Unable to custom Grass modules

[Audrey L]

Hi Joel - Hope all is going well.

I am trying to install MDiG on the computer of the uni and have a quick help request:

- After installing numpy and scipy separtely as per the instructions at https://github.com/ferrouswheel/mdig

mkvirtualenv mdig
pip install numpy
pip install scipy

the graphic interface of Grass does not work anymore.
> Error wxGui reguires wxpython.
I could manage to reinstall all packages required to run Grass but wanted to notify the issue

When I want to custom Grass modules as per the instructions at https://github.com/ferrouswheel/mdig

cd grass-modules
sudo make MODULE_TOPDIR=/usr/lib/grass64
Makefile:17: /usr/lib/grass64/include/Make/Dir.make: No such file or directory
make: *** No rule to make target `/usr/lib/grass64/include/Make/Dir.make'.  Stop.

The file include does not exists.
I tried to install grass from the source and to run

cd mdig/grass-modules
export GRASS_SRC=~/src/grass64_release
make -S MODULE_TOPDIR=$GRASS_SRC
Makefile:17: /home/audrey/src/grass64_release/include/Make/Dir.make: No such file or directory
make: *** No rule to make target `/home/audrey/src/grass64_release/include/Make/Dir.make'.  Stop.

Am I doing something wrong?
Thanks for your help

Best,
Audrey

Unfortunately using a virtualenv hides all the python libraries that
the GRASS user interface uses. I probably didn't notice this because I
tend to work on the command line.

Is there a directory called "/usr/lib/grass64"? It will only be called
this if you installed the Ubuntu version of GRASS.

If you installed from source code originally, then the correct
directory to use might be /usr/local/grass-6.4.3svn/

Check if the grass64_release/include/Make directory exists.

If you the "make" files don't exist, then it might because
"./configure" hasn't been run. ./configure will check that your
computer has all the correct dependencies before generating the make
files needed for the grass-modules to be built.

Hope that helps!

Thanks Joel - It was very helpful.
I did not realized that I was installing grass-6.5.svn so the file grass64 could not exist!

I have another help request
I have installed and compiled everything as per the instructions at https://github.com/ferrouswheel/mdig without error
but while trying to run Mdig I have the following error

audrey@ubuntu:~/mdig/mdig$ python mdig.py --help
Traceback (most recent call last):
  File "mdig.py", line 32, in <module>
    from mdig import actions
  File "/home/audrey/mdig/mdig/mdig/actions/__init__.py", line 5, in <module>
    from .admin import AdminAction, ListAction, AddAction, ResetAction, RemoveAction, RepositoryAction, InfoAction

  File "/home/audrey/mdig/mdig/mdig/model.py", line 31, in <module>
    import lxml.etree

Any suggestions where the problem comes from?
Best,
Audrey

The issue was fixed. Instructions to install

python-lxml

does not appear at https://github.com/ferrouswheel/mdig

MDiG is running now :)
Thanks a lot for your help.
