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.
# cd gr-howto
# ls
apps cmake CMakeLists.txt docs grc include lib python swig
# mkdir build
# cd build/
# cmake ../

CMake Error at CMakeLists.txt:98 (message):

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
