This post is to show how to compile Scilab with source in Ubuntu 16.04 from my experience. (Ignore what is not working in your environment.)


Scilab is using Git to manage the source code and the dependencies are managed on Subversion as per platform binary libraries. So make sure that you have installed git and subversion.

1 Get Sources of Scilab

Get the source code from Git:

git clone -b master --depth=1 git:// [SCI_GIT_DIR]

Or when you have an account in Scilab:

git clone -b master ssh://[USERNAME] [SCI_GIT_DIR]

Then get the libraries of dependencies from subversion:

svn --force checkout --username anonymous --password Scilab svn://[linux_x64 | linux]/ [SCI_GIT_DIR]/scilab/

2 Install some other Dependencies

Install gfortran, g++, ocaml-nox, libgl1-mesa-dev, libtool and automake (if there were some problems when running ‘./configure’):

sudo apt-get install gfortran
sudo apt-get install g++
sudo apt-get install ocaml-nox
sudo apt-get install libgl1-mesa-dev
sudo apt-get install libtool
sudo apt-get install automake

Install OracleJDK instead of OpenJDK. There are many ways to install JDK.

  1. Update apt repository to install:
sudo add-apt-repository ppa:webupd8team/java
sudo apt update
sudo apt install oracle-java8-installer
  1. Download the binaries from the official website and configure it.
sudo update-alternatives --install /usr/bin/java java [JAVA_PATH] 200
sudo update-alternatives --install /usr/bin/javac javac [JAVAC_PATH] 200

3 Compile

In the source directory, compile it:

cd [SCI_GIT_DIR]/scilab
export LD_LIBRARY_PATH=`pwd`/lib/thirdparty/
LD_LIBRARY_PATH=`pwd`/lib/thirdparty/ ./configure --prefix=[SCI_INSTALL_DIR]
make install

4 After Installation

If these files,, are missing, try to find them in JRE directory or the thirdpart JRE directory:

ln -s /usr/workspace/git/scilab_git/scilab/java/jre1.8.0_51/lib/amd64/
ln -s /usr/workspace/git/scilab_git/scilab/java/jre1.8.0_51/lib/amd64/
ln -s /usr/workspace/git/scilab_git/scilab/java/jre1.8.0_51/lib/amd64/server/

You could aslo try to copy the thirdpart libraries to the scilab directory if you don’t want to set the LD_LIBRARY_PATH env variable.

cp -r [SCI_GIT_DIR]/scilab/thirdparty/ [SCI_INSTALL_DIR]/
cp -r [SCI_GIT_DIR]/scilab/lib/thirdparty/ [SCI_INSTALL_DIR]/lib/

And you might also need to modify the librarypath.xml file in [SCI_INSTALL_DIR]/share/scilab/etc.

<path value="$SCILAB/../../bin"/>
<path value="$SCILAB/../../lib/scilab/"/>
<path value="$SCILAB/../../lib/thirdparty/"/>

5 Run

In the scilab install directory [SCI_INSTALL_DIR]:



  1. Compilation of Scilab
  2. Compiling Scilab 5.x under GNU-Linux Unix
  3. Dependencies of Scilab 5.X
