Can no longer build packages for PPA

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 :frowning:
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?

Hi Alex,

I don’t think there is, unfortunately. 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.

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.
