[Plib-devel] plib 1.8.5 won't pass the autoconf phase in Ubuntu Gutsy

[Anton G. <gal...@gm...>]

Hi there,

I'm having problems to build plib 1.8.5 from sources due to a problem in
autoconf. This is an Ubuntu Gutsy Linux distro with proper Mesa GL and
pthreads installation. This is how the error looks from the outside:

===============================
...
checking for pthread_create in -lpthread... no
checking for glNewList in -lGL... no
checking for glNewList in -lMesaGL... no
configure: error: could not find working GL library
...
===============================

And this is how it looks from config.log:

===============================
configure:6287: checking for pthread_create in -lpthread
configure:6322: gcc -o conftest -g -O2    conftest.c -lpthread    -lSM -lICE
-lXi -lXmu -lXext -lX11  -lm >&5
/usr/bin/ld: cannot find -lXi
collect2: ld returned 1 exit status
configure:6328: $? = 1
configure: failed program was:

| /* end confdefs.h.  */

| /* Override any GCC internal prototype to avoid an error.

===============================

The problem in this installation was libxi-dev and libxmu-dev packages where
not installed. But also, by replacing line 279 in config.in
        LIBS="$LIBS $X_PRE_LIBS -lXi -lXmu -lXext -lX11 $X_EXTRA_LIBS -lm"

to something like this:
        LIBS="$LIBS $X_PRE_LIBS $X_LIBS $X_EXTRA_LIBS -lm"

The compilation went smooth as silk. Maybe those libs are not really needed?

Kind regards,

Anton
