# It's possible (for near-UNIX clones) that sys_errlist doesn't exist if test $ol_cv_dcl_sys_errlist = no ; then

above lines are from configure script , i don't want my binaries and libraries do be dependent on the symbols of errlist and nerr .

As per mail trace "Re: How to get rid of sys_errlist and sys_nerr? - OpenLDAP" , this issue seems to existing from long back. The solution given is still not working.

I am trying to compile my binaries in a machine with has glibc 2.5 . Then i take these ldap libraries to link with the other process which is getting compiled in glibc 2.3.4.

I am compiling with option of ol_cv_dcl_sys_errlist=no , so that i can disable offending symbols (sys_nerr and sys_errlist). configure go smooth but compilation fails.

Below is the compilation failure trace.

What makes you think this is an OpenLDAP issue? The error message clearly says sys_errlist.h was included from stdio.h - we have no control over that.
