In short, the best answer is because that's .dll s are Microsoft's answer for shared objects on their 32-bit and 64-bit operating systems. On Windows, MinGW / MinGW-w64's port uses Microsoft C runtime (msvcrt.dll) [1], so it obeys Windows OS linker rules.
Aug 1, 2023 · We employ the conditional statement if(CMAKE_CXX_COMPILER_ID STREQUAL "GNU") to determine whether the compiler in use is MinGW GCC or MSVC. In the case of MinGW GCC, the DLL files in the bin folder are linked. Conversely, for MSVC, we link the LIB files in the lib folder..

If all you care about is the GNU toolchain then DLLs are straightforward,working mostly like shared objects on other platforms. To illustrate,let’s build a “square” library with one “exported” function, square,that returns the square of its input (square.c): The header file (square.h): To build a stripped, size-optimized DLL, square.dll: Now a test...
Mingw-w64-compiled DLLs will work with LoadLibrary out of the box, whichis sufficient in many cases, such as for dynamically-loaded plugins. Forexample (loadlib.c): Compiled with MSVC cl (via vcvars.bat): However, the MSVC toolchain is rather primitive and, unlike the GNUtoolchain, cannot link directly with DLLs. It requires an importlibrary. Conve...
Going the other way, building a DLL with MSVC and linking it withMingw-w64, is nearly as easy as the pure Mingw-w64 case, though itrequires that all exports are tagged with dllexport. The /LD (casesensitive) is just like GCC’s -shared. cl outputs three files: square.dll, square.lib, and square.exp.The last can be discarded, and the second will be n...
If your program is designed to be portable, those __declspecwill get inthe way. That can be tidied up with some macros, but even better, thosemacros can be used to control ELF symbol visibility so that the libraryhas good hygiene on, say, Linux as well. The strategy will be to mark all API functions with SQUARE_API andexpand that to whatever is nec...
While Mingw-w64 hides a lot of the differences between Windows andunix-like systems, when it comes to dynamic libraries it can only do somuch, especially if you care about import libraries. If I were maintaininga dynamic library — unlikely since I strongly prefer embedding or staticlinking — I’d probably just use different Makefiles per toolchainan...
Aug 28, 2018 · MinGW is installed in folder C:\msys64 on my machine. To compile 64-bit executables, you need to start the 64-bit shell first: launch C:\msys64\mingw64.exe. Then you can compile the DLL: gcc -shared -o DemoDll-x64.dll DemoDll.cpp. For 32-bit executables, it’s the 32-bit shell: launch C:\msys64\mingw32.exe. Then you can compile the DLL:
Jun 4, 2010 · Remember to name your static libraries *.a and your shared library *.so so that they will not be confused as Windows specific *.lib and *.dll libraries. In my next article, I will describe generating libraries in Microsoft Visual C++ and using classes.
Sep 7, 2016 · Just make sure the path to your MinGW bin folder is linked to your system path, and you should be able to use ncurses without trouble. By the way, be certain to use the -lncurses option when you compile your code.

Jul 7, 2022 · But if the file that is found is an ordinary object file, it is linked in the usual fashion. The only difference between using an -l option and specifying a file name is that -l surrounds library with lib and .a and searches several directories.
