Description

The m4 directory just needs to exist. Not sure if git will show it if the directory doesn't contain something, which means I may need to check in the files generated in m4 by autoconf.

The AM_PROG_AR variable is not in the version of automake on CentOS 6.x. The fix may be to use an m4 ifdef

Fixing these gets passed these errors, but then I get this:

It's looking in the wrong location for these libs. I don't know why. I need to verify the cross.sh works for libpibox on Fedora. I'm pretty sure it does. Which makes this error very suspicious.

  • Status changed from New to In Progress
  • Assignee set to Hammel
  • Target version set to 0.11.0
  • % Done changed from 0 to 40

First, libpibox failed due to problems with a missing m4 directory and the referent to AM_PROG_AR. To test fixes I needed to use cross.sh, but this was broken too. The latter took longer to fix than the former but I finally found a common solution for libpibox that works on both CentOS and Fedora (ubuntu be damned - I didn't test there).

Then the same problem arose for pnc (pibox-network-config). The same fixes for the former were applied and to cross.sh. But in this case the cross doesn't work correctly on Fedora. So I have to test for which platform I'm on and set the LDFLAGS slightly differently on the two platforms. But now that fix is in and the rootfs build re-run. Waiting to see if we get further this time...

  • % Done changed from 40 to 50

The fedora build completed, including the meta build for packages. This worked on an RPi 2.

All package updates are checked in. All RPi 2 specific changes are committed and pushed to the mjhammel/rpi2 branch.

Currently updating that branch with fixes required for RPi 2 to fully run on hardware. Then those will be tested on CentOS.

#4 Updated by Hammel 9 months ago

The core and all apps build on CentOS now, except for omxplayer. It fails and I don't know why yet.
