# The following enables several GHC versions to be tested; often it's enough to test only against the last release in a major GHC version. Feel free to omit lines listings versions you don't need/want testing for.

 # Sometimes GHC uses too much RAM for the travis server, causing the install script to fail.
 # In this case, we can fix the problem by reinstalling without optimizations.

# Here starts the actual work to be performed for the package under test; any command which exits with a non-zero exit code causes the build to fail.
script:
 - if [ -f configure.ac ]; then autoreconf -i; fi
 - cabal configure -fO0 --enable-tests --enable-benchmarks -v2  # -v2 provides useful information for debugging
 - cabal build # this builds all libraries and executables (including tests/benchmarks)
 - cabal test
 - cabal check
 - cabal sdist   # tests that a source-distribution can be generated

# Check that the resulting source distribution can be built & installed.
# If there are no other `.tar.gz` files in `dist`, this can be even simpler:
# `cabal install --force-reinstalls dist/*-*.tar.gz`
