[Discuss-gnuradio] Runtime issue with gr_modtool block

[Tommy Tracy II]

Dear List,

I recently moved a custom block to a new virtual machine, built and compiled, and tried to import. I get the following error:

>>> import router

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

  File "/home/tjt7a/Src/target/lib/python2.7/dist-packages/router/__init__.py", line 45, in <module>

    from router_swig import *

  File "/home/tjt7a/Src/target/lib/python2.7/dist-packages/router/router_swig.py", line 26, in <module>

    _router_swig = swig_import_helper()

  File "/home/tjt7a/Src/target/lib/python2.7/dist-packages/router/router_swig.py", line 22, in swig_import_helper

    _mod = imp.load_module('_router_swig', fp, pathname, description)

ImportError: /home/tjt7a/Src/target/lib/libgnuradio-router.so: undefined symbol: _ZN2gr12msg_accepter4postEN5boost13intrusive_ptrIN3pmt8pmt_baseEEES5_

Investigating this line, I get:

address@hidden:~/Src$ c++filt _ZN2gr12msg_accepter4postEN5boost13intrusive_ptrIN3pmt8pmt_baseEEES5_

gr::msg_accepter::post(boost::intrusive_ptr<pmt::pmt_base>, boost::intrusive_ptr<pmt::pmt_base>)

I'm running the new pybombs version:

address@hidden:~/Src$ gnuradio-config-info -v

3.7.2git-0-gd19aa281

Has anyone seen this?

Sincerely,
