[ruby-core:28376] [Bug #2826] pthreads compilation failure on Solaris

From: Fabian Groffen <redmine@...>
Date: 2010-02-28 13:12:30 UTC
List: ruby-core #28376
Bug #2826: pthreads compilation failure on Solaris
http://redmine.ruby-lang.org/issues/show/2826

Author: Fabian Groffen
Status: Open, Priority: Normal
ruby -v: ruby 1.8.7 (2010-01-10 patchlevel 249) [i386-solaris2.10]

Original bug:
http://bugs.gentoo.org/show_bug.cgi?id=307159

Ruby's configure tries to find the right way to link against pthread libs by itself.  This fails amongst others on Solaris.  GCC itself knows fairly well how to link against pthreads libs using -pthread.  The original error on Solaris is:

i386-pc-solaris2.10-gcc -shared -o ../../.ext/i386-solaris2.10/bigdecimal.so
bigdecimal.o -L. -L../.. -L.  -Wl,-E    -Wl,-R
-Wl,/nilfisk/home/dve/gentoo-new/usr/lib -L/nilfisk/home/dve/gentoo-new/usr/lib
-lruby18  -lpthread -lrt -ldl -lcrypt -lm   -lc
/nilfisk/home/dve/gentoo-new/usr/lib/gcc/i386-pc-solaris2.10/4.4.3/../../../../i386-pc-solaris2.10/bin/ld:
../../libruby18.so: pthread_mutex_unlock: invalid version 2 (max 0)
../../libruby18.so: could not read symbols: Bad value
collect2: ld returned 1 exit status
make[1]: *** [../../.ext/i386-solaris2.10/bigdecimal.so] Error 1

When -lpthread is replaced by -pthread (hence letting GCC inject the right linker arguments -- and in the correct order) this compiles fine.  I created a patch to configure.in for this, but it is quite hacky, and only serves as an indication.

I tested that this patch does not break compilation on Darwin (10.4/ppc).  I think the ideal solution would be to use something like ax_pthread (http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob;f=m4/ax_pthread.m4;h=37502dd83abe789d2287418f9ed10fd24c21b314;hb=7a6c511965489c38f5d3bef4afe113e3fe11c2ac) which contains all the gory logic to find the right argument to link against pthread libs.
