To elaborate, here's my current plan: * Have some drtstuff.c like this #ifdef DRT_BEGIN void *__start_minfo[] __attribute__((used, section("minfo"), aligned(sizeof(void *)))) = { }; #endif #ifdef DRT_END void *__stop_minfo[] __attribute__((used, section("minfo"), aligned(sizeof(void *)))) = { }; #endif and compile it into separate drtbegin.o/drtend.o. * Based on the outcome of DCFG_MINFO_BRACKETING, add them to libgphobos.spec like this: %rename startfile startfile_orig *startfile: %(startfile_orig) drtbegin.o%s %rename endfile endfile_orig *endfile: %(endfile_orig) drtend.o%s * This will have to be done explicitly for libgdruntime.la and libgphobos.la since both are linked with -nophoboslib. Doing the equivalent of this manually allowed the libs to be linked on Solaris 10. However, this was before the section_elf_shared.d work, so the resulting libs had unresolved references.
