Re: [Discuss-gnuradio] Building on ODroid C2 running CentOS 7 report.

[Anon Lister]

Nice. I just did an x64 el7, so I only had to source build a few packages. I'd be curious to know what kind of performance you get on that platform.

For deps, you may be able to harvest a list from the the work Geoff has been doing for the windows build scripts[1]. He also lists the versions used.

I have been successful in getting CentOS 7 onto an ODroid C2.  This is the AArch64 version; armv8, 64-bit.

I did run into a bug in build-gnuradio, however.  The logic that determines the release number for CentOS/RHEL/SL 6 is flawed.  The logic looks for the pattern '*elease*6*' in /etc/redhat-release; however, on the CentOS 7 AArch64 version, here's what is in that file:
address@hidden ~]$ cat /etc/redhat-release
CentOS Linux release 7.2.1603 (AltArch)
address@hidden ~]$

This incorrectly drives the script to try the prereqs for CentOS/RHEL//SL 6 instead of 7.  Changing the test to '*elease*6.*' fixes it.

I don't quite have a full GUI build of GNURadio yet since I've been hand-building the EPEL dependencies one by one, and now I have another list of deps to build..... (There is no EPEL for CentOS7 on any arm, 32 or 64-bit, yet).  The build, not counting GRC and a few other GUI modules, takes over 6 and a half hours on the C2 and eats swap for lunch (a couple of the wrapper files need >2GB of virt during the build, and the C2 only has 2GB of RAM).

I'll give a fuller report once I have a successful GUI build, and/or when EPEL is available for AArch64......
