#Cmake install use environment variables windows
Īlternatively, use the ccmake text-based interface or the CMake app GUI.Quick steps for OpenSceneGraph installation in Windows With CMake, options are specified on the command line using -Doption=value syntax (not as environment variables), such as: # in build directoryĬmake -Dbuild_tests=no -DCMAKE_INSTALL_PREFIX=/usr/local. Particularly, DEBUG or TRACE gives useful information. In ascending order:įATAL_ERROR, SEND_ERROR, WARNING, AUTHOR_WARNING, DEPRECATION, MinSizeRel Release, but optimized for size (-Os -DNDEBUG) RelWithDebInfo optimized, no asserts, with debug info (-O2 -DNDEBUG -g) Release optimized, no asserts, no debug info (-O3 -DNDEBUG) default compiler optimization (no flags)ĭebug no optimization, with asserts (-O0 -g) Where to look for CMake packages such as BLAS++ and TestSweeper. Whether to build as a static or shared library. Standard CMake options include: BUILD_SHARED_LIBS Use CMake's FindLAPACK, instead of LAPACK++ search. If BLA_VENDOR is set, it automatically uses CMake's FindLAPACK. There is usually no need to specify this. Whether to use CMake's FindLAPACK, instead of LAPACK++ search.Īgain, as LAPACK is often included in the BLAS library, Requires TestSweeper, CBLAS, and LAPACKE. Whether to build test suite (test/tester). īesides the Environment variables and Options listed above, additional options include: build_tests cmake -Dtestsweeper_DIR=/path/to/testsweeper/build. To use a different TestSweeper build that was not installed, you can point to its directory. If CMake doesn't find TestSweeper, it will be downloaded and compiled. LAPACK++ uses the TestSweeper library ( ) to run its tests. Ĭmake -Dblaspp_DIR=/path/to/install/lib/blaspp. If LAPACK++ can't find BLAS++, you can point to its directory: cmake -DCMAKE_PREFIX_PATH=/path/to/install.
#Cmake install use environment variables install
LAPACK++ should find BLAS++ if it is installed in a system default location (e.g., /usr/local), or their install prefix is the same. Create a build directory under the LAPACK++ root directory: # After installing BLAS++ above The CMake script enforces an out-of-source build. Briefly: # LAPACK++ requires BLAS++, fromĬmake. Information and installation instructions can be found at. LAPACK++ requires BLAS++ and inherits its dependencies from BLAS++, so BLAS++ must be installed first via CMake, before running CMake for LAPACK++. All test files are in the config directory. The log shows the option being tested, the exact command run, the command's standard output (stdout), error output (stderr), and exit status. If you experience unexpected problems, please see config/log.txt to diagnose the issue. Note that all test programs are compiled with those options, so errors may cause configure to fail. LIBS="-lmkl_gf_lp64 -lmkl_gnu_thread -lmkl_core -lm" Make install - installs the library and headers to \f$/lib/intel64 -fopenmp" \ Make docs - generates documentation in docs/html/index.html Make check - run basic checks using tester Make lib - compiles the library (lib/liblapackpp.so) Make config - configures LAPACK++, creating a make.inc file Īvailable targets: make - configures (if make.inc is missing), With CMake, options are specified on the command line using -Doption=value syntax (not as environment variables), such as: cmake -Dblas=mkl. With Makefile, options are specified as environment variables or on the command line using option=value syntax, such as: python configure.py lapack=generic (default with Makefile not support with CMake) Specify the exact LAPACK libraries, overriding the built-in search.Īgain, there is usually no need to specify this. So there is usually no need to specify this. LAPACK is often included in the BLAS library (e.g., -lopenblas contains both), LAPACK++ specific options include (all values are case insensitive): lapack Since the LAPACK library is often bundled with the BLAS library, such as -lopenblas, it should be specified in BLAS++. See the BLAS++ INSTALL.md for BLAS++ specific options. LD_LIBRARY_PATH runtime library search pathĭYLD_LIBRARY_PATH runtime library search path on macOS LIBRARY_PATH compile-time library search path Standard environment variables affect both Makefile (configure.py) and CMake. Option 2: CMake # LAPACK++ requires BLAS++, fromĮnvironment variables (Makefile and CMake) Configure and compile the LAPACK++ library and its tester, then install the headers and library.
