hello everybudyy ``` i am try to install airprobe for gsm spectrum decoding but i ``` found this problem in gsm reciver installation …i got such a message checking for GNURADIO\_CORE… configure: error: Package requirements (gnuradio-core \>= 3) were not met: No package ‘gnuradio-core’ found Consider adjusting the PKG\_CONFIG\_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables GNURADIO\_CORE\_CFLAGS and GNURADIO\_CORE\_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. can you help me how can i solve it . i am using gnu radio 7.2 ## help me … _Thanks and regard:_ _MR.Maheshkumar P._ _call @ 9662784649_ ---
