Hello GR, I just installed GR 3.7 on my Centos 6.5 machine, everything I done is ok (I set the env. var. after accordingly). But when I run gnuradio-companion I got a bunch of errors appearing in the terminal: _Error: ‘DrawingArea’ object has no attribute ‘set\_can\_focus’_ > > > Failure > > > Traceback (most recent call last): > > > File > > > “~/gnuradio-3.7\_install/lib64/python2.6/site-packages/gnuradio/grc/gui/MainWindow.py”, > > > line 188, in new\_page > > > file\_path=file\_path, > > > File > > > “~/gnuradio-3.7\_install/lib64/python2.6/site-packages/gnuradio/grc/gui/NotebookPage.py”, > > > line 82, in **init** > > > self.drawing\_area = DrawingArea(self.get\_flow\_graph()) > > > File > > > “~/gnuradio-3.7\_install/lib64/python2.6/site-packages/gnuradio/grc/gui/DrawingArea.py”, > > > line 66, in **init** > > > self.set\_can\_focus(True) > > > _AttributeError: ‘DrawingArea’ object has no attribute ‘set\_can\_focus’_ > > > Traceback (most recent call last): > > > File > > > “~/gnuradio-3.7\_install/lib64/python2.6/site-packages/gnuradio/grc/gui/ActionHandler.py”, > > > line 357, in \_handle\_action > > > self.main\_window.reports\_scrolled\_window.set\_visible(visible) > > > AttributeError: ‘gtk.ScrolledWindow’ object has no attribute > > > ‘set\_visible’ > > > Traceback (most recent call last): > > > File > > > “~/gnuradio-3.7\_install/lib64/python2.6/site-packages/gnuradio/grc/gui/ActionHandler.py”, > > > line 361, in \_handle\_action > > > self.main\_window.btwin.set\_visible(visible) > > > AttributeError: ‘BlockTreeWindow’ object has no attribute ‘set\_visible’ > > > Traceback (most recent call last): > > > File > > > “~/gnuradio-3.7\_install/lib64/python2.6/site-packages/gnuradio/grc/gui/ActionHandler.py”, > > > line 489, in \_handle\_action > > > Actions.ERRORS\_WINDOW\_DISPLAY.set\_sensitive(not > > > self.get\_flow\_graph().is\_valid()) > > > File > > > “~/gnuradio-3.7\_install/lib64/python2.6/site-packages/gnuradio/grc/gui/MainWindow.py”, > > > line 304, in get\_flow\_graph > > > return self.get\_page().get\_flow\_graph() > > > \*AttributeError: ‘NoneType’ object has no attribute ‘get\_flow\_graph’ > > > \*^CTraceback (most recent call last): > > > File “~/gnuradio-3.7\_install/bin/gnuradio-companion”, line 72, in > > > > > > ActionHandler(args, Platform()) > > > File > > > “~/gnuradio-3.7\_install/lib64/python2.6/site-packages/gnuradio/grc/gui/ActionHandler.py”, > > > line 72, in **init** > > > gtk.main() And the window of grc appears but empty nothing inside just gray. BTW the menu bar appears but the blocks, output and the main windows does not. Trying to click close or click on any button of the menu bar give no result. One need to close the graph by Ctl+C in the terminal. Any hints or help is well appreciated.

Hi, looks like a version issue. Try updating to PyGTK 2.22 or above. Sebastian – Karlsruhe Institute of Technology (KIT) Communications Engineering Lab (CEL) Dipl.-Ing.

I opened an issue on [gnuradio.org](http://gnuradio.org) for this. [http://gnuradio.org/redmine/issues/653](http://gnuradio.org/redmine/issues/653) You can pull a fix from: [https://github.com/gnuradio/gnuradio-wg-grc/tree/grc\_pygtk\_backw\_compat\_fixes](https://github.com/gnuradio/gnuradio-wg-grc/tree/grc_pygtk_backw_compat_fixes) Let me know if that works for you.

Thank you Sebastian for your reply, I pulled your grc fixing, proceed to a clean make then did everything again however I got some error: [29%] Building CXX object gr-blocks/lib/CMakeFiles/gnuradio-blocks.dir/message\_strobe\_random\_impl.cc.o In file included from /raid/nae/gnuradio/gr-blocks/lib/message\_strobe\_random\_impl.cc:27: /raid/nae/gnuradio/gr-blocks/lib/message\_strobe\_random\_impl.h:48: error: ‘mt19937’ in namespace ‘boost::random’ does not name a type /raid/nae/gnuradio/gr-blocks/lib/message\_strobe\_random\_impl.cc: In constructor ‘gr::blocks::message\_strobe\_random\_impl::message\_strobe\_random\_impl(pmt::pmt\_t, gr::blocks::message\_strobe\_random\_distribution\_t, float, float)’: /raid/nae/gnuradio/gr-blocks/lib/message\_strobe\_random\_impl.cc:57: error: class ‘gr::blocks::message\_strobe\_random\_impl’ does not have any field named ‘d\_rng’ /raid/nae/gnuradio/gr-blocks/lib/message\_strobe\_random\_impl.cc: In member function ‘void gr::blocks::message\_strobe\_random\_impl::update\_dist()’: /raid/nae/gnuradio/gr-blocks/lib/message\_strobe\_random\_impl.cc:89: error: ‘d\_rng’ was not declared in this scope make[2]: \*\*\* [gr-blocks/lib/CMakeFiles/gnuradio-blocks.dir/message\_strobe\_random\_impl.cc.o] Error 1 make[1]: \*\*\* [gr-blocks/lib/CMakeFiles/gnuradio-blocks.dir/all] Error 2 The point is those errors I got them before so to fix them (at that time) I just went to someone’s gnuradio branch, clone it and it did work for my machine instead of the master branch of gnuradio which issue thoses errors. Actually, I had already stated that matter here, but issue was not fixed: [http://gnuradio.4.n7.nabble.com/Issue-while-installing-GR-3-7-td46435.html#a46466](http://gnuradio.4.n7.nabble.com/Issue-while-installing-GR-3-7-td46435.html#a46466) Regards, Naceur – View this message in context: [http://gnuradio.4.n7.nabble.com/GRC-issues-with-GNU-Radio-3-7-tp46935p46962.html](http://gnuradio.4.n7.nabble.com/GRC-issues-with-GNU-Radio-3-7-tp46935p46962.html) Sent from the GnuRadio mailing list archive at [Nabble.com](http://Nabble.com). ---
