Hey Marcus, I am trying to build my own custom block in gnuradio, with the help of following link “[http://gnuradio.org/redmine/projects/gnuradio/wiki/OutOfTreeModules](http://gnuradio.org/redmine/projects/gnuradio/wiki/OutOfTreeModules) and [https://gnuradio.org/redmine/projects/gnuradio/wiki/OutOfTreeModulesConfig](https://gnuradio.org/redmine/projects/gnuradio/wiki/OutOfTreeModulesConfig) [Making your own signal processing blocks in GNU Radio - YouTube](https://www.youtube.com/watch?v=BW8o9ZgFJ5I)” But i am stuck with an error while cmake abhishek@abhishek-Inspiron-N5110:~/gr-howto/build$ cmake …/ – The CXX compiler identification is GNU 4.8.2 – The C compiler identification is GNU 4.8.2 – Check for working CXX compiler: /usr/bin/c++ – Check for working CXX compiler: /usr/bin/c++ – works – Detecting CXX compiler ABI info – Detecting CXX compiler ABI info - done – Check for working C compiler: /usr/bin/cc – Check for working C compiler: /usr/bin/cc – works – Detecting C compiler ABI info – Detecting C compiler ABI info - done – Build type not specified: defaulting to release. – Boost version: 1.55.0 – Found the following Boost libraries: – filesystem – system – Found PkgConfig: /usr/bin/pkg-config (found version “0.26”) – checking for module ‘gnuradio-runtime’ – package ‘gnuradio-runtime’ not found – Could NOT find GNURADIO\_RUNTIME (missing: GNURADIO\_RUNTIME\_LIBRARIES) – checking for module ‘cppunit’ – found cppunit, version 1.13.1 – Found CPPUNIT: /usr/lib/x86\_64-linux-gnu/libcppunit.so;dl CMake Error at CMakeLists.txt:98 (message): GnuRadio Runtime required to compile howto – Configuring incomplete, errors occurred!

Do you have GNU Radio correctly installed? this looks like you don’t, or you have an old installation (GNU Radio 3.6). Check by running “gnuradio-config-info --version”. ---

Hey Marcus, My after this command “gnuradio-config-info --version” i got 3.7.2.1 later i type “pkg-config --modversion gnuradio-runtime” i got abhishek@abhishek-Inspiron-N5110:~$ pkg-config --modversion gnuradio-runtime Package gnuradio-runtime was not found in the pkg-config search path. Perhaps you should add the directory containing `gnuradio-runtime.pc’ to the PKG\_CONFIG\_PATH environment variable No package ‘gnuradio-runtime’ found what does this exactly mean…? Thanks in advance, Abhishek ---

Did you make and make install your out-of-tree module already? Does GRC look into the place where you install into when looking for block definitions? Generally, I’d like to point you to the guided Tutorials, which are a bit easier to follow and currently better maintained: [https://gnuradio.org/redmine/projects/gnuradio/wiki/Guided\_Tutorials](https://gnuradio.org/redmine/projects/gnuradio/wiki/Guided_Tutorials) Best regards, Marcus ---

yaa I have done make and make install both, even my xml block is created inside the grc folder which I had shown through attachment. Later i copied that howto\_square\_ff.xml file to path “/usr/share/gnuradio/grc/blocks” where all my blocks are stored. This helped me to get square\_ff block in grc, but while running an example using that block i am stuck with an error ImportError: libgnuradio-runtime-3.7.7git.so.0.0.0: cannot open shared object file: No such file or directory On Mon, Mar 16, 2015 at 2:05 AM, Marcus Müller [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) ---
