[Discuss-gnuradio] buildroot installation not generating/placing .pc files

[gutelfuldead]

Hey,

I am working on an embedded system build (zedboard) using buildroot that is installing GNURadio and a handful of OOT Modules.

The entire system builds without errors with options:
* gnuradio
	* blocks support
	* ctrlport support
	* gr-fec support
	* python support
		* gr-utils support
	* gr-analog support
	* gr-channels support
	* gr-digital support
	* gr-fft support
	* gr-filter support
	* gr-flex support
	* gr-trellis support

I then created the config and mk files to install gr-iio. However as buildroot attempts to make and install it to the target system I receive the following error:

				CMakeLists.txt:120 (find_package)

The closest solution I can find to this problem is in ( https://github.com/gnuradio/gr-tutorial/issues/8 ) which was resolved by updating GNU Radio to a version that is downstream of my current version (3.7.9.1). Has anyone experienced similar issues or know how to force GNU Radio to generate and place the appropriate .so files?

Thanks.
