Support for C, C++ and Go projects
Travis CI was designed to be an awesome testing service for anyone and everyone. With over 16,000 projects on Travis to date, it is not uncommon to see people pushing the boundaries and building projects Travis CI does not have native support for.
Over time we noticed that some languages gain enough traction on Travis that it makes sense to provide some sugar so that configuration and setup becomes as simple as counting to three. From fairly early on we've seen C and C++ projects being built and tested on Travis, as well as a surge of Go projects as of late.
Today we are happy to announce first class support for C, C++ and Go projects.
C and C++ support
To tell Travis CI to use the C builder for your project, specify the following:
and for C++ it is "cpp":
By default Travis CI will run
./configure && make && make test
to compile your project and run the tests. It is possible to override this behavior by specifying your own
Historically, Travis CI environment only had GCC (currently 4.6) preinstalled but with the first class support for C and C++ project, we've added Clang (3.1) and introduced a way to switch compilers using the
compiler key in
For example, to build with Clang you just need to add the following to your .travis.yml:
or both GCC and Clang:
compiler: - clang - gcc
Testing against two compilers will create two rows in your build matrix, or possibly more depending on your other configuration settings. If you are familiar with how testing against multiple Ruby versions or JDKs works on Travis this should sound familiar.
During each test the Travis CI C builder will export the
CXX env variable to point to either g++ or clang++ and
CC to either gcc or clang.
Some real world examples that already use C++ support and test against both GCC and Clang:
Although the Go community is young and practices around continuous integration for Go libraries and applications are still being discussed, we have had many people shout out for first class support in Travis.
Travis VMs are 32 bit and currently provide
- go 1.0
- core GNU build toolchain (autotools, make), cmake, scons
Go projects on Travis assume you use Make or the Go build tool by default. If there is a Makefile in your repository root Travis will just run
make, otherwise it will run
go get -d -v && go build -v
to build your project's dependencies and
go test -v
to run tests.
To tell Travis CI to pick the Go builder for your project, specify the following:
Here are some projects using it today:
Our documentation guides cover Go support on Travis CI. There is no support for multiple versions of Go because at the moment as the only released version of Go is 1.0.
