The default behavior is to install the blocks to
<prefix>/share/gnuradio/grc/blocks/ GRC knows to look in that path, so
you must have done something strange to your gnuradio installation.
If you know where you installed the xml block files. You can set the
path in the following two ways (copied from the wiki):
Method 2: Configuration File
Create or edit ~/.gnuradio/config.conf and add the following lines:
[grc]
local_blocks_path=/path/to/my/blocks
The local_blocks_path can contain multiple paths separated by colons:
local_blocks_path=/path/to/blocks1:/path/to/blocks2
Method 3: Environment Variable
Set the GRC_BLOCKS_PATH environment variable to a path that contains
your custom block wrapper. The GRC_BLOCKS_PATH can contain multiple
paths separated by colons: GRC_BLOCKS_PATH=/path/to/blocks1:/path/to/blocks2

Unfortunately this doesn't work because I have no /etc/gnuradio/ . Is
this folder normally created automatically when you install gnuradio?
Can anybody help me?
OS: Kubuntu 10.04
gnuradio from git, branch next.
Thanks,
Thorsten
