Hello, I'm trying to compile bash-4.0 with gcc-4.4.0. Bash was configured with the following options: --prefix=/tools --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu Please notice I have set CFLAGS environment variable to: -O2 -march=core2 -Wl,--dynamic-linker=/tools/lib/ld-linux-x86-64.so.2 Of course I have glibc installed in /tools. Well, bash get configured and compiled fine, but then if I issue ldd bash I get the following: linux-vdso.so.1 => (0x00007fffcb3ff000) libncurses.so.5 => not found libdl.so.2 => /tools/lib/libdl.so.2 (0x00007f14c2e65000) libc.so.6 => /tools/lib/libc.so.6 (0x00007f14c2b0d000) /tools/lib/ld-linux-x86-64.so.2 (0x00007f14c3069000) I have not installed ncurses in /tools. If I install it before attempting to compile bash, the problem is fixed. But I wonder why gcc does not complain at build-time... I can't check every compiled executable/library with ldd before installing it. Thanks.
