            Bug ID: 94086
           Summary: Multiple conflicting libGL libraries installed
           Product: Mesa
           Version: git
          Hardware: All
                OS: All
            Status: NEW
          Severity: minor
          Priority: medium
         Component: GLX
          Assignee: mesa-dev at lists.freedesktop.org

When enabling Gallium and glx-xlib with autotools, both a "classic mesa"
libGL.so.1.6.0 and a gallium libGL.so.1.5.0 get built and installed.  Using the
following configuration for software-only backends:

$ ./configure \
  --disable-va \
  --disable-gbm \
  --disable-xvmc \
  --disable-vdpau \
  --disable-dri \
  --with-dri-drivers= \
  --disable-egl \
  --with-egl-platforms= \
  --disable-gles1 \
  --disable-gles2 \
  --disable-shared-glapi \
  --disable-llvm-shared-libs \
  --enable-texture-float \
  --enable-glx \
  --enable-xlib-glx \
  --enable-gallium-llvm=yes \
  --enable-gallium-osmesa \
  --with-gallium-drivers=swrast \
  --prefix=/path/to/install
...
$ make
...
$ make install
..e
$ ls -l /path/to/install
libGL.la
libGL.so -> libGL.so.1.5.0
libGL.so.1 -> libGL.so.1.6.0
libGL.so.1.5.0
libGL.so.1.6.0
libOSMesa.la
libOSMesa.so -> libOSMesa.so.8.0.0
libOSMesa.so.8 -> libOSMesa.so.8.0.0
libOSMesa.so.8.0.0
pkgconfig

The following patch disables the 1.6.0 lib if gallium is enabled:

$ git diff
diff --git a/src/mesa/Makefile.am b/src/mesa/Makefile.am
