So, you > should need use the -nostdlib option. :) Maybe you mean the -nodefaultlibs option :) Now I get: $ gcc dummy.c -nodefaultlibs -L/tools/lib /usr/lib/gcc/x86_64-pc-linux-gnu/4.3.3/../../../../lib64/crt1.o: In function `_start': (.text+0x12): undefined reference to `__libc_csu_fini' /usr/lib/gcc/x86_64-pc-linux-gnu/4.3.3/../../../../lib64/crt1.o: In function `_start': (.text+0x19): undefined reference to `__libc_csu_init' /usr/lib/gcc/x86_64-pc-linux-gnu/4.3.3/../../../../lib64/crt1.o: In function `_start': (.text+0x25): undefined reference to `__libc_start_main' collect2: ld returned 1 exit status Or, if I use the -B switch instead of the -L switch: $ gcc dummy.c -nodefaultlibs -B/tools/lib /tools/lib/crt1.o: In function `_start': (.text+0x12): undefined reference to `__libc_csu_fini' /tools/lib/crt1.o: In function `_start': (.text+0x19): undefined reference to `__libc_csu_init' /tools/lib/crt1.o: In function `_start': (.text+0x25): undefined reference to `__libc_start_main' collect2: ld returned 1 exit status
