Status: Open
Bug Type: Compile Failure
Operating System: FreeBSD
PHP Version: 5.0.3
New Comment:
-pthread is not: a) library b) libpath
As such, it will not be handled by PHP_EVAL_LIBLINE.

Description:
------------
It looks like FreeBSD uses gcc's -pthread switch to specify whether or
not something should be linked against a POSIX Threading Library
(libpthread|libthr|libc_r) ...
This is apparent e.g. when building libxml2 the generated xml2-config
utility (which is used by PHPs build system) gives the following
outputfor the --libs target
-L/usr/local/lib -lxml2 -lz -pthread -L/usr/local/lib -liconv -lm
As far as i can tell this data is processed in the PHP_EVAL_LIBLINE
m4-macro contained in PHP's acinclude.m4 (passed from
ext/xml/config.m4)
And as far as i can tell from the generated configure script it seems
to only handle the -l* and -L* entries.
This causes the configure phase for every php-extension that uses
-pthread in its library definitions to fail because of missing
pthread_* symbols.
Reproduce code:
---------------
Simply try to build any php5-extension module that depends on libxml2
where libxml2 is build with threads-support.
Expected result:
----------------
I expect the configure phase to complete successfully.
Actual result:
--------------
configure:2643: checking whether libxml build works
configure:2672: cc -o conftest -O2 -fno-strict-aliasing -pipe
-march=pentium2
conftest.c
-R/usr/local/lib -L/usr/local/lib -R/usr/local/lib
-L/usr/local/lib -lxml2 -lz -liconv -lm
>&5

return 0;
}
