Greetings, Lately, I have been having increasing difficulties with building gnuradio successfully on the Ubuntu PPA builders. I think the problems is that the builds run in emulated environments and the builder is not as powerful as a modern desktop. Consequently, it will die on one of the swig files, either because of a 150 minutes timeout or it simply runs out of memory. Initially, I only had this problem for some armhf builds and ignored it, but now with 3.7.2.1 amd64 builds are failing too ☹ This could be due to reorganization of the build hosts but it is pretty much out of my control. I can try to request a rebuild hoping for a different build host from the pool, but it is a 10-15 hour wait and so far didn’t help. Is there anything we can do in the gnuradio end to improve this?

I’ve tried my best to split up the swig files to minimize the memory footprint and compile time, but it’s just too large a project. Johnathan and I have been kicking around some ideas that might be able to help in the far future. But for right now, I haven’t found anything that can reduce the build issues further. I tried to go in an find as many instances of %include that can be replaced by %import, but there really weren’t that many. One thing to do with the memory issue is to set make to only build with 1 thread (no parallelism). It’ll take longer over all, but it will keep the memory footprint pretty small. The main problem is when swigging multiple blocks\_swigX files at the same time. Tom ---

Hi Tom, Thanks for the reply and the clarification. AFAIK the builds are already running single threaded although I am not 100% sure. I managed to get the i386 and amd64 builds done this time by retrying the failed builds one more time. I guess I was lucky the third time. One solution might be to set up own PPA builder but I’m not quite there yet. Alex
