Re: [Discuss-gnuradio] Installation of gr-radar

[Sebastian Müller]

Hello Talha,

Qt and Qwt are different softwares. Gr-radar depends on Qt4 and Qwt6.
The error has to do with Qwt. I guess you don’t have the correct
version of Qwt installed.

PS: Please avoid to send pictures to mailing lists, since this takes
up space in everyone's mailbox. Better use a service like imgur and
post the link to the picture in your mail :)

Best,

Sebastian Müller
