How to setup casa-dev environment for virtualbox

[nsouedet]

Actually, casa-dev environment for virtual box does not contain a ready to use environment, but it contains all the necessary dependencies and scripts to be able to build BrainVISA softwares and develop in CASA environment.
This discussion propose to complete the setup of the environment :

1°) Download the latest casa-dev for VitualBox ova image

2°) Follow instructions described in chapter "Install with VirtualBox" of https://brainvisa.info/web/download.html using casa-dev-5.0-2.ova file instead of a run image and start virtual machine casa-dev-5.0

3°) Create dirs in /casa/hosts :

cd /casa/host
mkdir bin build conf home install src

4°) Create casa-dev environment configuration script :

sudo bash -c "cat > /etc/profile.d/casa-dev.sh" <<EOF
#!/bin/sh
export CASA_SYSTEM='ubuntu-18.04'
export CASA_TYPE='dev'

# Use the software-only mesa library install in /usr/local/lib as a fallback
# (singularity puts the path to nvidia libraries in LD_LIBRARY_PATH).
LD_LIBRARY_PATH=\${LD_LIBRARY_PATH}\${LD_LIBRARY_PATH+:}/usr/local/lib
if [ "\$SOFTWARE_OPENGL" = "1" ]; then
    LD_LIBRARY_PATH=/usr/local/lib/mesa\${LD_LIBRARY_PATH+:}\${LD_LIBRARY_PATH}
fi
export LD_LIBRARY_PATH

# Source the environment that is defined in the casa-run and casa-dev images,
# if they exist.
if [ -f /casa/environment.sh ]; then
    . /casa/environment.sh
fi
if [ -f /casa/dev-environment.sh ]; then
    . /casa/dev-environment.sh
fi

# Allow user customizations like in a login shell - singularity runs the
# entrypoint shell as a non-interactive, non-login shell, thus reads no user
# init script; however the host config is not valid here thus is not inherited
# like in a non-login shell. In summary the situation here is similar to a
# login shell.
# Hence we source the user .profile file if it exists.

if [ -f "\$HOME/.profile" ]; then
    . "\$HOME/.profile"
fi

EOF

5°) Update the ~/.profile script to add the dev branch you want to use

cat > ~/.profile <<EOF
# the default umask is set in /etc/profile; for setting the umask
# for ssh logins, install and configure the libpam-umask package.
#umask 022

# if running bash
if [ -n "\$BASH_VERSION" ]; then
    # include .bashrc if it exists
    if [ -f "\$HOME/.bashrc" ]; then
        . "\$HOME/.bashrc"
    fi
fi

# set PATH so it includes user's private bin if it exists
if [ -d "\$HOME/bin" ] ; then
    export PATH="\$HOME/bin:\$PATH"
fi

# set PATH so it includes user's private bin if it exists
if [ -d "\$HOME/.local/bin" ] ; then
    export PATH="\$HOME/.local/bin:\$PATH"
fi

export CASA_BRANCH=master

EOF

6°) Create bv_maker configuration files
6.1) Create /casa/host/conf/bv_maker.cfg

cat  > /casa/host/conf/bv_maker.cfg" <<EOF
[ source \$CASA_SRC ]
  brainvisa brainvisa \$CASA_BRANCH

[ build \$CASA_BUILD ]
  default_steps = configure build doc
  make_options = -j\$NCPU
  #cmake_options = -DAIMS_DEBUG_IO=1 -DCARTO_DEBUGMODE=debug
  build_type = Release
  packaging_thirdparty = OFF
  clean_config = ON
  clean_build = ON
  test_ref_data_dir = \$CASA_TESTS/ref
  test_run_data_dir = \$CASA_TESTS/test
  brainvisa brainvisa \$CASA_BRANCH \$CASA_SRC
EOF

6.2) Create /casa/host/conf/svn.secret replacing and with bioproj login and password

cat  > /casa/host/conf/svn.secret" <<EOF
# This is a shell script that must set the variables SVN_USERNAME
# and SVN_PASSWORD. Do not forget to properly quote the variable
# especially if values contains special characters.

SVN_USERNAME='<user>'
SVN_PASSWORD='<password>'
EOF
