Re: [Discuss-gnuradio] Gr-Inspector install errors

[Sebastian Müller]

Ok, I think cmake is still finding the older Qwt version, while the new one is installed as well. The file mentioned in the error message (qwt_plot_zoneitem.h) is new in version 6.1.0 and should therefore be found. Did you uninstall Qwt with apt-get before you reinstalled from source? If not, please try that. If this does not help, can you tell me where the files (in particular qwt_global.h) are getting installed on your system? All file paths will be printed when running `sudo make install` at the end of the installation process.

Cheers,

Sebastian

I installed QWT 6.1.0 from the link you provided however, I'm getting the same header file error. Not quite sure what's going on at this point. I've installed qwtplot3d as well as qwt 6.1.0 to make sure I have the necessary dependencies.

This is most likely because of your qwt version. Minimum required version is 6.1.0 (see Readme), while Ubuntu 14.04 has an earlier version in it's repos.

You should install version 6.1.0 on you system, which you can either do by compiling it from sources [1] or upgrading your distro to a more recent version.

Best, Sebastian

Hi Tellrell,

Looks like its a QWTPLOT3D issue, which is a dependency. I tried installing that but I'm having some difficulty there.

What do you mean by 'I tried installing that'? Did you succeed? Or what is the problem if not? Can you specify your OS and version?

 Could NOT find Qt4 (missing: QT_QWTPLOT3D_INCLUDE_DIR QT_QWTPLOT3D_LIBRARY)

This is basically cmake telling you QwtPlot3D cannot be found. Most likely, you need to install this (see above) and it should work.

Cheers,

Sebastian
