This file contains notes for making distribution packages of pocl. | |
ICD | |
--- | |
Pocl should probably be built with ICD enabled (``-DENABLE_ICD=ON`` CMake | |
option) for desktop distributions. Pocl does not have an ICD loader, | |
so a dependancy on one would be beneficial. | |
CMake options for a distribution build | |
-------------------------------------- | |
- ``-DKERNELLIB_HOST_CPU_VARIANTS=distro`` | |
Note: this note only works for x86(-64) platform currently, | |
on other platforms, it has zero effect. | |
Enables runtime detection of CPU and builds separate | |
kernel libraries for most common x86 CPUs. | |
- ``-DPOCL_ICD_ABSOLUTE_PATH=OFF`` | |
The pocl.icd file (which the ICD loader uses to load the pocl lib) | |
by default has a full path to the installed libpocl.so file. | |
Set this option to OFF and pocl will only put the dynamic library | |
name into pocl.icd. | |
- ``-DENABLE_POCL_BUILDING=OFF`` | |
When OFF, POCL_BUILDING option (which causes pocl to look for required | |
files in build / source directories) will be ignored | |
and pocl will always look in installed paths only. | |
Mesa (OpenGL) interoperability | |
------------------------------ | |
On some current (Jan 2014) Linux distibutions, mesa is built with LLVMpipe. | |
If pocl is built against a shared LLVM library, the mesa calls to its LLVM | |
will be re-routed to the LLVM linked in pocl, causing a segfault. Consider | |
linking LLVM statically to pocl. At least 'nouveau' and 'swrast_dri' are | |
known to suffer from this. See https://github.com/pocl/pocl/issues/46 |
