How to check if compiled/installed apache has posix threads library?

Have an installation of apache in one box which I want to confirm if it is configured with both threads and fork libraries. how do i check?

To check use ldd to see the libraries it is linked against for the rest of the question no clue.

ldd /usr/sbin/apache
        libm.so.6 => /lib/libm.so.6 (0x00002b7894113000)
        libpthread.so.0 => /lib/libpthread.so.0 (0x00002b7894395000)     <------------------
        libcrypt.so.1 => /lib/libcrypt.so.1 (0x00002b78945b0000)
        libdb-4.4.so => /usr/lib/libdb-4.4.so (0x00002b78947e4000)
        libexpat.so.1 => /usr/lib/libexpat.so.1 (0x00002b78949ec000)
        libdl.so.2 => /lib/libdl.so.2 (0x00002b7894b0e000)
        libc.so.6 => /lib/libc.so.6 (0x00002b7894d12000)
        /lib64/ld-linux-x86-64.so.2 (0x00002b7893ef6000)

so if it is linked to libpthread, apache is configured to run as threaded?

You should run:

httpd -V

to check if your apache was compiled with threads and fork.

ahh cool

so mine says
-D APACHE_MPM_DIR="server/mpm/prefork" and
-D APR_USE_PTHREAD_SERIALIZE

that refers to threading and forking yah?

Nope, you should also see something like:

Server MPM:     Worker
  threaded:     yes (fixed thread count)
    forked:     yes (variable process count)
