I’m attempting to debug a problem with a ruby module I wrote in C and am receiving a warning from ld which may be causing the segfault. Does anyone know what can cause this warning? …/bin/ld: warning: creating a DT\_TEXTREL in object. Jeff. ---

The extconf file already contains directive -fPIC $ cat extconf.rb require ‘mkmf’ $CFLAGS=“-O2 -pipe -fPIC” … The resulting make compile is $ make i686-pc-linux-gnu-gcc -fPIC -O2 -pipe -fPIC -I. -I/usr/lib/ruby/1.8/i686-linux -I/usr/lib/ruby/1.8/i686-linux -I. -c Vflow.c i686-pc-linux-gnu-gcc -shared -L’/usr/lib’ -Wl,-R’/usr/lib’ -o Vflow.so Vflow.o -Wl,-R -Wl,/usr/lib -L/usr/lib -L. -lruby18 -lft -lz -ldl -lcrypt -lm -lc /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.5-20050130/…/…/…/…/i686-pc- linux-gnu/bin/ld: warning: creating a DT\_TEXTREL in object. I’d seen the -FPIC thing in the few web pages I’d manage to find that mentioned this error. Unfortunately this doesn;t seem to fix the problem. I’m scratching my head over this one. gcc, glibc and ld have all been upgraded to the latest. gcc version 3.3.5-20050130 GNU ld version 2.16.1 This is on a gentoo box. I’ve also got access to a fedora core 5 box and the next chance I get I’ll be testing there to see if it’s a platform related problem. If anyone has any advise please speak up. Anyway, thanks for the suggestion Guy. Jeff. ---

This reply is more for future reference for anyone else that may stubble across this problem than anything else. Jeff.
