Building
Build CoreCLR on Unix.
Building the Tests
DotNet is required to build the tests, this can be done on any platform then copied over if the arch or os does not support DotNet. If DotNet is not supported, CoreFX is also required to be built.
To build the tests on Unix:
./build-test.sh
To build on Windows:
C:\coreclr>build-test.cmd
Please note that this builds the Priority 0 tests. To build priority 1:
build-test.sh -priority 1
Building Individual Tests
During development there are many instances where building an individual test is fast and necessary. All of the necessary tools to build are under coreclr/Tools. It is possible to use coreclr/Tools/MSBuild.dll as you would normally use MSBuild with a few caveats.
Note that coreclr/Tools/msbuild.sh exists as well to make the call shorter.
!! Note !! -- Passing /p:__BuildOs=[OSX|Linux] is required.
If you omit it you will get the following error:
error MSB4801: The task factory "CodeTaskFactory" could not be loaded because this version of MSBuild does not support it.
Building an Individual Test Example
coreclr/Tools/msbuild.sh /maxcpucount coreclr/tests/src/JIT/CodeGenBringUpTests/Array1.csproj /p:__BuildType=Release /p:__BuildOS=OSX
Or
coreclr/Tools/dotnetcli/dotnet coreclr/Tools/MSBuild.dll /maxcpucount coreclr/tests/src/JIT/CodeGenBringUpTests/Array1.csproj /p:__BuildType=Release /p:__BuildOS=OSX
Aarch64/armhf multiarch
For machines that have aarch64/armhf support, all the armhf packages will need to also be downloaded. Please note you will need to enable multiplatform support as well. Check with your distro provider or kernel options to see if this is supported. For simplicity, these instructions relate to aarch64 ubuntu enabling arm32 (hf) coreclr runs.
Please make sure your device is running a 64 bit aarch64 kernel.
# Example output
[ubuntu:~]: uname -a
Linux tegra-ubuntu 4.4.38-tegra #1 SMP PREEMPT Thu Jul 20 00:41:06 PDT 2017 aarch64 aarch64 aarch64 GNU/Linux
# Enable armhf multiplatform support
[ubuntu:~]: sudo dpkg --add-architecture armhf
[ubuntu:~]: sudo apt-get update
[ubuntu:~]: sudo apt-get install libstdc++6:armhf
At this point you should be able to run a 32bit corerun. You can verify this by downloading and running a recently built arm32 coreclr.
[ubuntu:~]: wget https://ci.dot.net/job/dotnet_coreclr/job/master/job/armlb_cross_checked_ubuntu/lastSuccessfulBuild/artifact/*zip*/archive.zip --no-check-certificate
[ubuntu:~]: unzip archive.zip
[ubuntu:~]: chmod +x && ./archive/bin/Product/Linux.arm.Checked/corerun
Execute the specified managed assembly with the passed in arguments
Options:
-c, --clr-path path to the libcoreclr.so and the managed CLR assemblies
Now download the coreclr armhf dependencies.
sudo apt-get install libunwind8:armhf libunwind8-dev:armhf libicu-dev:armhf liblttng-ust-dev:armhf libcurl4-openssl-dev:armhf libicu-dev:armhf libssl-dev libkrb5-dev:armhf
Running tests
The following instructions assume that on the Unix machine:
- The CoreCLR repo is cloned at
/mnt/coreclr
If DotNet is unsupported
- The CoreFX repo is cloned at
/mnt/corefx
- The other platform's clone of the CoreCLR repo is mounted at
/media/coreclr
The following steps are different if DotNet is supported or not on your arch and os.
DotNet is supported
build-test.sh will have setup the Core_Root directory correctly after the test build. If this was either skipped or needs to be regenerated use:
build-test.sh generatelayoutonly
To run the tests run with the --coreOverlayDir path
~/coreclr$ tests/runtest.sh --testRootDir=/mnt/coreclr/bin/tests/Linux.x64.Debug --testNativeBinDir=/mnt/coreclr/bin/obj/Linux.x64.Debug/tests --coreOverlayDir=/mnt/coreclr/bin/tests/Linux.x64.Debug/Tests/Core_Root --copyNativeTestBin
DotNet is not supported
Tests need to be built on another platform and copied over to the Unix machine for testing. Copy the test build over to the Unix machine:
cp --recursive /media/coreclr/bin/tests/Windows_NT.x64.Debug /mnt/test/
See runtest.sh usage information:
/mnt/coreclr$ tests/runtest.sh --help
Run tests (Debug
may be replaced with Release
or Checked
, depending on which Configuration you've built):
/mnt/coreclr$ tests/runtest.sh --testRootDir=/mnt/test/Windows_NT.x64.Debug --testNativeBinDir=/mnt/coreclr/bin/obj/Linux.x64.Debug/tests --coreClrBinDir=/mnt/coreclr/bin/Product/Linux.x64.Debug --mscorlibDir=/mnt/coreclr/bin/Product/Linux.x64.Debug --coreFxBinDir=/mnt/corefx/bin/runtime/netcoreapp-Linux-Debug-x64
The method above will copy dependencies from the set of directories provided to create an 'overlay' directory.
Results
Test results will go into:
~/test/Windows_NT.x64.Debug/coreclrtests.xml
Unsupported and temporarily disabled tests
These tests are skipped by default:
- Tests that are not supported outside Windows, are listed in:
~/coreclr/tests/testsUnsupportedOutsideWindows.txt
- Tests that are temporarily disabled outside Windows due to unexpected failures (pending investigation), are listed in:
~/coreclr/tests/testsFailingOutsideWindows.txt
To run only the set of temporarily disabled tests, pass in the --runFailingTestsOnly
argument to runtest.sh
.
Build CoreCLR on the Unix machine.
Run tests:
~/coreclr$ src/pal/tests/palsuite/runpaltests.sh ~/coreclr/bin/obj/Linux.x64.Debug
Test results will go into:
/tmp/PalTestOutput/default/pal_tests.xml
