[GIS] Error installing GDAL 1.9.0 python package

gdallinuxpython

I'm trying to install the GDAL python package in a python 2.7.1 environment on RHEL 5. I am using the command 'pip install GDAL'. I have no problem installing other packages like numpy, etc. in this manner.

The installation fails with this error:

extensions/gdal_wrap.cpp: In function 'PyObject* _wrap_VSIFTruncateL(PyObject*, PyObject*)':

extensions/gdal_wrap.cpp:6845: error: 'VSIFTruncateL' was not declared in this scope

error: command 'gcc' failed with exit status 1

I also tried compiling GDAL 1.9.0 from source and running 'python setup.py build' (after setting the path to gdal-config in setup.cfg) and 'python setup.py install'. The GDAL python bindings seem to install okay, but I get the same 'VSIFTruncateL' error when trying to use GDAL…

>>> from osgeo import gdal
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "osgeo/__init__.py", line 21, in <module>
    _gdal = swig_import_helper()
  File "osgeo/__init__.py", line 17, in swig_import_helper
    _mod = imp.load_module('_gdal', fp, pathname, description)
ImportError: osgeo/_gdal.so: undefined symbol: VSIFTruncateL

Does the version of the GDAL python package you are trying to install match the one for your GDAL installation?

I was having the same problem because I was trying to build the GDAL python package v1.9.0 against GDAL v1.8.1 that I had previously installed on my development machine.

Simply telling pip to use v1.8.1 solved this issue for me.

pip install GDAL==1.8.1

NOTE: I'm using a Mac but was seeing the exact same error as you.
