Version Problem?

Hi all,

after a fresh build of gnuradio on a gentoo 64 bit system the qtgui
stuff doesn’t work anymore.

Make test fails with. The output is:

Start testing: Feb 07 17:11 CET

1/1 Testing: qa_qtgui
1/1 Test: qa_qtgui
Command: “/bin/sh”
“qa_qtgui” start time: Feb 07 17:11 CET

Traceback (most recent call last):

line 26, in
_qtgui_swig = swig_import_helper()
line 22, in swig_import_helper
_mod = imp.load_module(’_qtgui_swig’, fp, pathname, description)
undefined symbol:

Test time = 0.24 sec

Test Failed.
“qa_qtgui” end time: Feb 07 17:11 CET
“qa_qtgui” time elapsed: 00:00:00

qwt 6.0.2 and qt-4.8.4 are installed.

Any ideas ?

Thanks in advance

Hi Volker,

I’m guessing that you are using the master branch from the name of your
library? (not that that changes too much).

This strikes me as an issue with a library linking problem. I’d
deleting your CMakeCache.txt file in your build directory, rerun cmake,
then rebuild (might even want to ‘make clean’ in gr-qtgui). QwtScaleMap
definitely exists in Qwt 6.0.2, and I’m using it right now. I think
something just got confused in a version change somewhere.
