Re: [Discuss-gnuradio] Issues moving gr-modtool blocks between OSs

You need to re-compile the source of the module in the gentoo computer because the libs and so many things is diferent in Gentoo vs Ubuntu
copy all project created by gr-modtool from ubuntu to gentoo and run in gentoo:

cd /path/your_blocks

rm build/ -rf

mkdir build

cd build

cmake ../

make

sudo make install

Dear Gnuradio Mailing List,

I created a gr-modtool block on my Ubuntu machine; it works well, but I want to run it on my Gentoo machine. At first, I thought I could just copy over the module in dist-packages, but that doesn't seem to work:

I copied my custom module from: /usr/local/lib/python2.7/dist-packages/tom

to (on my gentoo machine): /usr/lib/python2.7/site-packages/

I then tried an import and got the following error:

>>> import tom

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

  File "/usr/lib/python2.7/site-packages/tom/__init__.py", line 45, in <module>

    from tom_swig import *

  File "/usr/lib/python2.7/site-packages/tom/tom_swig.py", line 26, in <module>

    _tom_swig = swig_import_helper()

  File "/usr/lib/python2.7/site-packages/tom/tom_swig.py", line 22, in swig_import_helper

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

ImportError: /usr/lib/python2.7/site-packages/tom/_tom_swig.so: wrong ELF class: ELFCLASS64

This indicates that I need to rebuild my module. Is there a way to build a 32-bit version of the module on a 64 bit machine?
