[Plib-users] ./configure opengl problem

[McEvoy, N. <nic...@ds...>]

Ok so I decided to make the big switch from Windoze to Linux !  Its been something I've been wanting to do for ages ... so I decided to go with RedHat 8.0 ... well just because ... lets not get into a big discussion about this eh ! :)

Now that I've made the switch I want to get back into my games development hobby with plib & ode.

But I've hit a problem (already) trying to build plib-1.6.0 !

I have installed required software eg. opengl & glut3.7 ... but ./configure says "configure: error: could not find working GL library" ... whats going on ?

(nb. I installed XFree86-devel ... the RPM says it provides Mesa-devel ... I seem to have all the right libraries)

Any ideas ?

                  Why this?

It seems to be missing Pthreads (-lpthread)

Some versions of Mesa need it - and are not pre-linked with it...so
OpenGL applications under Linux are recommended to link to pthreads
even if they don't explicitly need it.

I've never seen this be a problem with ./configure though.

Does a straight "./configure" without the "--with-GL=/usr" work?

Known bug - the configure script does not link against the pthread library,
which is necessary for certain Mesa versions.

Didn't I intend to change that prior to the 1.6.0 release ? Hmm ... seems
like I did not.

Anyhow - for now, search for the following line in configure.in:

AC_CHECK_LIB(GL, glNewList)

.. and add this line prior to it:

AC_CHECK_LIB(pthread, pthread_create)


Then, while in the root of the plib source tree, run

/autogen.sh

and

/configure

(which should work flawlessly now).
