Install on Debian sid

[dfgood...@googlemail.com]

I have read the CGAL bindings installation instructions and I getting all manner of errors when I run cmake.

I suspect that the problem is step two, where it tells me to choose between in-source of out-of-source, 

but then does not tell me what to do having made the decision.

I have got the debian source package (currently 4.0.2) in /usr/src/cgal-4.0.2, and I have the bindings 

checked out in ~/git/cgal-bindings.

The example given at the bottom of the page does not seem to do anything with the result of the choice in

stage 2.

The errors I get are complaining about missing directories (under SWIG_CGAL), and then when I created

these manually it started to complain that each directory did not have a CMakeList.txt in it.  I guess this

is because I did not tell cmake where the source was, but I can not see a way to do it.

Thanks in advance.

It simply means if you run CMake inside or outside of the source-tree.

# in-source
$ cd /path/to/cgal/bindings
$ cmake . # clutter my source-dir with build files

# out-of-source (recommended)
$ cd /path/to/cgal/bindings
$ mkdir build && cd build
$ cmake .. # notice the two dots

The "build" directory could be anywhere but most people make it a
sub-directory of the source-tree.

The location of the CGAL package should be automatically detected. I
don't know if you actually need the src package, as most of the code is
in the headers anyway. The normal should be sufficient.

Thank you, that fixed it.

 

It might be worth updating the installation instructions to reflect this.

The way it it shown the cmake command should be:-

 

cmake ../.. -DCGAL_DIR=/usr/lib/CGAL -DBUILD_PYTHON=OFF -DJAVA_OUTDIR_PREFIX=../../examples/java ../..

 

(obviously all on one line).
