[Mesa3d-users] Simple compilation question - re Linking against an alternate/parallel set of libraries

[Ashley H. <ash...@ya...>]

OK, I'm managed to install libdrm and am attempting to compile Mesa against it.
 The compile works, but when I run ldd on the compiled files I notice that many
of them are linked against the shared libraries in /usr/lib, which are the
libraries for the version of X11 installed as part of main install.  I am
building the parallel X11 install in my homedir, and have completed it with the
exception of the modules that depend on Mesa.

I would like Mesa to be built against my new, parallel install of X11 and
libdrm, but each time I compile it ends up linking against the libdrm.so.2 in
/usr/lib (see below).

In the shell I'm doing compilation in, I've set both LIBRARY_PATH and
LD_LIBRARY_PATH as follows:

LIBRARY_PATH=/home/hooperas/build/modular/lib:/home/hooperas/build/libdrm/lib
LD_LIBRARY_PATH=/home/hooperas/build/modular/lib:/home/hooperas/build/libdrm/lib

I don't have an /etc/ld.so.conf file but my understanding is that the LD path
above will be used in preference to the LD cache anyway.

After doing a make realclean && make linux-dri-x86, here's what ldd tells me
when I run it on the newly compiled LibGL.so:

~/build/Mesa/lib$ ldd libGL.so
        linux-gate.so.1 =>  (0xffffe000)
        libX11.so.6 => /usr/lib/libX11.so.6 (0xb7db1000)
        libXext.so.6 => /usr/lib/libXext.so.6 (0xb7da4000)
        libXxf86vm.so.1 => /usr/lib/libXxf86vm.so.1 (0xb7d9f000)
        libm.so.6 => /lib/tls/i686/cmov/libm.so.6 (0xb7d7d000)
        libpthread.so.0 => /lib/tls/i686/cmov/libpthread.so.0 (0xb7d6a000)
        libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xb7d67000)
        libdrm.so.2 => /usr/lib/libdrm.so.2 (0xb7d60000)
        libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7c31000)
        libXau.so.6 => /usr/lib/libXau.so.6 (0xb7c2e000)
        /lib/ld-linux.so.2 (0x80000000)
