I am planning to update an OOT module I wrote 4 years ago. I setup a laptop with a fresh install of Ubuntu 20.04 to use for development. I installed GNU Radio 3.8, but then I decided to go with 3.9, so I removed 3.8, and installed 3.9 from the PPA. Then I ran modtool newmod streamx ... cd streamx modtool add ... modtool bind ...
and then tried mkdir build cd build cmake ../ I didn't have cmake, so I installed that, and then doxygen, and then some others. Still getting errors so I installed ALL the dependencies for building GNU Radio as described here https://wiki.gnuradio.org/index.php/UbuntuInstall#Focal_Fossa_.2820.04.29. I'm still getting the following errors from cmake <...> -- Checking for module 'mpir >= 3.0' -- No package 'mpir' found -- Could NOT find MPIR (missing: MPIRXX_LIBRARY MPIR_LIBRARY MPIR_INCLUDE_DIR) <...> -- Python checking for pygccxml - not found <...> CMake Error in lib/CMakeLists.txt: Imported target "gnuradio::gnuradio-runtime" includes non-existent path "/include" in its INTERFACE_INCLUDE_DIRECTORIES. Possible reasons include: So, do I need mpir and pygccxml? If yes, where to find them and how to install? How do I investigate the missing /include? I can see the include directory in my new streamx module, it's exactly where modtool put it. Thanks, Gavin UbuntuInstall - GNU Radio<https://wiki.gnuradio.org/index.php/UbuntuInstall#Focal_Fossa_.2820.04.29> Building GNU Radio on Ubuntu Linux []. GNU Radio works well on all Ubuntu versions from 10.04 upward. It is also possible to install GNU Radio on older releases of Ubuntu (see #Building_GNU_Radio_on_Legacy_Ubuntu).However, we may not be able to provide sufficient support for legacy OS. wiki.gnuradio.org InstallingGR - GNU Radio<https://wiki.gnuradio.org/index.php/InstallingGR> >From Binaries []. The recommended way to install GNU Radio on most platforms >is using already available binary packages (see Ubuntu PPA Installation).For >some platforms there are no binaries provided by available package managers or >the GNU Radio project. wiki.gnuradio.org
