Re: [Discuss-gnuradio] Blocks missing from GRC after pre-cog installatio

I cannot figure out the source of the problem. I don't have multiple installations of gnuradio. While I'm installing gnuradio and grextras (either by the installation script from gnuradio.org website or by manually), I run git clone commands in ~/Downloads directory. Thus I have gnuradio and grextras folders in ~/Downloads folder. So, in the usual way I proceed to install, and they are properly installed in /usr/local/ . I run GRC and get all the blocks. I attached the screenshot. Then I run git clone command for pre-cog in ~/Downloads folder, so I have a pre-cog folder in ~/Downloads. I then proceed to install it in usual manner (mkdir build, cmake, make etc.) and it is properly installed. Then if I run GRC, blocks are missing, those that start with gr_*.xml. I have attached the screenshot too.

Would you perhaps have multiple installs of gnuradio both in /usr and
/usr/local? That could be one issue

Also, while its ok to put gnuradio in /usr and grextras and pre-cog into
/usr/local. You will need to set the GRC_BLOCKS_PATH environment
variable to have entries for both block paths. The paths would be
your_install_prefix/share/gnuradio/grc/blocks
