The pkg-config tool is widely used to simplify building software with library dependencies. It provides command line options for compiling and linking applications to a library.

Set up the environment

Set up the environment before using the pkg-config tool. To do this, use one of the following options:

  • Intel(R) oneAPI Base Toolkit script

  • oneVPL script.

For example, you may use on of the following for a Linux install to the standard /opt/intel/oneapi locations:

  • source /opt/intel/oneapi/
  • source /opt/intel/oneapi/vpl/latest/env/

Compile a program using pkg-config

For example, to compile a test program test.cpp with oneVPL, you could provide the full path to search for include files and libraries, or you could provide a simple line like this:

g++ test.cpp `pkg-config --cflags --libs vpl`

--cflags provides the include path to the API directory:

pkg-config --cflags vpl

The result:

-I/opt/intel/oneapi/vpl/2021.4.0/lib/pkgconfig/../..//include -I/opt/intel/oneapi/vpl/2021.4.0/lib/pkgconfig/../..//include/vpl

--libs provides the oneVPL library name and the search path to find it:

pkg-config --libs vpl

The result:

-L/opt/intel/oneapi/vpl/2021.4.0/lib/pkgconfig/../..//lib -lvpl

The pkg-config tool helps avoid large hard-coded paths and makes compilation more portable.
