configure tells me I don't have pthread

I am trying to install a snort monitor and when I run configure I get this error:

Code:

checking for pthread_create in -lpthread... no
checking for pthread_create in -lpthreads... no
checking for pthread_create in -lc_r... no
checking for pthread_create... no
Error: Pthread is required to build this package.

The problem is that I have pthread. I have even used it myself when programming. I have checked my ld.so.conf so it points to the directions I get when I do this:

Code:

$ locate libpthread              
/lib/libpthread-0.10.so
/lib/libpthread.so.0
/usr/lib/libpthread.so
/usr/lib/libpthread_nonshared.a
/usr/lib/libpthread.a

What is the problem now? I am able to compile my own programs with g++ just using the -lpthread switch. And I am using the pthread_create function without problems. What is configure complaining about?

i don't really know what that is but have seen other people talking about it

it may have something to do with optimizations or something
more likelly just a minor conflict in versions of something or a bug in pthread or gcc or libtool or whatever

i think it would be perfectly safe to just hack the configure script and make it so it always thinks those tests worked (returned 0)

Haha, nice. But one problem, I don't know how to hack configure. I have not yet explored the autotools-world as much as I should. :P

objdump -R /usr/lib/libgthread-2.0.so.0 | grep pthread_create

that's probably the pthread_create your finding when you compile your own stuff ( even if it's not in libpthread ( which it wasn't on my slack 10 using objdump) the linker will find it if it's in the lib path when you compile your own apps)
