[Paraview] ParaView builds using Mesa

OK, I seem to have created a good build using fPIC and Mesa, and ParaView. The secret is as follows:
The error from a Paraview build says it is trying to relocate position dependent code. The normal way to create position independent code is with the -fPIC flag, passed into the CFLAGS and CXXFLAGS of Mesa, as presented in the previous e-mails. However, any inline assembler code in your libraries will also make it position dependent.
Thus, to compile Mesa, I did the following:
./configure --prefix=base-directory/Mesa-7.4.2-static --with-driver=xlib CFLAGS="-O -fPIC" CXXFLAGS="-O -fPIC" --disable-shared --disable-asm
make
make install
This then successfully made a version of ParaView.

Pat/All,
So, I tried compiling the static mesa libraries with fpic. Basically, I added the following to a special configs file:
CFLAGS = -O -fPIC
CXXFLAGS = -O -fPIC
PIC_FLAGS = -fPIC
CXX_PIC_FLAGS = -fPIC
Then, I CMake my paraview, with the following:
OPENGL_INCLUDE_DIR /projects/viz/paraview/support/Linux-cee-sw-rhel5-x86_64/install/Mesa-7.4.2-static/include
OPENGL_gl_LIBRARY /projects/viz/paraview/support/Linux-cee-sw-rhel5-x86_64/install/Mesa-7.4.2-static/lib/libMESAGL.a
OPENGL_glu_LIBRARY /projects/viz/paraview/support/Linux-cee-sw-rhel5-x86_64/install/Mesa-7.4.2-static/lib/libMESAGLU.a
OPENGL_xmesa_INCLUDE_DIR
OSMESA_INCLUDE_DIR /projects/viz/paraview/support/Linux-cee-sw-rhel5-x86_64/install/Mesa-7.4.2-static/include
OSMESA_LIBRARY /projects/viz/paraview/support/Linux-cee-sw-rhel5-x86_64/install/Mesa-7.4.2-static/lib/libMESAOSMesa.a
VTK_USE_MANGLED_MESA OFF
VTK_OPENGL_HAS_OSMESA OFF
And -it fails as follows:
inking CXX shared library ../../bin/libvtkRendering.so
/usr/bin/ld: /projects/viz/paraview/support/Linux-cee-sw-rhel5-x86_64/install/Me sa-7.4.2-static/lib/libMESAGL.a(glapi_x86-64.o): relocation R_X86_64_PC32 agains t `_glapi_Dispatch' can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: final link failed: Bad value
collect2: ld returned 1 exit status
make[2]: *** [bin/libvtkRendering.so.pv3.10] Error 1
make[1]: *** [VTK/Rendering/CMakeFiles/vtkRendering.dir/all] Error 2
make: *** [all] Error 2
Notice it is the correct version of mesa (I renamed libGL.a to libMESAGL.a, thus making sure that I am not picking up system versions of Mesa), and that it is still asking for fPIC.

Yes, I do have Python enabled. I see where shared libs gets turned on.
I will try to create fpic versions of static mesa, and if that doesn't work, try a dynamic build of ParaView (again).
Thanks.

Hi Alan,
Are you building with python enabled? If python is enabled then BUILD_SHARED_LIBS will turn itself on automatically.
Is there any reason you cannot compile mesa with shared libs, or compile mesa static with -fPIC?

I am trying to create a paraview (client side) build of ParaView using Mesa on Linux. I have compiled Mesa using Mesa 7.4.2, compiled with 'make linux-x86-64-static'.
I am now trying to compile ParaView, and keep failing with the following:

I have tried setting "BUILD_SHARED_LIBS" off when using ccmake on paraView, but it keeps turning itself on.
What I believe I need to do is create a static build of ParaView, thus Mesa won't need the -fPIC flag.
Any ideas?
Thanks all,
Alan
