On Linux/x86-64, when binutils is configured with --libdir=/usr/lib64, genscripts.sh treats /usr/lib64 as the default search directory. It put /usr/lib64 in linker scripts for all emulations, like --- /* Script for -z combreloc: combine and sort reloc sections */ OUTPUT_FORMAT("elf32-i386", "elf32-i386", "elf32-i386") OUTPUT_ARCH(i386) ENTRY(_start) SEARCH_DIR("/usr/x86_64-redhat-linux/lib32"); SEARCH_DIR("/usr/i386-redhat-linux/lib32"); SEARCH_DIR("/usr/lib6432"); SEARCH_DIR("/usr/local/lib32"); SEARCH_DIR("/lib32"); SEARCH_DIR("/usr/lib32"); SEARCH_DIR("/usr/i386-redhat-linux/lib"); SEARCH_DIR("/usr/lib64"); SEARCH_DIR("/usr/local/lib"); SEARCH_DIR("/lib"); SEARCH_DIR("/usr/lib"); --- When I install my own 32bit GCC on Linux/x86-64, I got: [hjl@gnu-atom-1 tmp]$ /export/build/gnu/gcc-32bit-4.7/release.original/usr/gcc-4.7.4/bin/gcc x.o /usr/bin/ld: skipping incompatible /usr/lib64/libc.so when searching for -lc [hjl@gnu-atom-1 tmp]$
