1 .. _cross_compile_macos :
3 Cross compilation on MacOS
4 ==========================
6 This is a first attempt to support Cross compilation of VPP on MacOS for development (linting, completion, compile_commands.json)
11 * You'll need to install the following packages
13 .. code-block:: console
15 $ pip3 install ply pyyaml jsonschema
16 $ brew install diffutils gnu-sed pkg-config ninja crosstool-ng
18 * You'll also need to install ``gnu-ident 2.2.11`` to be able to ``make checkstyle``. This can be done with :ref:`this doc<install_indent_2_2_11>`
19 * You should link the binaries to make them available in your path with their original names e.g. :
21 .. code-block:: console
23 $ ln -s $(which gsed) /usr/local/bin/sed
24 $ ln -s $(which gindent) /usr/local/bin/indent
25 $ ln -s /usr/local/Cellar/diffutils/3.7/bin/diff /usr/local/bin/diff
30 * Create a `cross compile toolchain <https://crosstool-ng.github.io/>`_
31 * Create a case sensitive volume and mount the toolchain in it e.g. in ``/Volumes/xchain``
32 * Create a xchain.toolchain file with ``$VPP_DIR/extras/scripts/cross_compile_macos.sh conf /Volumes/xchan``
34 For now we don't support e-build so dpdk, rdma, quicly won't be compiled as part of ``make build``
36 To build with the toolchain do:
38 .. code-block:: console
40 $ $VPP_DIR/extras/scripts/cross_compile_macos.sh build
43 To get the compile_commands.json do
45 .. code-block:: console
47 $ $VPP_DIR/extras/scripts/cross_compile_macos.sh cc
48 $ >> ./build-root/build-vpp[_debug]-native/vpp/compile_commands.json
52 This should build vpp on MacOS
57 .. _install_indent_2_2_11 :
59 Installing indent 2.2.11
60 ------------------------
62 In order to install indent on macos :
66 $ wget http://mirror.sergal.org/gnu/indent/indent-2.2.11.tar.gz
67 $ tar -xzvf indent-2.2.11.tar.gz
69 $ ./configure --disable-dependency-tracking --disable-debug --program-prefix=g --prefix=/usr/local/Cellar/gnu-indent/2.2.11
71 Install will exit with an error code, but indent 2.2.11 will still be installed in ``/usr/local/bin/gindent``
72 Other mirrors can be found on the `GNU website <https://www.gnu.org/prep/ftp.html>`_
