make: *** [all] Error 2

To reproduce:

1. Apply switch to dynamic gmmlib media-driver#270
2. Try to configure and build media driver - you will see the above link error

Detailed repro steps:

git clone https://github.com/intel/media-driver.git && cd media-driver
git fetch origin pull/270/head:gmmlib_via_pkgconfig
git checkout gmmlib_via_pkgconfig
export PKG_CONFIG_PATH=/path/to/gmmlib/install/location/pkgconfig/igdgmm.pc
mkdir build && cd build
cmake ..
make -j8

[drprajap]

parts of the fix should come from intel/media-driver which will remove references to C-wrappers interfaces -these interfaces are no longer exported in dynamic lib. media-driver to switch to ClientContext and appropriate exported c++ class members.

GmmLib will address the issue with inlined exported APIs and update the issue.

[drprajap]

GmmLib fix has been merged - 173b246 to address issue with inline'd exported APIs

[dvrogozh]

@drprajap : gmmlib part is addressed in 173b246. Should we close this issue? We are tracking media-driver part in intel/media-driver#246, intel/media-driver#35 and a fix candidate is in intel/media-driver#270

[drprajap]

yes. we should close this issue.
