Cannot build for psp1 platform : "Assembler messages" errors

[pleft]

On an x86 ubuntu machine, I have installed pspdev environment and cannot build libretro core with:
make -f Makefile.libretro platform=psp1

I get error when compiling core/system.c:

any help is appreciated.

Sorry but you will have to report this to the libretro team (https://github.com/libretro/Genesis-Plus-GX/issues) as I don't maintain their Makefile and cannot help you with libretro core compilation.
