Summary 06801: Can't link SDL builds on Windows with GCC 7
Description

SDL builds for Windows fail to link with GCC 7 (it works with GCC 5 or GCC 6).


32-bit link error:


Linking sdlmame.exe...
C:/Users/_merlin/msys64/mingw32/lib\libqtmain.a(qtmain_win.o):qtmain_win.cpp:(.text+0x12e): undefined reference to `qMain(int, char**)'
collect2.exe: error: ld returned 1 exit status
mame.make:252: recipe for target '../../../../../sdlmame.exe' failed

64-bit link error:


Linking sdlmame64.exe...                                                                                                        
../../../../mingw-gcc/bin/x64/Release/liblualibs.a: error adding symbols: Malformed archive
collect2.exe: error: ld returned 1 exit status
mame.make:252: recipe for target '../../../../../sdlmame64.exe' failed
make[2]: *** [../../../../../sdlmame64.exe] Error 1

In the 64-bit case, liblualibs.a is not malformed - the same static archive library can be successfully linked into the Win32 OSD version of MAME. Changing the order of the objects in liblualibs.a changes the error message, but it fails to link in any case. The tools link successfully, only the emulator fails.

Steps To Reproduce Build with OSD=sdl in your make arguments.

GCC 7 is no longer supported, so is this still an issue?

GCC 7 is still the minimum supported compiler version for building MAME. I don’t have an MSYS64 setup with such an old GCC version though. It seem odd that this only happens in such specific circumstances – it really looks like a bug in the linker.

You're right, 7.2 is the minimum according to the compiling page, so it must apply to 7.x (I assumed 7.0 only).
