This GitHub is part of:

The goal of this project is to have a clean Travis CI build, with specs:

Build system: qmake
C++ compiler: gcc
C++ version: C++14
Libraries: STL only
Code coverage: none
Source: one single file, main.cpp

More complex builds:

Use C++17: travis_qmake_gcc_cpp17
Use C++20: travis_qmake_gcc_cpp20
Add Bio++: travis_qmake_gcc_cpp14_bpp
Add Boost: travis_qmake_gcc_cpp14_boost
Add Boost.Graph: travis_qmake_gcc_cpp14_boost_graph
Add Boost.Test: travis_qmake_gcc_cpp14_boost_test
Use Boost on XML: travis_qmake_gcc_cpp14_boost_xml
Add clang-tidy: travis_qmake_gcc_cpp14_clang-tidy
Add CodeChecker: travis_qmake_gcc_cpp14_codechecker
Add Doxygen: travis_qmake_gcc_cpp14_doxygen
Add code coverage: travis_qmake_gcc_cpp14_gcov
Add cppcheck: travis_qmake_gcc_cpp14_cppcheck
Add FLTK: travis_qmake_gcc_cpp14_fltk
Add gprof: travis_qmake_gcc_cpp14_gprof
Add OCLint: travis_qmake_gcc_cpp14_oclint
Add perf: travis_qmake_gcc_cpp14_perf
Add Qt: travis_qmake_gcc_cpp14_qt
Add R: travis_qmake_gcc_cpp14_r
Add SDL: travis_qmake_gcc_cpp14_sdl
Add SFML: travis_qmake_gcc_cpp14_sfml
Add Rcpp: travis_qmake_gcc_cpp14_rcpp
Add Urho3D: travis_qmake_gcc_cpp14_urho3d
Add Wt: travis_qmake_gcc_cpp14_wt
Add xml++: travis_qmake_gcc_cpp14_xmlpp
Travis-dependent compilation: travis_qmake_gcc_cpp14_tdc
Travis-dependent run: travis_qmake_gcc_cpp14_tdr

Builds of similar complexity:

Use clang instead of gcc: travis_qmake_clang_cpp14
Use cmake instead of qmake: travis_cmake_gcc_cpp14

Less complex builds:

Use C++98: travis_qmake_gcc_cpp98
Use C++11: travis_qmake_gcc_cpp11
