Hello, After trying to install GNU Radio over the past few days I’vebeen unsuccessful due to various failures of GNU Radio to build. The latest error is as follows:- Segmentation fault (core dumped)gr-blocks/swig/CMakeFiles/blocks\_swig5\_swig\_doc.dir/build.make:177:recipe for target ‘gr-blocks/swig/blocks\_swig5\_doc.i’ failedmake[2]: \*\*\* [gr-blocks/swig/blocks\_swig5\_doc.i] Error 139CMakeFiles/Makefile2:3254: recipe for target’gr-blocks/swig/CMakeFiles/blocks\_swig5\_swig\_doc.dir/all’ failedmake[1]: \*\*\*[gr-blocks/swig/CMakeFiles/blocks\_swig5\_swig\_doc.dir/all] Error 2Makefile:147: recipe for target ‘all’ failedmake: \*\*\* [all] Error 2make failedExiting Gnu Radio build/install As mentioned, this is the latest error of a series ofmany other errors occurring during previous install/build attempts but whichwould be too numerous to mention here. I’ve tried installing using Marcus’s script from the ShirleyBay server but the install fails near the end when attempting to build asmentioned above. I modified Marcus’s script at one point to get the install torun more successfully although eventually even that modification to a line inthe script fails to lead to a successful overall build but it does appear tobuild further doing that. On this occasion, I’ve tried various distro’s of Ubuntu(12.04 LTS, 14.04 LTS – 32 bit and 15.04 64 bit) but none accommodate theinstall of GNU Radio without some error or other. I feel I have installed prerequisites and so forth andprerequisites from various suggestions in the various threads on other sitesdiscussing the install of GNU Radio on Ubuntu. I should say that I’ve installed GNURadio successfully manytimes in the past, using 12.04 LTS and installing GNU Radio on Windows 7 andthis has been great to use with my Ettus USRP B100 (using UHD) at the time.However, today, some two years later I want to use GNU Radio a lot more andhopefully write modules and develop a SDR UI for my Ettus device but I don’tappear to be having any success at the GNU Radio install which is frustrating. I’ve used so much time up trying to overcome the variousissues, I’m now turning to ask for help as I feel I’ve exhausted every approachI can try with my present knowledge level. All help and guidance is very much appreciated and manythanks in advance. Mark. ---

However, I suggest you just use the gnuradio that comes packaged in the latest ubuntu. ‘apt-get install gnuradio’. If you insist on a source build then I always like to do at least a apt-get build-dep gnuradio on fresh OS installs. (but it’s worth asking yourself if you really need the source build, especially since it’s causing so much grief) ---
