[Mesa-users] OpenGL 3.2 with SWR?

[Chuck Atkins]

What does the end of your configure output look like?  You should see a
summary at the end of configure.  I suspect you may be missing some
dependent library.  On Fedora, I typically build a stripped down mesa that
only contains llvmpipe and swr for both GL and OSMesa.  My build looks like
this:

First I apply the following patch to src/mesa/Makefile.am to prevent a bug
in the auto-make scripts that install conflicting libgl versions for BOTH
dri and gallium.  Note, there may be a better way to patch this bug but
patches posted to the dev list were ignored and this way seems to work at
least:
-- a/src/mesa/Makefile.am
+++ b/src/mesa/Makefile.am
@@ -22,8 +22,10 @@
 SUBDIRS = . main/tests

 if HAVE_X11_DRIVER
+if !HAVE_GALLIUM
 SUBDIRS += drivers/x11
 endif
+endif

 if HAVE_DRICOMMON
 SUBDIRS += drivers/dri

Then I configure with:
./autogen.sh \
  --disable-va --disable-gbm --disable-xvmc --disable-vdpau \
  --disable-dri --with-dri-drivers= \
  --disable-egl --with-egl-platforms= --disable-gles1 --disable-gles2 \
  --enable-texture-float \
  --enable-glx --enable-xlib-glx \
  --enable-gallium-llvm=yes --enable-gallium-osmesa \
  --with-gallium-drivers=swrast,swr \
  --prefix=/path/to/install

My output looks like (specifically note the "Gallium drivers:" line):

        PYTHON2:         python2.7

        Run 'make' to build Mesa


Then I make -j8 install.  The resulting install then has the following
libraries:

libglapi.la
libglapi.so -> libglapi.so.0.0.0
libglapi.so.0 -> libglapi.so.0.0.0
libglapi.so.0.0.0
libGL.la
libGL.so -> libGL.so.1.5.0
libGL.so.1 -> libGL.so.1.5.0
libGL.so.1.5.0
libOSMesa.la
libOSMesa.so -> libOSMesa.so.8.0.0
libOSMesa.so.8 -> libOSMesa.so.8.0.0
libOSMesa.so.8.0.0
libswrAVX2.la
libswrAVX2.so -> libswrAVX2.so.0.0.0
libswrAVX2.so.0 -> libswrAVX2.so.0.0.0
libswrAVX2.so.0.0.0
libswrAVX.la
libswrAVX.so -> libswrAVX.so.0.0.0
libswrAVX.so.0 -> libswrAVX.so.0.0.0
libswrAVX.so.0.0.0

Does your build produce similar output?
