Hi all!
I've run into problems with swig in a project generated by gr_modtool.
When I run
ctest -V -R tle_cc
the test fails with import error:
2: Traceback (most recent call last):
2: File "/home/ec/Thesis/blocks/gr-doppler/python/qa_doppler_tle_cc.py",
line 25, in <module>
2: import doppler_swig as doppler

line 28, in <module>
2: _doppler_swig = swig_import_helper()

2: _mod = imp.load_module('_doppler_swig', fp, pathname, description)

Objdump has this to say:
ec@GR:~/Thesis/blocks/gr-doppler/build$ objdump -tT
lib/libgnuradio-doppler.so | grep _ZTIN2gr7doppler14doppler_tle_ccE
0000000000000000 *UND* 0000000000000000
_ZTIN2gr7doppler14doppler_tle_ccE
0000000000000000 D *UND* 0000000000000000
_ZTIN2gr7doppler14doppler_tle_ccE
doppler_tle_cc.h is the public header, with doppler_tle_cc_impl.cc/.h being
the implementation header and source. The code compiles.
The test worked before. I refactored the parameters and added setters and
getters, and initialized some variables, but can't pinpoint which of these
broke it.
I know this is not a lot to go on, but perhaps someone has seen something
like this before and can chime in on where to look?
All the best
Laur Joost
