Re: [Discuss-gnuradio] cmake build gnuradio on FreeBSD

[Andrew Davis]

Yeah, I asked about that earlier, for some reason qwt is hard coded to 
/usr/include in the configure script. It really should just use the 
system path and not check just one predefined path, this also is a 
problem on Gentoo and any other OS that uses "/usr/local/" instead of 
"/usr/".

What the configure script should do is make two C programs:

#include < qwt/qwt_math.h >

and 

#include < qwt5/qwt_math.h >

then
 see which compiles to find the qwt include folder name, or just not 
check and assume the first as that is what the code expects and most 
systems do anyway. Checking breaks more systems than it helps at this 
point, if anyone uses qwt5 directory they should just change it 
themselves.

 I do not find anything in the README about qt4 or qwt but they seem
to be required for gr-qtgui.

 I used portinstall to install py27-qt4 and several hours and 57 packages
later, cmake could find qt4.

 Then I installed py27-pyqwt and it also installed qwt-5.2.2. Cmake
still would not find qwt. (QWT_FOUND = FALSE).

 I finally tried adding the QWT_INCLUDE_DIRS line below and cmake now
finds qwt and shows gr-qtgui to be built. Trying that next.

   cmake \
     -DCMAKE_INSTALL_PREFIX=$GR_PREFIX \
     -DQWT_INCLUDE_DIRS=/usr/local/include/qwt \
     ../
