static linking

[audetto]

Add ability to link statically as much as possible.

It is particularly important for msys2, where non-Windows DLLs cannot be easily found when exes are executes outside a msys2 environment.

But it will help other cases too.

Hello. Tried to compile the static-working branch on mingw64 and I got the following error message:

C:/apps/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/14.2.0/../../../../x86_64-w64-mingw32/bin/l
d.exe: C:/apps/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/14.2.0/../../../../lib\libminizip.a(
unzip.o):(.text+0x1e60): undefined reference to `BZ2_bzDecompress'

Looks like bzip2 is a dependency of minizip and is not included in the static link. I will try to install the bzip2 package and see how it goes

It is not ready. I am trying (and so far failing) to understand static linking in cmake.

No problem, it was just to give a feedback, no complain here 😉By the way, I did manage to have a successful compilation with this patch:

However, it does not work when I put it in RA, with or without extra dll.

The branch now works in linux and static links as much as I think it is humanly possible.

In msys2 it compiles, looks to be more static, but I was not able to test it for real. Will do it in the next days.

ldd still shows 1 non-windows dll

libwinpthread-1.dll => /mingw64/bin/libwinpthread-1.dll (0x7ffef2450000)

does it matter?

#230

libwinpthread is distributed with retroarch, so I think it's ok 😊

I can confirm that it now works perfectly in retroarh without any added dll. Thanks !
