Обсуждение: BUG #2436: cannot --enable-thread-safety on -lpthread host
The following bug has been logged online: Bug reference: 2436 Logged by: Paul Forgey Email address: paulf@aphrodite.com PostgreSQL version: 8.1.3 Operating system: Debian stable (sarge) Description: cannot --enable-thread-safety on -lpthread host Details: Linux supplies -lpthread. The configure script seems to only look for -lpthreads and then give up. I'm surprised to not find anything about this on the mailing list archives. configure:16421: checking for the pthreads library -lpthreads configure:16459: gcc -o conftest -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Winline -Wendif-labels -fno-strict-aliasing -D_GNU_SOURCE conftest.c -lpth reads -lz -lreadline -lcrypt -lresolv -lnsl -ldl -lm >&5 conftest.c: In function `main': conftest.c:124: warning: `th' might be used uninitialized in this function /usr/bin/ld: cannot find -lpthreads collect2: ld returned 1 exit status configure:16465: $? = 1

Say again? I get this configure trace on Fedora 4:
checking for the pthreads library -lpthreads... no
checking whether pthreads work without any flags... no
checking whether pthreads work with -Kthread... no
checking whether pthreads work with -kthread... no
checking for the pthreads library -llthread... no
checking whether pthreads work with -pthread... yes
checking whether pthreads work with -pthreads... no
checking whether pthreads work with -mthreads... no
checking for the pthreads library -lpthread... yes
checking whether pthreads work with --thread-safe... no
checking whether pthreads work with -mt... no
checking for the pthreads library -lpthreadGC2... no
checking pthread.h usability... yes
checking pthread.h presence... yes
checking for pthread.h... yes

The point is that the configure script clearly does test for -lpthread,
so whatever problem you're having, you've not described it correctly.

As given in my OS info, this isn't FC4. The configure script fails to enable threading in Debian Sarge.
