GDL on OSX

packages

GDL is available from:

• Homebrew: https://github.com/brewsci/homebrew-science/blob/master/Formula/gnudatalanguage.rb
• Macports: https://github.com/macports/macports-ports/tree/master/math/gnudatalanguage
• Fink: http://finkproject.org/pdb/package.php/gdl

compilation

We have various difficult points when compiling GDL from source :

• activating OpenMP. Depending of OSX version, default Clang may or not come with OpenMP. If OpenMP is not around, we need to deactivated it :

cmake . [others flags] -DOPENMP=OFF

• activating Readline. Editline is not fully compliant with Readline but it wrongly made symbolic links with readline headers files. Very dangerous. You must install a clean Readline lib. around (the one provided by Brew is OK) then cleanly link to it :

cmake . [others flags] -DREADLINEDIR=/usr/local/opt/readline/

An example working (tested) on OSX 10.11, 10.12 & 10.14 (with Readline provided by Brew, and Cmake >= 3.0) :

git clone https://github.com/gnudatalanguage/gdl
cd gdl
mkdir build
cd build
cmake .. -DREADLINEDIR=/usr/local/opt/readline/ -DOPENMP=OFF -DWXWIDGETS=OFF
-DGEOTIFF=OFF  -DHDF=OFF  -DUDUNITS2=OFF -DPSLIB=OFF -DGRIB=off -DGLPK=OFF
make -j 4
make check  (few tests will fail)
