[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:

| #define PACKAGE_NAME ""
| #define PACKAGE_TARNAME ""

| #define PACKAGE "plib"
| #define VERSION "1.8.5"
| /* end confdefs.h.  */
|
| /* Override any GCC internal prototype to avoid an error.

| #ifdef __cplusplus

| #endif
| char pthread_create ();
| int
| main ()
| {
| return pthread_create ();
|   ;
|   return 0;

configure:6346: result: no

| char glNewList ();
| int
| main ()
| {
| return glNewList ();
|   ;
|   return 0;
| }
configure:6417: result: no
===============================

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

Anton,

	Does the PLIB that you build without the X libraries link
properly with a sample program?  PLIB itself is just a library and
doesn't really need a final link step where everything must be defined;
the real test of when libraries are needed comes in building an
application.

Hi,

on my Ubuntu Gutsy box, configure && make works without any trouble:

  checking for pthread_create in -lpthread... yes
  checking for glNewList in -lGL... yes

But I can recall that I experienced similar problems when I compiled
CRRCsim on Gutsy for the first time. I then decided to remove these
libs from the (very old) Makefiles and never really missed them.

Kind regards,
Jan R.

PS: By the way, configure && make and the examples also work fine on
    Windows XP (using MinGW & MSYS).

PPS: The SourceForge project page (http://sourceforge.net/projects/plib/)
     still shows 1.8.5-rc1 as the most recent release.
