[Qgis-developer] Fail to load Rmanage plugin

[Otto Dassau]

Hi,

ok, first problem was that libR.so is not found - thanks Joona for that
hint. Now I have probably the problem you described with incompatible version
of libgfortran. I guess, this the error you also got. Could you have a
look to find the details about that again, please?

Carson: apart from that the R-base package is build with the
--enable-R-shlib flag.

>>> from rpy2 import robjects
Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "/usr/share/qgis/python/qgis/utils.py", line 283, in _import
    mod = _builtin_import(name, globals, locals, fromlist, level)
  File "/usr/lib64/python2.7/site-packages/rpy2/robjects/__init__.py", line
14, in <module> import rpy2.rinterface as rinterface
  File "/usr/share/qgis/python/qgis/utils.py", line 283, in _import
    mod = _builtin_import(name, globals, locals, fromlist, level)
  File "/usr/lib64/python2.7/site-packages/rpy2/rinterface/__init__.py",
line 75, in <module> from rpy2.rinterface.rinterface import *
  File "/usr/share/qgis/python/qgis/utils.py", line 283, in _import
    mod = _builtin_import(name, globals, locals, fromlist, level)
ImportError: /usr/lib64/R/lib/libRlapack.so: undefined symbol:
_gfortran_concat_string

Regards
Otto
