Problem to import memsurfer

[jfloresc]

Hi All,

I have successfully compiled memsurfer, after building locally GMP and MPFR libraries in the $MEM_HOME/external folder.

I try to import but I get the following error:

Python 3.7.0 (default, Jul 3 2018, 12:46:05)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.

import memsurfer
Traceback (most recent call last):
File "/mnt/software/python3.7/lib/python3.7/site-packages/memsurfer-1.0.0-py3.7-linux-x86_64.egg/memsurfer/pymemsurfer.py", line 18, in swig_import_helper
fp, pathname, description = imp.find_module('_pymemsurfer', [dirname(file)])
File "/mnt/software/python3.7/lib/python3.7/imp.py", line 297, in find_module
raise ImportError(_ERR_MSG.format(name), name=name)
ImportError: No module named '_pymemsurfer'

During handling of the above exception, another exception occurred:

ImportError: /mnt/software/python3.7/lib/python3.7/site-packages/memsurfer-1.0.0-py3.7-linux-x86_64.egg/_pymemsurfer.cpython-37m-x86_64-linux-gnu.so: undefined symbol: __gmpq_add

I would like to use local versions of GMP and MPFR since I am compiling for our local modules server.

Best regards,
Jose

I solved the problem by adding the following below LIBS_EXT.append('CGAL') in the setup.py file:

LIBS_EXT.append('gmp')
