Compiling with OpenMP

Compiling with OpenMP#
Some of Vapor’s libraries have been optimized with the OpenMP API. To build Vapor with these optimizations, ensure that your compiler supports OpenMP, and enable the following flags through ccmake,or by passing the arguments into cmake.
Our team builds Vapor with OpenMP with LLVM 13+ and GCC 4.2+.
Manually setting flags with ccmake#
To generate an optimized release build with OpenMP, set the following fields with ccmake.
CPACK_BINARY_DRAGNDROP |
ON |
CMAKE_BUILD_TYPE |
Release |
DIST_INSTALLER |
ON |
CMAKE_CXX_COMPILER |
/path/to/your/c++/compiler |
CMAKE_C_COMPILER |
/path/to/your/c/compiler |
USE_OMP |
ON |
Command line CMake build incantation#
Alternatively, cmake can apply these arguments through command-line arguments as follows:
cmake \
-DCPACK_BINARY_DRAGNDROP=ON \
-DCMAKE_BUILD_TYPE:String=Release \
-DDIST_INSTALLER:string=ON \
-DCMAKE_CXX_COMPILER=/opt/local/bin/clang++ \
-DCMAKE_C_COMPILER=/opt/local/bin/clang \
-DUSE_OMP=ON .. \
&& make \
&& make installer \
