Marcus,
Thanks for those words of encouragement; based on that I dived
in.
1. Tutorial you mentioned says to clone the repository "git
...". Hmmm, I don't have git, but I can go the website, get a
zip, extract to my working directory; different tool with same
result.
I don't know/think the .zip contains the volk submodule; I'm
currently travelling, so I can't check.
You should get git, anyway (it really makes a lot of sense when
working with out-of-tree modules or source code in general).
2A. Tutorial says to use cmake. Hmmm, google search
for cmake, download, install, and it detects that I have Visual
Studio; it tests that and declares it usable (this is
encouraging), but then barfs on a missing package called Boost.
2B. Google search for Boost turns up a nutritional supplement -
probably not that. Second hit is a set of C++ libraries.
Download, install, try cmake again: same problem - can't find
Boost.
Stuck here for now.
Yeah, finding libraries under windows is a pain. You'll need to
manually tell CMake where to find boost. I know I did that under
Windows once, but can't remember how that looked like :/
Also, I think it'd be a very good idea to use the same boost version
as was used to build the GNU Radio you're using – I don't know which
one that is, though :( you might need to find out yourself by
finding the boost.dlls that came with your GNU Radio installation
and looking at their version.
3. Meanwhile, further on in the tutorial, I will need a tool
called gr_modtool. No gr_modtool.exe found, but I did locate a
.py file. Tried with Python and got this:
python "C:\Program Files\GNURadio-3.7\bin\gr_modtool.py" nm
Name of the new module: how2
Could not find gr-newmod source dir.
Uff, yeah... hm. That's probably one of the rough edges of the
Windows build
try something like
python "C:\Program Files\GNURadio-3.7\bin\gr_modtool.py" nm
"--srcdir=C:/path/to/GNU Radio/share/gnuradio/gr-newmod"
you might have to use a file search program to find the gr-newmod
directory. Sorry, really never tried to do that.
I found a configuration file for location of the
newmod directory, so I tried to override that to a local copy.
No joy - same error.
There was someone on this list in 2014 named PEEL Luke who said
he had gr_modtool working on Windows - I would like to know the
steps.
Also stuck here for now.
in 2014, both gr_modtool and windows support were totally different.
No parallels can be drawn, sorry.
Did some further digging and learned that the
windows binaries that I downloaded were just recently assembled
(i.e. prior to spring of 2016 you had to build it yourself), so
not surpisingly the OOT stuff hasn't been tackled yet. Also, the
hoops he had to jump through were many and varied including
numerous dependencies, so I'm not confident that I could figure
it out just by hacking along.
So, I still wanted to try creating a GRC block. I created a VM
(Ubuntu 16.04) and installed the whole GR stuff there. Next I'll
try that tutorial again.
Either way, we'll definitely look forward to hearing from you!
Best regards,
Marcus
