Out-of-tree module build fails for lack of Doxygen, despite -DENABLE_DOXYGEN=OFF

GNU Radio

I first used gr_modtool.py to successfully create my out-of-tree module
on an Ubuntu 12.04 LTS x86 system (GNU Radio 3.6.4.1).

I am now building my module on an Ubuntu system that does not have
/usr/bin/doxygen (the new system is based on 12.04 LTS for Arm).

Despite specifying -DENABLE_DOXYGEN=OFF, the build fails thusly:

cmake -DENABLE_DOXYGEN=OFF …/

I have duplicated the above failure on the Ubuntu 12.04 LTS x86 machine
by first doing “sudo mv /usr/bin/doxygen /usr/bin/doxygen_tmp” to
simulate no doxygen installed.

I am trying the same experiment on the gnuradio tree (3.6.4.1) on Ubuntu
12.04 LTS x86; if it builds, maybe I can compare various files to see
the difference.

But maybe one of you can beat me to the solution or a work-around :slight_smile:

Thanks in advance,

The gnuradio tree build was able to handle this test, so that is good.

I found a work-around by a hostile takeover of the FindDoxygen module of
Cmake:

(with sudo as needed)

echo ‘set(DOXYGEN_FOUND “NO”)’

/usr/share/cmake-2.8/Modules/FindDoxygen.cmake

echo ‘set(DOXYGEN_DOT_FOUND “NO”)’

/usr/share/cmake-2.8/Modules/FindDoxygen.cmake

I will leave it to the smarter people of this list to find a better
solution. Cheers!

Hi Tim,

Can you open up a ticket on the gnuradio.org wiki with this
information? That will help us track it better.
