Hi All,

I am trying to build OpenSim 4.0 from the source cose from a OSX, and I am following this instructions: https://github.com/opensim-org/opensim- ... sing-xcode

However I get the following error when I build the JAVA wrapping: Therefore when I run the test I get this output: MATLAB is installed on my Mac but in /Application. Do I need to run this code (https://github.com/opensim-org/opensim- ... tlab.cmake ) to fix the problem?

Many thanks.

Dario

What version of Matlab do you have? The issue is usually that your version is more recent than FindMatlab.cmake knows about.

You can probably install and the Matlab bindings will still work fine.

Dario,

Before you even look into Matlab, make sure the Java bindings build and that the java tests pass. Check for compilation errors of Java bindings, likely due to using wrong version of SWIG and/or JDK (Java 1.8 expected 9 unsupported).

@Chris: Thanks! Yep, I have installed Matlab 2019a.

@Ayman: Thanks! I think you're right. I got 8 errors and 4 warnings.

I have used Home-brew to install swing (currently version 4.0.1) and Java (version SE 13.0.2 ):
brew install cmake swig
brew cask install java

Does this look OK?

Thanks a lot.

Dario

Hi Dario,

Swig version 4.0 is not supported yet (we saw similar errors to what you got when we tried it out of the box), we're working on it but as of now please use SWIG 3.0.9 if you can and let us know if it solves your build issues.

Best regards,
-Ayman

Hi Ayman,

Thanks for the great tip.

I can confirm that SWIG 3.0.9 works well: I have downloaded SWIG 3.0.9 and followed this installation instructions:
1) Make sure you have installed pcre (Perl-Compatible Regular Expression) first to successfully compile SWIG.
2) Open a terminal window.
3) Make your working directory the folder: SWIG.
4) Type ./configure.
5) Type make.
6) Type sudo make install and input your administrator password upon prompt.
7) Make sure that the folder that contains the swig executable (the version to use is specified in Requirements to build the Integration yourself:) is in the Xcode PATH variable. The default location is /usr/local/bin.

Then I run again the following:

cd opensim_build
cmake ../opensim-core \
-DCMAKE_INSTALL_PREFIX="~/opensim_install" \
-DCMAKE_BUILD_TYPE=RelWithDebInfo \
-DBUILD_PYTHON_WRAPPING=ON \
-DBUILD_JAVA_WRAPPING=ON \
-DOPENSIM_DEPENDENCIES_DIR="~/opensim_dependencies_install" \
-DWITH_BTK=ON
make -j8
ctest -j8
make -j8 install

Hope it helps.

Dario
