Default libGLcore removed during installation

During installation of the nvidia drivers on my
debian system (XFree 4.3.0) the GLcore module is removed by the installer.

I can restore the file from my backups, but then there are warning messages in the XFree log file.


(II) Loading /usr/X11R6/lib/modules/extensions/libGLcore.a
Skipping "/usr/X11R6/lib/modules/extensions/libGLcore.a:m_debug_clip.o": No symbols found

I really think libGLcore.a exists in the directory it says it is in. And also remove the line: Load "GLcore" from your XF86Config file ...

The file exists, because I restored it from my backups. During installation it had been removed by the installer.

Why should I remove the GLcore line?

libGLcore.a is not part of the nvidia drivers. If the file exists, that Load-line loads it. When the file is removed X might try to load libGLcore.so which also is not an X module ..

libGLcore.a is part of DRI.

libGLcore.so (in /usr/lib) is from the nVidia drivers.

You need the second, not the first.

/usr/lib/libGLcore.so is not a module, which can be loaded at the start of X.

Is there a loadable module from the nVidia drivers, which can be included into XF86Config-4 ?

Section "Module"
Load "GLcore"

The only module for the nvidia drivers that needs to be in the module section is "glx" for the rest nothing, really no GLcore in it ..

You should only be loading GLcore if you use DRI.

The libglx.so X module does link against /usr/lib/libGLcore.so (unless you do like you're doing, and Load "GLcore", then it gets all screwed up), in order for it to have an interface to the hardware, but it's not an X module (as you've seen), and should not be loaded as such.

bwkaz and Thunderbird:

thank you very much for your answers! I begin to understand...

Greetings,
Martin

(PS: I still feel uncomfortable, if an installer removes files without warning...).

If you run the installer with the -e switch (or --expert), it'll ask a lot more questions. One of them will be "this is what I'm about to do. Is this OK?"

Of course, that doesn't tell you what the files are, but it does at least ask before it blows things away. Oh, and on that screen, when it says "back up <some file>", it only means back it up until the installer's done, then blowing away the backup. At least, after I was done with the installer, none of those files existed anywhere, backed up or not.
