Platform Specific Build Instructions

Building with GCC

When the library is built using GCC it is necessary to link with the pthread library due to how GCC implements std::thread. Failing to link to pthread will lead to runtime exceptions (unless you're using libc++), not linker errors. See issue #67 for more details. You can link to pthread by adding -pthread to your linker command. Note, you can also use -lpthread, but there are potential issues with ordering of command line parameters if you use that.

On QNX, the pthread library is part of libc and usually included automatically (see pthread_create()). There's no separate pthread library to link.

Building with Visual Studio 2015 or 2017

The shlwapi library (-lshlwapi) is required to support a call to CPUInfo which reads the registry. Either add shlwapi.lib under [ Configuration Properties > Linker > Input ], or use the following:

// Alternatively, can add libraries using linker options. #ifdef _WIN32 #pragma comment ( lib, "Shlwapi.lib" ) #ifdef _DEBUG #pragma comment ( lib, "benchmarkd.lib" ) #else #pragma comment ( lib, "benchmark.lib" ) #endif #endif

Can also use the graphical version of CMake:

  • Open CMake GUI.
  • Under Where to build the binaries, same path as source plus build.
  • Under CMAKE_INSTALL_PREFIX, same path as source plus install.
  • Click Configure, Generate, Open Project.
  • If build fails, try deleting entire directory and starting again, or unticking options to build less.

Building with Intel 2015 Update 1 or Intel System Studio Update 4

See instructions for building with Visual Studio. Once built, right click on the solution and change the build to Intel.

Building on Solaris

If you're running benchmarks on solaris, you'll want the kstat library linked in too (-lkstat).
