edwin 2008-07-03 22:37:51 UTC FreeBSD src repository Modified files: usr.bin/ldd ldd.1 ldd.c Log: SVN rev 180236 on 2008-07-03 22:37:51Z by edwin On 64 bit architectures, you can run 32 bit executables and the rtld can trace them, but ldd(1) doesn't know yet how to detect them: [/] root@ed-exigent>ldd `which httpd` ldd: /usr/local/sbin/httpd: can't read program header ldd: /usr/local/sbin/httpd: not a dynamic executable But... [/] root@ed-exigent>LD_32_TRACE_LOADED_OBJECTS==1 `which httpd` libm.so.4 => /lib32//libm.so.4 (0x280c8000) libaprutil-1.so.2 => /usr/local/lib/libaprutil-1.so.2 (0x280de000) libexpat.so.6 => /usr/local/lib/libexpat.so.6 (0x280f2000) libiconv.so.3 => /usr/local/lib/libiconv.so.3 (0x28110000) libapr-1.so.2 => /usr/local/lib/libapr-1.so.2 (0x281fd000) libcrypt.so.3 => /lib32//libcrypt.so.3 (0x2821d000) libpthread.so.2 => not found (0x0) libc.so.6 => /lib32//libc.so.6 (0x28235000) libpthread.so.2 => /usr/lib32/libpthread.so.2 (0x2830d000) Added support in ldd(1) for the LD_32_xxx environment variables if the architecture of the machine is >32 bits. If we ever go to 128 bit architectures this excercise will have to be repeated but thanks to earlier commits today it will be relative simple.
