GL librairy as disappeared

[c4ctusal]

I installed the drivers successfully on Mandrake 9.0, but when I tried to compile some app that uses OpenGL I had the following in KDevelop: " libtool: link: cannot find the library `/usr/X11R6/lib/libGL.la' "

I search for the file libGL.la but it no longer exists on my system. I'm sure this happened because of the driver installation because this application compiled without errors just before I installed the driver. (I installed because it was too slow :) )

Thanks for your help !

What command is the program you're using executing to link itself? i.e. what does make print out, from outside KDevelop? Am I correct in assuming that even works?

Programs should not be looking for libGL.so (which libGL.la is just a text-file wrapper around) in any hardcoded location, especially not /usr/X11R6/lib.

You can try creating a libGL.la file in /usr/lib, though. Make it look like this:

# libGL.la - a libtool library file
# Generated by ltmain.sh - GNU libtool 1.3.5 (1.385.2.206 2000/05/27 11:12:27)
#
# Please DO NOT delete this file!
# It is necessary for linking the library.

# The name that we can dlopen(3).
dlname=''

# Names of this library.
library_names='libGL.so.1.0.3123 libGL.so.1 libGL.so'

# Libraries that this one depends upon.
dependency_libs=' -lm -lXext -lX11 -ldl -L/usr/X11R6/lib'

# Version information for libGL.
current=1
age=0
revision=3123

# Is this an already installed library?
installed=yes

# Directory that this library needs to be installed in:
libdir='/usr/lib'

Try creating the libGL.la file, as outlined above. See if that helps.

[c4ctusal]

I copied libGL.la in /usr/X11R6/lib and it worked.

However, I don't understand why this file can't be located in /usr/lib. Isn't it supposed to search in all lib directories. Well, I'm new to Linux so I may discover this with time.

Thanks for your help bwkaz

[bwkaz]

Yes, it is supposed to look all over. I think it has something to do with libtool being weird, but I don't know why.

Hmm, whatever.

Hi,

I'm using mandrake 10 with kernel 2.6.3-4 with the latest drivers (5336) provided by nvidia. While I tried to compile digikam I fell on the same problem :

/bin/sh ../libtool --silent --mode=link --tag=CXX g++

-Wchar-subscripts -O2 -Wformat-security
-Wmissing-format-attribute -fno-exceptions -fno-check-new

-fno-common -DQT_CLEAN_NAMESPACE -o

The /usr/X11R6/lib/libGL.la as move out to /usr/lib/libGL.la and a simple symlink solve the problem.
