Using non-system glibc

[Mahmood Naderan <nt_mahmood@yahoo.com>]

Hi
How can I use a custom glibc instead of the default system version?
I tried nginx with:


    $ GLIBCDIR=/opt/glibc-2.23-install 
    $ ./configure --with-ld-opt="-Wl,--emit-relocs"
    $ make && make install


But the final binary has no sign of my glibc installation


    $ ldd install/sbin/nginx
            linux-vdso.so.1 =>  (0x00007ffc07d43000)
            libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f0a8d2f3000)
            libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f0a8d0d6000)
            libcrypt.so.1 => /lib/x86_64-linux-gnu/libcrypt.so.1 (0x00007f0a8ce9e000)
            libpcre.so.3 => /lib/x86_64-linux-gnu/libpcre.so.3 (0x00007f0a8cc2e000)
            libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007f0a8ca14000)
            libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f0a8c64a000)
            /lib64/ld-linux-x86-64.so.2 (0x00007f0a8d4f7000)


Any guess?
