Installing gr-my-basic files

Hi all,While following instructions given at adding a
new block I faced following problem.sudo ./bootstrap executed well.But
sudo ./configure gave following error:
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
youinstalled software in a non-standard prefix.
Alternatively, you may set the environment variables
GNURADIO_CORE_CFLAGSand GNURADIO_CORE_LIBS to avoid the need to call
pkg-config.See the pkg-config man page for more details.
I used following commandexport
and then sudo ./configurebut it again gives the same error.
Please suggest what should do now.

What instructions are you referring to? Those build commands refer to
autotools toolchain, which GNU Radio no longer uses.

You should be using CMake, as detailed on this page:
