How-to compile OpenViBE 3.2.0 on Linux Ubuntu 20.04.

HOWTO_openvibe-3.2.0_compile-ubuntu-20.04.md

Instructions to compile OpenViBE 3.2.0 beta on Ubuntu 20.04

Get the sources: wget http://openvibe.inria.fr/pub/src/openvibe-3.2.0-src.tar.xz

Uncompress: tar xvf openvibe-3.2.0-src.tar.xz

Apply patch: patch -p0 < openvibe-3.2.0_compile-ubuntu-20.04.patch

Then proceed with usual install steps:

Go to openvibe-3.2.0-src and run linux-install_dependencies.sh and then buil.sh.

The resuling files will be stored in dist subfolder. Go to openvibe-3.2.0-src/dist/Release/, and run as usual openvibe-acquisition-server.sh and openvibe-designer.sh, enjoy!

symbol lookup errors

Upon running the designer and the acquisition server I had issues because the launching scripts were locating an old Matlab installation, which outdated libraries where placed first in LD_LIBRARY_PATH, creating issues such as symbol lookup error: /usr/lib/x86_64-linux-gnu/libpython3.8.so.1.0: undefined symbol: XML_SetHashSalt (caused by an old libexpat lib) or symbol lookup error: /usr/lib/x86_64-linux-gnu/libcairo.so.2: undefined symbol: FT_Get_Var_Design_Coordinates (caused by an old freetype lib, happy bug hunt). My stupid simple fix is to comment out the faulty parts in both dist/Release/openvibe-acquisition-server.sh and dist/Release/openvibe-designer.sh (I've never bridged OpenViBE with Matlab anyways), i.e.:

#if [ "`which matlab`" != "" ] ; then
#        MATLAB_ROOT=`matlab -e | grep "^MATLAB=" | sed -e "s/^MATLAB=//"`
#        MATLAB_ARCH=`matlab -e | grep "^ARCH=" | sed -e "s/^ARCH=//"`
#        MATLAB_LIBPATH="$MATLAB_ROOT/bin/$MATLAB_ARCH"
#        # echo Matlab libs expected at $MATLAB_LIBPATH
#        export LD_LIBRARY_PATH="$MATLAB_LIBPATH:$LD_LIBRARY_PATH"
#fi

A patch won't cut it and you have to get your hands dirty because those script posses hard-coded paths (hence avoid moving around the source folder once compiled).

As Earthfile for anyone interested. Shouldn't be hard to decompose Earthfile back to Dockerfile if this is preferred over Earthly.
