installation of GNU radio

[jaskirat singh]

sir,

i have been installing GNU radio on fedora. after giving the ./bootstrap and ./configure command in gnuradio-core,it works fine but as i move to make it shows the following error.....

 

"checking for FFT3F...configure: error: Package requirements (fftw3f >=3.0) were not met:

 

No package 'fftw3f' 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 FFTW3F_CFLAGS and FFTW3F_LIBS to avoid the need to call pkg_config. "

 

So, kindly suggest me what should i do .I have already installed all prerequisites packages need before installaion of gnu radio.
