Faye Chun 9bb9d548ad stepmania: fix aarch64-linux build by using libpng from nixpkgs ... Currently, the aarch64-linux build of Stepmania fails with libpng linkage errors: > ld: ../extern/libpng.a(pngrtran.c.o): in function `png_do_read_transformations': > pngrtran.c:(.text+0x4118): undefined reference to `png_riffle_palette_neon' > ld: pngrtran.c:(.text+0x5188): undefined reference to `png_do_expand_palette_rgba8_neon' > ld: pngrtran.c:(.text+0x6268): undefined reference to `png_do_expand_palette_rgb8_neon' > ld: ../extern/libpng.a(pngrutil.c.o): in function `png_read_filter_row': > pngrutil.c:(.text+0x6734): undefined reference to `png_init_filter_functions_neon' > collect2: error: ld returned 1 exit status Stepmania vendors many dependencies in source form in their code repository; it appears that the libpng build configured there seems to be either misconfigured or isn't building correctly under NixOS. I played around with a couple of NEON-related compile flags but couldn't get anything to stick. A workaround that works seems to be building against the Nixpkgs libpng instead. It builds, launch, and (so far) plays correctly on my NixOS-based M1 Air and my PC.		2024-02-02 23:26:29 -05:00
