I have an application that depends on some .dll files.
I know if I just make them in the same folder as the .exe file, it would work, but I don't want to leave 30 .dll files with my .exe file. Is there a way I can put them in a folder with my .exe file ?
Or even better, is it possible to compile them and link them with the .exe file to have a standalone file? And no I don't have the static version of these dynamic libraries.
(p.s. the application is written with c, compiled with gcc, mingw win64, and the .dll are from gtk3 libs)
Thank you for reading my question
You have a number of options.
A) get hold of the library files, .lib on windows and statically link with these libraries.
B) It is a bit of a hack but you can attach resources into a Windows executable. This is usually used for strings, icons, that sort of thing, but you could even attach in a binary file. But if you do this you would probably need to generate the dll binaries at program startup and save to eg same folder as your executable. So no point in doing this really, simply distribute in the same folder as your exe. What is the problem doing that? (lookup LoadResource, FindResource, MAKEINTRESOURCE, etc)
C) If you don't want to put the dlls is the same path as your exe you will need to store them in a folder in your system's path env variable. Eg you could copy them to C:\Windows - but due to security that will be harder. You could create your own dll_path and add this path to the env variable as part of the installation of your program.
D) One other variation on C) is that you copy to for example a subdirectory of you exe location, called eg dll_files. Then you use a startup script to launch your program like this:
#echo off
set PATH=%PATH%;<path to dll files>
myprogram.exe
Let's make is simple
download winrar from www.rarlab.com/download.htm A) create standalone winrar executable pack your file in archive and execute your main program.
no idea how to create standalone installer guide for you

I was looking for a quick and easy way to automatically send a file to my gmail for debugging purposes on multiple remote machines. However I am apparently having linking issues which I can't seem to solve.
I downloaded the win64 zip file of libquick, IDE is CodeBlocks, compile target is x64 and running on 64-bit Windows 10.
There were 10 files that came in the zip folder, in lib/include/bin. They were
bin > libquickmail-0.dll, libquickmaillight-0.dll, quickmaillight.exe.
include > quickmail.h.
lib > libquickmail.a, libquickmail.dll.a, libquickmail.la, libquickmaillight.a, libquickmaillight.dll.a, libquickmaillight.la.
I linked to all of the .a/.dll.a/.la and .dll files and it still gives me this error: Code execution cannot proceed because libquickmail-0.dll was not found
I have no idea what the problem is and am very open to ideas. Thank you for your time.
Either copy the libquickmail-0.dll to the same directory as your linked executable or add the libquickmail bin directory to your path. This will allow Windows to find the DLL to run the executable.
I recently built a project on VisualStudio. I got an executable in the bin folder and I put all the dependencies x64 DLL in C:\Windows\System32 and all the x32 DLL in C:\Windows\SysWOW64
When I execute my executable, I get an error message This program can't start because foo.dll is missing from your computer.
I tried to get the dependencies with ldd.exe on Cygwin, but I don't see any references to foo.dll. I also tried to execute from PowerShell Start-Process -PassThru sample.exe, but I still get the same error message.
Where does Windows executables look for DLLs?
I've read that a Windows executable will look for its dependencies in a certain order:
In the local folder
In System32
In the %PATH%
I also read that I may need to use regsvr32.exe to register my DLL if it is located into System32.
What is the actual reality of this story?
Alternatively, you can simply add the DLL files to the bin folder as well.
I am able to successfully cross-compile a binary file that can run on an ARM system such as Rasberry Pi. Without linking to a third-party library, normal C++ code runs on the device successfully (I.E. cout << "Hello World!" << endl;).
The issue I'm running into is that when I run the executable after it's been linked against a third-party library, I get the standard UNIX error "No such file or directory." when the binary tries to access the shared object file. I have the file it's looking for copied into the usr/lib folder, the usr/local/lib folder, and the folder where the executable is sitting itself.
Also, I went and added a good value to LD_LIBRARY_PATH so the runtime linker can search at these locations. My guess is that the "system" maybe hiding these files from the executable?
And to add more information, I ran the readelf command on the binary and the shared object file and it gives me the proper descriptions of the file. It tells me that the binary file is a 32-bit file and requires this shared object library file that I mentioned it cannot find. Even during link time in the build phase, I add the following linker command -Wl,-rpath, to set the location of where to look for the shared object file. Please note I'm compiling on a Macintosh Machine, and not on the Rasberry Pi itself. Hence cross-compiling.
I have a feeling it's a setting, because the object file is visible/valid in multiple locations. If anyone has experienced this before, please any advice is appreciated. Thanks in advance.
I actually figured out the problem recently.
The problem was that I was using Eclipse. The third party library files I was using were named in the format "libSHAREDFILENAME.so". Eclipse doesn't like that very much when setting up which libraries to use in the IDE. It expects you to strip off the "lib" and the ".so" portion from the file name. So a file named "libSHAREDOBJECT.so" should be referenced as "SHAREDOBJECT" in Eclipse. It doesn't like the "lib" prefix or the ".so" suffix.
I have an executable that is generated using VC++. The VC++ project includes some of the dlls and when I tried double clicking the exe, it is asking for the path of the dll's.
Is it possible to place the generic dll's into a common folder, open the exe file using the batch file and provide the reference path of the dll's??
See this link for information on DLL search order on Windows.
Quick and incomplete summary:
The directory where the executable module for the current process is located.
The current directory.
The Windows system directory.
The Windows directory.
The directories listed in the PATH environment variable.
Note: The LIBPATH environment variable is not used.
EDIT
To address the comment about having the external DLLs copied locally:
After adding the files to your project, right-click one, select Properties. In the General section, change Item Type to Custom Build Tool. Now in the new section Custom Build Tool, change the Command Line to copy that particular file to the output directory.
You can also do all the necessary file copying in the Pre/Post-build steps of the project.
I need to use the library libMPSSE.dll in my win32 console application project in MSVC 2010. After writing the code I just copied the dll in the folder where my .cpp file is present. I am able to compile successfully but the issue is I am having linking error:
libMPSSE.dll : fatal error LNK1107: invalid or corrupt file: cannot
read at 0x308
Is it really a problem with the dll itself or is there any problem with the dll path. How do we add dll to projects?
They have not provided any .lib file. The complete code is here
These are the usual steps to link to a DLL:
Include the DLL's header file in any of your source files that need to use functions from the DLL. You'll typically need to make sure that your build environment's include path contains the location of the header file. In the IDE you can do this using the Additional Include Directories configuration setting.
Pass the DLL's .lib file to the linker. In the IDE you do this by adding the .lib file to the Additional Dependencies setting. And you'll typically need to add the path to the .lib file to the Additional Library Directories setting.
Having done that, your program should compile and link. To make it run, you'll need to ensure that the DLL itself can be found at runtime. The simplest way to make that happen is to put it in the same directory as the executable file.
My guess, looking at your error message, is that in step 2 you passed the .dll to the linker rather than passing the .lib file.
As said here earlier you can't link to .dll files with C linker directly.
There're win32 APIs that can load the .dll file and return to you pointers to function.
Usually, .dll file is accompanied with .lib file contains code that does this burden for you and provides the API .dll file exposes. All you need is to link to this .lib file and put .dll file near the .exe file created.
Specifically regarding libMPSSE, it's said in its release notes that you can rename the provided .a file to .lib file to link to it in Visual Studio (Project properties->configuration properties->Linker->Input). I tried it and it works as supposed.
