Hi, thank you very much for reporting this. Do you think you could integrate your experience into the readme.md
and file a pull request?
Hi, yes I'll try to do it tonight.
Great, let me know if you have any trouble and I can try to help you.
Hello Jorrit, I was just wondering whether there is a procedure to implement the fortran library for the dielectric constant of water. In fact, this property is not directly available in the refpropm.m function. Have a nice weekend,
Hm, I could have a look. How do you get the values out in, let's say, FORTRAN? If you know how to do it, feel free to add it to your pull request. Nice weekend to you too!
Fortran
So I managed quite easily to compile the fortran libraries on : Mac OS X 10.8.5.
The important features of my system are:
and I followed the installation instructions indicated on : https://github.com/jowr/librefprop.so everything worked fine until I called make fortest (in order to test the installation), the logs I got are :
make fortest %-----------------------------
gfortran -O3 -ffast-math -fPIC -g -o ./src/ex_mix.o -c ./src/ex_mix.for
gfortran -g -o ./bin/ex_mix_for ./src/ex_mix.o -lrefprop -lgfortran
_Undefined symbols for architecture x86_64: "start", referenced from: -u command line option ld: symbol(s) not found for architecture x86_64 collect2: error: ld returned 1 exit status make: [bin/ex_mixfor] Error 1 %-----------------------------To make it work, I had to change it to:
%-----------------------------
gfortran -O3 -ffast-math -fPIC -g -o ./src/ex_mix.o -c ./src/ex_mix.for
gfortran -g -o ./bin/ex_mix_for ./src/ex_mix.o -lrefprop -lgfortran -lcrt1.o
%----------------------------- Note: This can be done directly in the Makefile in the line 336.and then it compiled properly. I don't know exactly why, I found on the web it has to do with some static libraries which are not linked without this option, but I am not a specialist.... Afterward I could execute
./bin/ex_mix_for
without any problem.I hope this can help some users of Mac OS...
Matlab
Then, I wanted to get the Integration with Matlab For sake of completeness I have a 64 bit installation (MATLAB_R2011a). I performed the steps as indicated on: https://github.com/jowr/librefprop.so
Then the second step:
Open Matlab, and run:
"cd /Users/thierrymeier/Documents/MATLAB/PhD/refProp9.1/librefprop.so-master/matlab;"
"run('thunk.m');"
proceed by pressing ENTER._rm matlab/refpropm.m.org matlab/rpproto64.m.org
There I had a problem while running
thunk.m
, as I currently have two gcc compiler installed ( Apple LLVM version 5.1 and gcc4.8.1) but none of them correspond exactly to gcc-4.2. Thus I created a symlink:sudo ln -s /usr/bin/gcc /usr/bin/gcc4.2
and it worked (I know its a little bit brute force but as a first shot...).
sudo make matlab-install
and the matlab function and the libraries were successfully copied in /opt/refprop as expected.path(path, '/opt/refprop')
permits to have a system wide use of the refprop functions.test.m
the refpropm function is called and Matlab crashes.... The log I get:%----------------------------- _Process: MATLAB [2368] Path: /Applications/MATLABR2011a.app/Contents/MacOS/StartMATLAB Identifier: com.mathworks.matlab Version: MATLAB Release 2011a (2.1) Code Type: X86-64 (Native) Parent Process: launchd [127] User ID: 501

suggests a problem with the dylib library. To overcome it, I read the thread on w3.mathworks.com (here) where Nathan suggest to rename the DYLIB fil in the MATLAB application directory and create a symlink with the one located in
/usr/local/lib
:ln -s /usr/local/lib/libgfortran.3.dylib /Applications/MATLAB_R2011a.app/sys/os/maci64/libgfortran.3.dylib
and then everything works. I hope this can help some users of Mac OS... I am not sure whether it is the nicest solution to do it, but who cares?
Cheers,
