Build and install miallib

Get the source code from miallib, to create the library:

git clone https://github.com/ec-jrc/jeolib-miallib.git
cd jeolib-miallib
mkdir build
cd build
cmake ..

or without sudo rights, replace the last command with:

cmake -DCMAKE_INSTALL_PREFIX=/home/user/install/miallib ..

Build the miallib library:

cmake --build .

Install the miallib library (remove sudo to install without sudo rights):

sudo cmake --install .

Build and install jiplib

Get the source code from jiplib:

git clone https://github.com/ec-jrc/jeolib-jiplib.git
cd jeolib-jiplib
mkdir build
cd build
cmake ..

or without sudo rights, replace the last command with:

cmake -DCMAKE_PREFIX_PATH=/home/user/install/miallib -DCMAKE_INSTALL_PREFIX=/home/user/install/jiplib ..

Build the jiplib library and create a python wheel:

cmake --build .

Install the jiplib library:

cmake --install .

To only install the Python bindings using the wheel that has been built:

cmake --install . --component wheels

Test the installation

From the build directory, run:

ctest .

Build documentation (deprecated, users are encouraged to use pyjeo documentation)

Go to directory doc and run make html.

cd doc
make html
