Maybe do (setenv "CC" #$(cc-for-target)) first? * Likewise, TARGET-pkg-config instead of pkg-config (not 100% sure) * It tries to run binaries during ./configure. When cross-compiling, ./conftest will always fail (unless using emulation) and hence always detect =E2=80=98little endian=E2=80=99 but this is incorrect when cross-compiling for big-endian architectures. (Needs some fixes or work-arounds.) You can test with "guix build azpainter --target=3Daarch64-linux-gnu" or such. Also, some other problems. From mlk_studio.c int mFILEreadBE32(FILE *fp,void *buf) { uint8_t v[4]; if(fread(v, 1, 4, fp) < 4) return 1; else { *((uint32_t *)buf) =3D ((uint32_t)v[0] << 24) | (v[1] << 16) | (v[2] << 8) | v[3]; return 0; } } looks like a potential strict-aliasing violation to me, resulting in undefined behaviour -- what if buf is a pointer to an array of, say, doubles? =C2=A0Also a potential alignment problem, though maybe it's only called for sufficiently aligned 'buf'. The strict-aliasing problem can be worked around with -fno-strict-aliasing or maybe just -fno-ipa- strict-aliasing , though I don't know if that's sufficient.
