Cross compilation on MacOS¶
This is a first attempt to support Cross compilation of VPP on MacOS for development (linting, completion, compile_commands.json)
Prerequisites
You’ll need to install the following packages
pip3 install ply
brew install diffutils gnu-sed pkg-config ninja crosstool-ng
You’ll also need to install
gnu-ident 2.2.11
to be able tomake checkstyle
. You can get it from GNUYou should link the binaries to make them available in your path with their original names e.g. :
ln -s $(which gsed) /usr/local/bin/sed
ln -s $(which gindent) /usr/local/bin/indent
ln -s /usr/local/Cellar/diffutils/3.7/bin/diff /usr/local/bin/diff
Setup
Create a cross compile toolchain
Create a case sensitive volume and mount the toolchain in it e.g. in
/Volumes/xchain
Create a xchain.toolchain file with
$VPP_DIR/extras/scripts/cross_compile_macos.sh conf /Volumes/xchan
For now we don’t support e-build so dpdk, rdma, quicly won’t be compiled as part of make build
To build with the toolchain do:
$VPP_DIR/extras/scripts/cross_compile_macos.sh build
To get the compile_commands.json do
$VPP_DIR/extras/scripts/cross_compile_macos.sh cc
# >> ./build-root/build-vpp[_debug]-native/vpp/compile_commands.json
This should build vpp on MacOS
Good luck :)
