Bug 147585 – dev-db/libpq-8.1.4 fails to build with 'threads' use flag

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description Maciej Grela 2006-09-14 10:07:13 UTC]

I`ve encountered a problem trying to emerge libpq-8.1.4 (from the experimental ~x86 branch).

# ACCEPT_KEYWORDS="~x86" emerge libpq

....

checking thread safety of required library functions... no
configure: error:
*** Thread test program failed.  Your platform is not thread-safe.
*** Check the file 'config.log'for the exact reason.
***
*** You can use the configure option --enable-thread-safety-force
*** to force threads to be enabled.  However, you must then run
*** the program in src/tools/thread and add locking function calls
*** to your applications to guarantee thread safety.


!!! ERROR: dev-db/libpq-8.1.4 failed.

In config.log we find:

It looks like the configure script doesn`t add -lpthread to the compiler invocation causing a link error. I`d try to fix it myself, but unfortunately my knowledge of autoconf is not sufficient.
