Failure to import tif_lzw #28

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. I am using the Canopy Python installation v 1.1.1.1452, which includes 
Enthought Canopy Python 2.7.3 | 64-bit [GCC 4.1.2 20080704 (Red Hat 4.1.2-52)] 
on linux2. I also installed tiff-4.0.3 from source. I set LD_LIBRARY_PATH to 
include the Enthought Python lib directory, and subsequently the libtiff 
directory in site-packages.
2. I downloaded pylibtiff using 'svn checkout 
http://pylibtiff.googlecode.com/svn/trunk/ pylibtiff-read-only' and ran python 
setup.py install. 
3. I ran nosetests libtiff/tests/ from the pylibtiff-read-only directory.

What is the expected output? What do you see instead?
I get the following output with an import error for tif_lzw.:

$ nosetests libtiff/tests/
EEEEE

Ran 5 tests in 0.449s

FAILED (errors=5)

If I succeed in suppressing the tif_lzw import error (by commenting out the 
imports), I get a segmentation fault.

I also experience this error with Continuum Anaconda distribution, on both OSX 
10.8.4 and Linux Mint 16.

tif_lzw is an extension module that is built during installation. The import 
error is raised because tests are run from source directory where Python picks 
up unbuilt packages.
As a fix, change to different directory (that has no libtiff subdirectory) and 
try using libtiff again.

If one does not want to install libtiff but just try it from source directory, 
then one should run inplace build first.
