Re: Using non-system glibc

[Mahmood Naderan <nt_mahmood@yahoo.com>]

On the way to use a custom glibc build, I tried to modify the Makefile of the program (nginx) with 


-Wl,--rpath=/opt/glibc-2.23-install -Wl,--dynamic-linker=/opt/glibc-2.23-install/lib/ld-2.23.so

After build and install, I see the following ldd output

$ ldd install/sbin/nginx
        linux-vdso.so.1 =>  (0x00007ffd6c335000)
        libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007fad02350000)
        libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fad02133000)
        libcrypt.so.1 => /lib/x86_64-linux-gnu/libcrypt.so.1 (0x00007fad01efb000)
        libpcre.so.3 => /lib/x86_64-linux-gnu/libpcre.so.3 (0x00007fad01c8b000)
        libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007fad01a71000)
        libc.so.6 => /opt/glibc-2.23-install/libc.so.6 (0x00007fad016d0000)
        /opt/glibc-2.23-install/lib/ld-2.23.so => /lib64/ld-linux-x86-64.so.2 (0x00007fad02554000)



The last line shows that my own glibc build is using system libc. But the lic.so.6 file my program is using, comes from my own glibc build.

So, is that all? Or something is missing? Any advice?
