[SOLVED] libGLES related build errors

coralfang · 06-21-2014, 02:38 AM

Keep getting this odd problem, i've installed the proprietary nvidia driver on slackware64, some things are failing to build when it requires libGLES...

slackbuild for "minetest" failing:

Code:

[ 99%] Building CXX object src/CMakeFiles/minetest.dir/version.cpp.o
[ 99%] Building CXX object src/CMakeFiles/minetest.dir/voxel.cpp.o

make[2]: *** [../bin/minetest] Error 1
make[1]: *** [src/CMakeFiles/minetest.dir/all] Error 2
make: *** [all] Error 2

I noticed this:

Code:

# ls -l /usr/lib/libGLESv2.so
lrwxrwxrwx 1 root root 14 Jun 21 05:57 /usr/lib/libGLESv2.so -> libGLESv2.so.2*
# ls -l /usr/lib/libGLESv2.so.2

/usr/lib/libGLESv2.so.331.79: ELF 32-bit LSB  shared object, Intel 80386, version 1 (SYSV), dynamically linked, stripped

Why is it trying to include a 32bit library? And how can i get this to build. Thanks..

reinstall stock mesa package

You don't say, but my guess is that you installed the nvidia stuff using the nvidia installer, not the SBo SlackBuild.

The SBo SlackBuild only installs 32 bit compatibility libraries if you request them. But IIRC the nvidia installer always installs them, including in particular the 32-bit-only libGLESv2 shared library that is causing your problem. The SBo minetest SlackBuild builds fine without OpenGL ES:

Code:

[ 99%] Building CXX object src/CMakeFiles/minetest.dir/voxel.cpp.o
[100%] Building CXX object src/CMakeFiles/minetest.dir/voxelalgorithms.cpp.o
Linking CXX executable ../../bin/minetest
[100%] Built target minetest
[  0%] Built target jsoncpp
[  0%] Built target GenerateVersion
[ 43%] Built target minetestserver
[100%] Built target minetest
Install the project...
-- Install configuration: "Release"
-- Installing: /tmp/SBo/package-minetest/usr/share/minetest/builtin
-- Installing: /tmp/SBo/package-minetest/usr/share/minetest/builtin/item_entity.lua

So uninstall the nvidia stuff completely, and then install it using the SBo SlackBuild.

Thanks guys, i will try that out soon.

*reinstall mesa
*reinstall nvidia (from slackbuilds)

I did install the driver using nvidia's installer directly (done that for many years) and not until recently have i used multilib on slackware, so that must be causing the conflict.

Cheers!

EDIT: just did it now, its working

Hello,

If you don't need 32-bit compatibility libraries you can download the official no-compat32 package from nvidia's ftp server. For instance, for latest long lived branch at ftp://download.nvidia.com/XFree86/Linux-x86_64/331.79 :

Code:

$ lftp -c "open ftp://download.nvidia.com/XFree86/Linux-x86_64/331.79/ ; ls"
