RE: unable to compile mod_perl under perl 5.10.1

Hi Fred

Thanks for the answer. getting correct -fPIC is probably the solution, but how?

On perl 5.10.0 it turned up under config flags, but here it does not, but under cccdlflags in dynamic linking?
There is probably some parsing in the Configure script that rearrange it.

platform is CentOS 5.2 (latest patches)

Have you verified perl was actually compiled with fpic?  perl -V
