CHAI is a derivative of MILK, much like CACAO, COFFEE, and Atmospheres. It's forked here to support adding modules written in C++ and to enable changes to the CMake build process.
Some of the libraries that CHAI depends on aren't available through vcpkg. Because of that, you'll need to install them with your system package manager. For Oracle Linux (and other RHEL derivatives), that looks like this:
dnf install -y python2 python3 python3-devel fftw3-devel zlib-devel net-snmp-devel readline-devel cmake libconfig glib2-devel c-ares-devel qt5-qtbase-devel qt5-qttools-devel qt5-qtmultimedia-devel libpcap libpcap-devel libxml2-devel perl libX11-devel libXft-devel libgcrypt-devel gperf libX11-devel libXft-devel libXext-devel libXext-devel libXrandr-devel libXi-devel libXcursor-devel libXdamage-devel libXinerama-devel libXxf86vm-devel mesa-libEGL-devel
The rest of the library dependencies are acquired with vcpkg.
First, setup:
git clone https://github.com/microsoft/vcpkg
cd vcpkg
./bootstrap-vcpkg.sh
Next, build.
./vcpkg install grpc cairo[fontconfig,freetype,gobject] opencv \
boost-accumulators boost-beast boost-interprocess boost-json \
boost-random boost-system boost-test boost-thread cfitsio \
cpp-httplib eigen3 flatbuffers gflags lodepng sqlite3 \
sqlitecpp yaml-cpp gsl hdf5[szip,threadsafe,tools,utils,zlib]
git clone --recurse-submodules -b dev git@github.com:asgardner/milk.git chai
git clone git@gitlab.com:mmtao/chai-config.git /etc/chai
In order to build chai, you will need to make sure your build environment is ready. If you're using Oracle Linux 8, these instructions are recommended.
./setup_chai_dev.sh
mkdir build-username
cd build-username
cmake -DCMAKE_BUILD_TYPE=Release ..
make
sudo make install
The indi service in mmtao-main expects to find the FPGA and housekeeper ethernet devices at enp216s0f0 and enp216s0f1.
Fortunately, you can rename ethernet devices in Linux. Assuming those interfaces are eno3 and eno4 on your server, here is how to do that.
ifconfig eno3 down
ip link set eno3 name enp216s0f0
mv /etc/sysconfig/network-scripts/ifcfg-eno3 /etc/sysconfig/network-scripts/ifcfg-enp216s0f0
sed -i -e 's/eno3/enp216s0f0/' /etc/sysconfig/network-scripts/ifcfg-enp216s0f0
ifconfig enp216s0f0 upand then the second interface:
ifconfig eno4 down
ip link set eno4 name enp216s0f1
mv /etc/sysconfig/network-scripts/ifcfg-eno4 /etc/sysconfig/network-scripts/ifcfg-enp216s0f1
sed -i -e 's/eno3/enp216s0f1/' /etc/sysconfig/network-scripts/ifcfg-enp216s0f1
ifconfig enp216s0f1 up
