able to find the definitions of any data structure, variable, function, etc. and have complete auto-completion.
Let me preface this question with some points:
I'm not interested in solutions involving Vim/Emacs. I know some people like them, but I'm not one of them.
As the title suggest, I would be also happy to know how to set-up Eclipse to do what I need
While I would prefer perfect coverage, something that only misses one in a million definitions is obviously fine
SO's useful "Related Questions" feature has informed me that the following question is related: https://stackoverflow.com/questions/149321/what-ide-would-be-good-for-linux-kernel-driver-development. Upon reading it, the question is more of a comparison between IDE's, whereas I'm looking for how to set-up a particular IDE. Even so, the user Wade Mealing seems to have some expertise in working with Eclipse on this kind of development, so I would certainly appreciate his (and of course all of your) answers.
Cheers
Eclipse seems to be pretty popular for Linux kernel development:

I previously wrote up an answer. Now I come up with all the details of the solution and would like to share it. Unfortunately stackoverflow does not allow me to edit the previous answer. So I write it up in this new answer.
It involves a few steps.
[1] The first step is to modify linux scripts to leave dep files in. By default after using them in the build, those dep files are removed. Those dep files contains exact dependency information about which other files a C file depends. We need them to create a list of all the files involved in a build. Thus, modify files under linux-x.y.z/scripts to make them not to remove the dep files like this:
linux-3.1.2/scripts
Kbuild.include: echo do_not_rm1 rm -f $(depfile);
Makefile.build: echo do_not_rm2 rm -f $(depfile);
The other steps are detailed in my github code project file https://github.com/minghuascode/Nbk/blob/master/note-nbkparse. Roughly you do:
[2] Configure with your method of configuration, but be sure use "O=" option to build the obj files into a separate directory.
[3] Then use the same "O=" option and "V=1" option to build linux, and save make output into a file.
[4] Run my nbkparse script from the above github project. It does:
[4.1] Read in the make log file, and the dep files. Generate a mirroring command.
[4.2] Run the mirroring command to hard-link the relevant source files into a separate tree, and generate a make-log file for NetBeans to use.
Now create a NetBeans C project using the mirrored source tree and the generated log file. NetBeans should be able to resolve all the kernel symbols. And you will only see the files involved in the build.
The Eclipse wiki has a page about this: HowTo use the CDT to navigate Linux kernel source
I have been doing some embedded linux development. Including kernel module development and have imported the entire linux kernel source code into Eclipse, as a separate project. I have been building the kernel itself outside of Eclipse(so far), but I don't any reason why I shouldn't be able to set up the build environment within Eclipse to build the kernel. For my projects, as long as I setup the PATH properties to point to the appropriate linux source include directories, it seems to be pretty good about name completion for struct fields, etc.
I can't really comment, on if it is picking up the correct defines and not greying out the correspond sections, as I haven't really paid to much attention to the files within the kernel itself.(so far)
I was also wondering about using Netbeans as a linux 'C' IDE, as I do prefer Netbean's for Java GUI development.
I think this would work (done each step for various projects):
[1] Modify kernel build scripts to leave .d files. By default they are removed.
[2] Log the build process to a file.
[3] Write a script to parse the build log.
[3.1] From the build log, you know every .c files.
[3.2] From the .c file, you know which is the corresponding .d file.
[3.3] Look into .d files to find out all the included .h files.
[3.4] Form a complete .c and .h file list.
[4] Now create a new dir, and use "ln -s" or "ln" to pick files of interest.
Now, create a Netbeans project for existing source code in the [4].
Configure code assistance to use make-log file. You should see
exactly the effective source code as when you build it at [2].
Some explanations to the above steps:
At [2], do a real build so the log file contains the exact files and flags of interest.
Later netbeans will be able to use the exact flags to parse.
At [4], pick only the files you want to see. Incorporating the whole kernel tree into netbeans will be unpractical.
There is a trick to parsing .d files: Many of the depended items are not real paths to a .h file, they are a modified entry for part of the linux config sections in the auto config file. You may need to reverse the modification to figure out which is the real header file.
Actually there is a topic on netbeans site. This is the discussion url: http://forums.netbeans.org/ntopic3075.html . And there is a wiki page linked from the discussion: wiki.netbeans.org/CNDLinuxKernel . Basically it asks you to prefix make with CFLAGS="-g3 -gdwarf-2" .
I found this link very helpful in setting up proper indexing in Eclipse. It requires running a script to alter Eclipse environment to match your kernel options, in my case
$ autoconf-to-eclipse.py ./include/generated/autoconf.h .
