Unable to build FastDDS 2.9.1 for MSYS2 mingw32 on Windows11

[githubposter12]

Hi all,
I'm trying to evaluate FastDDS, and attempting to build FastDDS for windows with MSYS2 mingw32.
I've either installed msys2 packages for all dependencies or compiled to /usr/local.

I also installed:

$ pacman -S msys2-w32api-headers
$ pacman -S msys2-w32api-runtime

I was able to build FastCDR.
But I get a compile error when building FastDDS itself (see below).

I'm guessing I'm missing the correct thread library, but I don't know which.
I've tried winpthread, mcfgthread.

Thanks for any help.
Regards.

Hi @githubposter12

It seems like some of the OS guard protections in the TimedMutex might not be the correct ones (using WIN32 instead of MSVC and vice-versa probably). Probably, there are other parts of Fast DDS that has this same issue. That is the most probable reason why Fast DDS can be built in Windows using Visual Studio but it fails using MinGW. Currently there is no plan to support MinGW but you may be interested on contacting eProsima commercial support for options.

hi @JLBuenoLopez-eProsima
thank you for replying. would you accept patches for a MinGW build? even if it's not officially supported?
Regards.

[JLBuenoLopez]

Sure, there are other communities that contribute changes to ensure building in non-officially supported platforms (like QNX for instance). However, as Fast DDS CI does not build with MinGW, it cannot be assured that it would not be broken again with some further development. But any contribution is welcomed!
