Hi Alex,
yes, Qwt is necessary; what OS are you on?
Qwt is kind of a problem child; we need Qwt-qt4, in a version somewhere between 5.2 and 6.2.0.
If you're on Linux (which distro?), what does
pkg-config --list-all|grep -i qwt
tell you¹?
When do you get that error, and could you share it with a bit of context in verbatim?
Best regards,
Marcus
¹ Mine tells me there's
qwt5-qt4 qwt5-qt4 - Qt Widgets for Technical Applications
qwt Qwt6 - Qt Widgets for Technical Applications
qwtmathml qwtmathml - Qwt MathML renderer
Yes, QWT is required, but PyQWT is no longer necessary. What version of GNU Radio are you trying to build?
The gr_filter_design tool still uses PyQWT, so you won't be able to run that, but gr-qtgui can be built and run fine without it.

Hello,
I was able to install PyQt. When I attempted to build gnuradio, it complained that it could not find PyQwt and refused to build the gr-qtgui component. The gnuradio website gives the impression it is not necessary. When I attempted to install Qwt, I got an error QT_STATIC_CONST. I believe that is a necessary step to installing PyQwt.
Is PyQwt necessary to install the gr-qtgui component? If so, has anyone experienced this issue before?
Thanks,
Alex
