If e2fsprogs has been compiled with gcc 4.3 and you try to compile sys-boot/silo you'll get this: ld -m elf32_sparc -N -Ttext 0x280000 -Bstatic -o second crt0.o decomp.o ../common/console.o ../common/printf.o malloc.o ../common/jmp.o ../common/prom.o ../common/tree.o ../common/urem.o ../common/udiv.o ../common/stringops1.o ../common/ffs.o ../common/divdi3.o ../common/udivdi3.o bmark.o main.o cmdline.o disk.o file.o misc.o cfg.o strtol.o ranges.o timer.o memory.o fs/libfs.a mul.o ../common/rem.o ../common/sdiv.o umul.o ../common/stringops2.o ls.o muldi3.o -lext2fs mark.o /usr/lib/libext2fs.a(inline.o): In function `ext2fs_find_next_bit_set': (.text+0xb2c): undefined reference to `__ffssi2' /usr/lib/libext2fs.a(inline.o): In function `ext2fs_find_next_bit_set': (.text+0xb4c): undefined reference to `__ffssi2' /usr/lib/libext2fs.a(inline.o): In function `ext2fs_find_next_bit_set': (.text+0xb7c): undefined reference to `__ffssi2' /usr/lib/libext2fs.a(inline.o): In function `ext2fs_find_first_bit_set': (.text+0xbe0): undefined reference to `__ffssi2' /usr/lib/libext2fs.a(inline.o): In function `ext2fs_find_first_bit_set': (.text+0xc08): undefined reference to `__ffssi2' make[1]: *** [second] Error 1 For now we patched silo(sys-boot/silo/files/gcc-4.3-compile.patch) to include libgcc and it works but other applications that use ext2fs_find_first_bit_set will also experience this error, therefore e2fsprogs should be patched to include libgcc.a when creating libext2fs.a.
umm, no. we're not going to break apart libgcc.a and throw it into random static archives to appease random applications. if you invoke ld directly, you get to pick up the pieces.
