Building SpecMiCP
-----------------
SpecMiCP uses CMake[1] as build system, to build it, in the specmicp directory, run :
cmake .
make
To customize build, see the cmake documentation[2] and the following informations :
Requirements :
==============
- C++11 compiler ( tested with
- gcc 4,9.2, 5.3.0 and 5.4.0
- clang 3.6.0. 3.7.0
- not tested with Visual Studio or others, probably won't work out of the box
- Eigen [4] (>=3.2, 3.3 branch is recommended)
- yaml-cpp [8] (>= 0.5) (version <= 0.5.1 requires boost)
- hdf5 (>=1.8 recommended, only the C serial API is used)
Older version required boost, but the dependancy has been removed. It may still be needed for old version of yaml-cpp.
Build the project requires CMake (Version >= 3.2)
Requirements for the documentation :
------------------------------------
- Doxygen[5]
The tests require Catch[6] but it is downloaded automatically by Cmake in the
project directory if needed (Header-only library).
Configuration Options :
=======================
These options are used by CMake to configure the project
- SPECMICP_NO_DEBUG
- bool (default OFF)
- if true, remove assert used in specmicp
- SPECMICP_USE_OPENMP :
- bool (default ON)
- use OpenMP to parallelize code
- SPECMICP_BUILD_STATIC
- bool (default OFF)
- if ON, also build static libraries. Note the static libraries are also
compiled with -fPIC so they can be used in python modules.
- SPECMICP_BINARIES_USE_STATIC
- bool (default OFF)
- if ON, executables use the static libraries
- SPECMICP_BUILD_EXAMPLE
- bool (default ON)
- if ON, build the examples
- SPECMICP_BUILD_BENCHMARK
- bool (default OFF)
- if ON, build the micro-benchmark, use Google benchmark library [9]
- SPECMICP_BUILD_TEST
- bool (default ON)
- if ON, build the test (run with ctest)
- SPECMICP_CXX_STANDARD_14
- bool (default OFF)
- If ON, compiles SpecMiCP using c++14
- SPECMICP_LTO
- bool (default OFF)
- if ON, use link-time optimization if available
- SPECMICP_LD_GOLD
- bool (default ON)
- if ON, use the Gold linker [7] if available
- SPECMICP_PROFILE_GENERATE
- bool (default OFF)
- if ON, generate the profiles for profile guided optimization
- SPECMICP_PROFILE_USE
- bool (default OFF)
- if ON, use the profiles to better optimimize the programs
The libs must have been compiled with -DSPECMICP_PROFILE_GENERATE=ON before,
and trained. See scripts/pgo_sequence.sh
- SPECMICP_DEBUG_EQUATION_FD_JACOBIAN
- bool (default OFF)
- Use a finite difference jacobian in specmicp. Thi sis a dev option only
as it is quite slower.
Examples of configuration :
mkdir build; cd build
cmake .. -DSPECMICP_USE_OPENMP=ON -DCMAKE_BUILD_TYPE=Release
Other example :
to install specmicp in '/opt/local'
mkdir build
cd build
cmake .. -DSPECMICP_BUILD_EXAMPLE=ON -DSPECMICP_USE_LTO=ON -DSPECMICP_USE_OPENMP=ON -DCMAKE_INSTALL_PREFIX=/opt/local -DCMAKE_BUILD_TYPE=release
make && make doc_html
make install
For a custom version of eigen 3:
-DEIGEN3_INCLUDE_DIR=[eigen3 directory]
This should not needed anymore, just for old version of yaml-cpp
For a custom version of boost :
-DBoost_NO_BOOST_CMAKE=true -DBOOSTROOT=[boost directory]
Tests
=====
The tests can be executed with through the ctest command
ctest [--output-on-failure]
ctest is part of the cmake framework. See the cmake documentation for help.
The commands `make check` and `make test` will also work.
