Over time, I've accumulated a considerable library of gnuradio-companion designs, and found that
the few designs I've spot checked so far don't load correctly under 3.7. An example
dspdev.2035> gnuradio-companion correlator.grc
linux; GNU C++ version 4.6.3; Boost_104800; UHD_003.005.002-65-g265daa58
<<< Welcome to GNU Radio Companion v3.6.4.1-1280-g0a8078a5 >>>
Loading: "correlator.grc"
>>> Error: Block key "gr_vector_source_x" not found in Platform - grc(GNU Radio Companion)
Traceback (most recent call last):
File "/usr/local/bin/gnuradio-companion", line 70, in <module>
try: gtk.window_set_default_icon(gtk.IconTheme().load_icon('gnuradio-grc', 256, 0))
GError: Icon 'gnuradio-grc' not present in theme
I realize the APIs structure has changed, and for hand coded python blocks, I've
made the necessary changes. The .grc designs are more painful to deal with here, since
it would seem that they have to be substantially re-entered into gnuradio-companion. With
the design not rendering due to missing blocks, there isn't much of a trail of breadcrumbs
to reconstruct the designs from.
Is there a conversion program or some trick I'm missing? Figured I would ask, before
investing the time to re-enter the designs I really need.
Host platforms are 64 bit Ubuntu machines, running 12.04, 12.10. Last git pull og gnuradio
was on May 21, with the 'old' version of gnuradio 3.6 entirely wiped from /usr/local before
compile/install of 3.7.
