Build CoreCLR on NetBSD

This guide will walk you through building CoreCLR on NetBSD. We'll start by showing how to set up your environment from scratch.

Environment

These instructions are written on NetBSD 7.x on the amd64 platform, since that's the release the team uses.

Older releases aren't supported because building CoreCLR requires the modern LLVM stack (Clang, libunwind, and LLDB) that is developed against the NetBSD-7.x branch.

Pull Requests are welcome to address other ports (like i386 or evbarm) as long as they don't break the ability to use NetBSD/amd64.

Minimum RAM required to build is 1GB.

The pkgsrc framework is required to build .NET projects on NetBSD. Minimal pkgsrc version required is 2016Q1.

pkgsrc setup

Fetch pkgsrc and install to the system. By default it's done in the /usr directory as root:

ftp -o- ftp://ftp.netbsd.org/pub/pkgsrc/stable/pkgsrc.tar.gz | tar -zxpf- -C /usr

The .NET projects are tracked in pkgsrc-wip.

In order to use pkgsrc-wip, git must be installed:

cd /usr/pkgsrc/devel/git-base && make install

To access resources over SSL link, mozilla-rootcerts must be installed:

cd /usr/pkgsrc/security/mozilla-rootcerts && make install

And follow the MESSAGE commands to finish the installation.

Installing pkgsrc-wip

Type the following command to fetch the pkgsrc-wip sources:

cd /usr/pkgsrc
git clone --depth 1 git://wip.pkgsrc.org/pkgsrc-wip.git wip

Then install the CoreCLR package you need:

cd /usr/pkgsrc/wip/coreclr-git
make install

CoreCLR is installed in /usr/pkg/CoreCLR subdirectory by default.

PAL tests

To run PAL tests on NetBSD, use the make test in the coreclr-git package from pkgsrc-wip:

cd /usr/pkgsrc/wip/coreclr-git
make test

Build CoreFX

The CoreFX package is located in pkgsrc-wip as corefx-git. In order to build it you need to perform the following command:

cd /usr/pkgsrc/wip/corefx-git
make

At the moment there is no install or test target in the pkgsrc framework.

CoreFX tests

The steps to run CoreFX managed code tests:

Build CoreCLR (with pkgsrc-wip/coreclr-git) on NetBSD x64, Debug and install the Product dir to /usr/pkg/CoreCLR:

cd /usr/pkgsrc/wip/coreclr-git && make install

Build CoreFX native x64 Debug and the work (build) dir is in /usr/pkgsrc/wip/corefx-git/work/corefx:

cd /usr/pkgsrc/wip/corefx-git && make

Build CoreCLR Debug x64 on Linux and copy mscorlib.dll from ./bin/Product/Linux.x64.Debug/mscorlib.dll to NetBSD machine under /usr/pkg/CoreCLR:

./build.sh mscorlib Debug

Build CoreFX Debug x64 on Linux and copy bin/ to NetBSD machine under /public/bin:

./build.sh /p:OSGroup=NetBSD /p:SkipTests=true

Run ./run-test.sh:

$ pwd
/usr/pkgsrc/wip/corefx-git/work/corefx
$ ./run-test.sh \
--coreclr-bins /usr/pkg/CoreCLR/ \
--mscorlib-bins /usr/pkg/CoreCLR/ \
--corefx-tests /public/bin/tests/NetBSD.AnyCPU.Debug/ \
--corefx-native-bins ./bin/NetBSD.x64.Debug/Native/
