Re: [Discuss-gnuradio] Problem with cmake not finding includes

[Andrew Davis]

Wow, what a coincidence, I just ran into this problem this morning and was about to ask about it right before I saw your post, I too am having the exact same problem on xubuntu amd64. I have not done a git pull for a few days so this problem was not caused this morning by any commit if that helps. 

Thanks,

Andrew

Hi,

I'm porting my real time Doppler correction block from 3.6 to 3.7 but
have come across an issue that when I try to cmake it, I get an error
saying it cannot find the runtime includes. To replicate this I
created a new block ('howto') and tried to cmake that and got the same
error:

# gr_modtool newmod howto
Creating out-of-tree module in ./gr-howto... Done.
Use 'gr_modtool add' to add a new block to this currently empty module.

I've tried to figure out what cmake is actually looking for, but
quickly ran out of enthusiasm for trying to debug cmake
(--debug-output is of very limited help, and my usual method of
'strace' to see what files a process is actually looking for is
thwarted due to the use of pipes/subprocesses). If I look in
/usr/lib/cmake/gnuradio/GnuradioConfig.cmake I see that there is a
line:
GR_MODULE(RUNTIME gnuradio-runtime gnuradio/top_block.h gnuradio-runtime)
which to me implies that it might be looking for top_block.h to check
that runtime include are installed. If I do:

# ls -l /usr/include/gnuradio/top_block.h

-rw-r--r-- 1 root root 4822 Jun  9 20:44 /usr/include/gnuradio/top_block.h


I'm running debian unstable on amd64 with gnuradio-dev (3.7.0-5)
installed.

Any suggestions as to how to fix or debug this issue would be
gratefully received!

Thanks,

Matt
