[Gmsh] gmsh 2.12.0 : gmshpy : installation directory

[Fabien Rozar]

Unfortunately, after these commands : 
$ cd /usr/local/gmshpy 
$ sudo python setup.py install 

I got a compilation error as follows: 
running install 
running build 
running build_py 
running build_ext 
building 'gmshpy._gmshCommon' extension 
x86_64-linux-gnu-gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -fPIC -DSWIG=1 -I./extra_include/ -I../include/gmsh/ -I/usr/include/python2.7 -c src/gmshCommonPYTHON_wrap.cxx -o build/temp.linux-x86_64-2.7/src/gmshCommonPYTHON_wrap.o

#include "GmshConfig.h" 
^ 
compilation terminated. 
error: command 'x86_64-linux-gnu-gcc' failed with exit status 1 

Do you know what's wrong ?

>> Hello,

>> I am a postdoc at LMGC in Montpellier with Frédéric Dubois as advisor. For
>> some user case of our software, LMGC90, we use the python module 'gmshpy'.

>> In order to use it on a new computer, I need to install it. I downloaded the
>> source of gmsh 2.12.0 from the web page :
>> http://gmsh.info/

>> Before the compilation, I configured the generation of 'gmshpy' with :
>> $ cd build
>> $ cmake -DENABLE_WRAP_PYTHON=ON .../gmsh-2.12.0-source
>> $ make

>> The module 'gmshpy' is well build under 'build/wrappers/gmshpy'.

>> The point is that, after the installation step :
>> $ sudo make install

>> the directory 'build/wrappers/gmshpy' is copied in '/usr/local' whereas
>> this directory is not part of python default search directories :
>> $ python -c "import sys; print '\n'.join(sys.path)"
>> /usr/lib/python2.7
>> /usr/lib/python2.7/plat-x86_64-linux-gnu
>> /usr/lib/python2.7/lib-tk
>> /usr/lib/python2.7/lib-old
>> /usr/lib/python2.7/lib-dynload
>> /usr/local/lib/python2.7/dist-packages
>> /usr/lib/python2.7/dist-packages
>> /usr/lib/pymodules/python2.7

> Hello. That might be a good idea (I dont' know how "make install" works in
> Gmsh), but in the meantime a workaround is:

> $ cd /usr/local/gmshpy
> $ sudo python setup.py install
> $ ldconfig

> That puts gmshpy in /usr/local/lib/python2.7/dist-packages, as requested.
