Hi Robert, I’m pretty sure you have a corrupt qwt installation on your machine (which is also 90% the issues users have with gr-inspector). The file libqwt-qt4.so.5 does not seem to come from qwt-6.1.0 source build, but from the debian package 'libqwt5-qt4‘. If you just use a symbolic link and trick cmake into finding this file, things might go wrong down the road since this is a qwt 5 library! I would avoid using symlinks for this purpose at all. See my other comments below. Am 9. April 2018 um 20:26:36, Robert Stanford (address@hidden) schrieb:
Please uninstall all qwt related packages and files from your machine. As mentioned above, there seems to be other (broken) qwt installations. This is not an easy task, so please take some time to clean everything up!
This is normal if you didn’t build GNU Radio from source.
You are symlinking a qwt directory to a qwtplot3d directory. This does not make sense to me and will most likely cause problems. All the files you need should be in /usr/include/qwtplot3d-qt4 and be provided by ‚libqwtplot3d-qt4-dev‘ [1]. If they are not there, something is wrong with your system. If the files are there, please share the output of cmake without symlinking beforehand.
Same thing here libqwt-qt5.so.5 is most likely no file from qwt-6.1.0. The library that you need is in /usr/lib/libqwt.so and is provided by ‚libqwt-dev‘ [2]. If not, again, something is wrong with your system.
This should also not be necessary. What is the error if you don’t do this?
Yes, from the points I mentioned above I don’t think you’re getting a successful build from here on.
