Collection of CMake toolchain files and scripts.

Every toolchain defines compiler/flags and two variables:
POLLY_TOOLCHAIN_NAMEPOLLY_TOOLCHAIN_TAG
First variable will be printed while processing file:
-- [polly] Used toolchain: Name of toolchain A
-- The CXX compiler identification is Clang 5.0.0
-- Check for working CXX compiler: /usr/bin/c++
-- [polly] Used toolchain: Name of toolchain A
-- Check for working CXX compiler: /usr/bin/c++ -- works
-- Detecting CXX compiler ABI info
-- [polly] Used toolchain: Name of toolchain A
-- Detecting CXX compiler ABI info - done
-- [polly] Used toolchain: Name of toolchain A
-- Configuring done
-- Generating done
-- Build files have been written to: ...
Second
variable coincide with toolchain file name and can be used to define CMAKE_INSTALL_PREFIX like:
set(CMAKE_INSTALL_PREFIX "${PROJECT_SOURCE_DIR}/_install/${POLLY_TOOLCHAIN_TAG}")In this case targets can coexist simultaneously:
- Project\ -
- CMakeLists.txt
- sources\
- documentation\
- ...
- _install\ -
- toolchain-A\
- toolchain-B\
- toolchain-C\
- ...
Note: This is a core idea of the tagged builds in hunter package manager.
Just define CMAKE_TOOLCHAIN_FILE variable:
> cmake -H. -B_builds/clang-libstdcxx -DCMAKE_TOOLCHAIN_FILE=${POLLY_ROOT}/clang-libstdcxx.cmake -DCMAKE_VERBOSE_MAKEFILE=ON
-- [polly] Used toolchain: clang / GNU Standard C++ Library (libstdc++) / c++11 support
-- The CXX compiler identification is Clang 5.0.0
-- Check for working CXX compiler: /usr/bin/c++
-- [polly] Used toolchain: clang / GNU Standard C++ Library (libstdc++) / c++11 support
-- Check for working CXX compiler: /usr/bin/c++ -- works
-- Detecting CXX compiler ABI info
-- [polly] Used toolchain: clang / GNU Standard C++ Library (libstdc++) / c++11 support
-- Detecting CXX compiler ABI info - done
-- Configuring done
-- Generating done
-- Build files have been written to: /.../_builds/make-debugTake a look at make output, you must see -stdlib=libstdc++ string:
> cmake --build _builds/clang_libstdcxx
/usr/bin/c++ -std=c++11 -stdlib=libstdc++ -o CMakeFiles/.../main.cpp.o -c /.../main.cpp
This is a python script that wrap cmake for you and automatically set:
- build directory for your toolchain. E.g.
_builds/xcode,_builds/libcxx-Debug,_builds/nmake-Release - local install directory. E.g.
_install/vs-12-2013-x64,_install/libcxx - start an IDE project (Xcode, Visual Studio) if option
--openpassed - run
ctestafter the build done if option--testpassed - run
cpackafter the build done if option--packpassed - create
OS X/iOSframework if option--frameworkpassed (can be used for broken iOS framework creation on CMake)
Example of usage (also see polly.py --help):
- build Debug Xcode project:
polly.py --toolchain xcode --config Debug(_builds/xcode)
- build and test Release Makefile project with
libcxx:polly.py --toolchain libcxx --config Release --test(_builds/libcxx-Release)
- install Debug Xcode project:
polly.py --toolchain xcode --config Debug --install(_builds/xcode,_install/xcode)
See examples. Please read coding style and agreements before start looking through examples (may explain a lot). Take a look at the Travis config files: mac and linux, it's quite self-explanatory.
