Common build target =
Build everything
make -f posix.mak -j4
Build with debug symbols
make -f posix.mak -j4 BUILD=debug
make -f posix.mak dll -j4
Build only as a static library
make -f posix.mak lib -j4
Testing
This section explains commonly commands which are commonly used to test the low level runtime library for the D programming language.
Run all tests
The entire druntime testsuite can be run with the unittest target:
make -f posix.mak unittest -j4
Run an individual test
Sometimes it can be helpful to rerun only a single test which tests the module or feature one is working on. For example:
make -f posix.mak test/coverage/.run
There are also unittest which have a different behavior when built in debug. To test this, you can set the BUILD mode:
make -f posix.mak test/exceptions/.run BUILD=debug
When you execute the unittest target, unittest-debug and unittest-release are tested.
Benchmarking
If you are making a bigger change or want to improve the performance of a specific function in druntime, you should run the included benchmark script:
rdmd benchmark/runbench.d
