例えば、
Fedora Core 1 で NetBSD-powerpc 用を作って見る
735 tar zxf ../binutils-2.14.tar.gz 736 cd binutils-2.14/ 739 ./configure --target=powerpc--netbsd 740 makeこれで、NetBSD/macppc の /bin/ls を objdump して見る 767 binutils/objdump -d /tmp/ls |less ＠ 何故か逆は問題があって作れない:
./configure --target=i386-redhat-linux
make binutils-2.14/opcodes/./disassemble.c:286: undefined reference to `print_insn_little_powerpc' 118 16:36 make clean 119 16:36 ./configure --target=i386--freebsd 120 16:36 makeこれは出来た。 ＠ make clean していなかったせい ?:128 16:43 make clean && ./configure --target=i386--linux 129 16:43 make 130 16:48 binutils/objdump -d /tmp/ls | less出来た。 ( つっこみ )
