I think the distribution and build system needs some improvement. I say that because a disproportionate amount of traffic on this list seems to pertain to building the software from source. It shouldn’t be this hard given the tools that are available. Mike H., N4PLE ---

And I agree that it /should/ be easy. But the thing is, I think that it /is/ easy. However… One issue is that the project has evolved a lot over its lifetime and a lot even in the past year. So that means that a) there’s a lot of bad information out there about working with older releases and b) people want the latest and greatest. So they try one thing, and it only gives them an older version, like 3.6, so they want to update. Without properly removing everything from their system, they try and build from scratch or use on of the build tools Marcus mention, which then causes conflicts. Many of the installation questions are really related to Linux and it just happens to be GNU Radio that’s causing them to run into these OS problems. Tom ---

I use SDR apps such as quisk, qsdr and ghpsdr3-alex which have quite a number of dependencies that help to reduce the number needed by gnuradio. I needed only about 4 to build the latest git on Fedora 20. Once I have built those apps, especially ghpsdr3-alex which details a number of pre-reqs to be installed, it makes light work of building gnuradio. I use 3 cmake scripts, one for x86\_64, one for Ubuntu x86\_64 and one for Ubuntu ARM. # x86\_64 openSUSE and Fedora which use /usr/lib64 #!/bin/sh cmake -DPYTHON\_EXECUTABLE=/usr/bin/python2.7 -DPYTHON\_INCLUDE\_DIR=/usr/include/python2.7 -DPYTHON\_LIBRARY=/usr/lib64/libpython2.7.so -DCMAKE\_INSTALL\_PREFIX=/usr . # Ubuntu x86\_64 which uses /usr/lib #!/bin/sh cmake -DPYTHON\_EXECUTABLE=/usr/bin/python2.7 -DPYTHON\_INCLUDE\_DIR=/usr/include/python2.7 -DPYTHON\_LIBRARY=/usr/lib/libpython2.7.so -DCMAKE\_INSTALL\_PREFIX=/usr . # ARM Ubuntu on Pandaboard, ODROID-X and Parallella-16. #!/bin/sh cmake -DPYTHON\_EXECUTABLE=/usr/bin/python2.7 -DPYTHON\_INCLUDE\_DIR=/usr/include/python2.7 -DPYTHON\_LIBRARY=/usr/lib/libpython2.7.so -DCMAKE\_INSTALL\_PREFIX=/usr -DENABLE\_PYTHON=ON -DENABLE\_VOLK=ON -DENABLE\_GRC=ON .. 73 … Sid.
