A very specific successful install (coolprop v4 + EM master + dymola) about externalmedia

Thanks for sharing the input - I hope v3.3.0 makes this guide obsolete.

The one thing that was missing for me to get this to work was I had to update my gcc from the default 5 to 7 (the default for Ubuntu 18) as I was using Ubuntu 16. The steps to do this are below:

1. Get and install the gcc version

   sudo add-apt-repository ppa:ubuntu-toolchain-r/test
   sudo apt-get update
   sudo apt-get install gcc-7 g++-7
   gcc-7 --version
   

2. Add to the version controller to easily switch between versions

   sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-5 60 --slave /usr/bin/g++ g++ /usr/bin/g++-5 
   sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 --slave /usr/bin/g++ g++ /usr/bin/g++-7 
   sudo update-alternatives --config gcc
   

3. Now select the gcc version you desire and run make -f makefile-linux

I would suggest updating the makefiles to use the CC environment variable so you can switch using make CC=gcc-7 instead of playing with update-alternatives

Any updates for compiling for OSX (High Sierra) for OpenModelica?

[veeshy]

Sorry, I haven't tried for OSX, and I jumped to 10.14 where open Modelica won't install via macport right now :(. Nightly prebuilt works, though I haven't tried EM on it.

I think the combination of the correct coolprop listed above and building is your best bet though.

Thanks for the quick response! For a novice, is there a cheat sheet that can be useful specifically for OSX build? Looks like the make command covers linux.
thanks.

You install macports to get gmake and then make OpenModelica in the same way as on Linux. As long as you don't have the new XCode versions (Apple breaks building the binaries in every single release so we have an OSX 10.9 machine creating binaries which still run on newer OSX versions...)
