## #9827 — Olivier Hill — 2004-05-13T02:33:49+00:00

URL: https://externals.io/message/9827#9827

Good evening,

Over a year ago, Rasmus and Ilia had a discussion on the list about 
building the Apache DSO with non-PIC code.

My question is, what is the easiest way to build with --prefer-non-pic 
using a release tarball? Would it be possible to add a ./configure 
option, because right now I'm editing files manually.

Sincerely,
Olivier

Well, the following is what needs to be changed.  I have not had the
mental energy to figure out the magic incantation to get a configure flag
to do this:
