[uClibc]libcrypt and libdl linking

[Cédric Schieli]

Hello

There still seems to be a problem of linking from libdl (and libcrypt).
I build uClibc on a i386 RH6.2 system and that's what ldd report :

[cedric at tron cedric]$ ldd /usr/i386-linux-uclibc/lib/libcrypt.so.0
        /lib/libNoVersion.so.1 => /lib/libNoVersion.so.1 (0x40005000)
        libc.so.0 => /usr/i386-linux-uclibc/lib/libc.so.0 (0x40010000)
        libc.so.6 => /lib/libc.so.6 (0x4003f000)
        ld-linux-uclibc.so.0 =>
/usr/i386-linux-uclibc/lib/ld-linux-uclibc.so.0 (0x40134000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)
[cedric at tron cedric]$ ldd /usr/i386-linux-uclibc/lib/libdl.so.0
        /lib/libNoVersion.so.1 => /lib/libNoVersion.so.1 (0x40004000)
        libc.so.0 => /usr/i386-linux-uclibc/lib/libc.so.0 (0x4000f000)
        libc.so.6 => /lib/libc.so.6 (0x4003e000)
        ld-linux-uclibc.so.0 =>
/usr/i386-linux-uclibc/lib/ld-linux-uclibc.so.0 (0x40133000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

I don't see why those dependencies appear since they are built with
i386-uclibc-gcc...

The final linkage for libdl is done by this gcc invocation :

../../extra/gcc-uClibc/i386-uclibc-gcc --shared -nostartfiles -nostdlib
-v \
-o libdl.so.0 -Wl,-soname -Wl,libdl.so.0 \
*.o ../../uClibc-0.9.5.so

Any idea ?
