OE-Core Yocto gcc timeout

I’ve been thrashing around trying to get the upstream OE to build an image for me. Today I finally made a concerted effort over a few hours to dive deep and do this right. It turns out I was using the “old” OE repos when I should have been using the “new” build system from the Yocto Project. Their documentation is excellent but still, my first build failed.

What’s this? The GCC recipe failing because of a network timeout? Oddly enough it actually downloaded some of the sources but not all of ’em.

| svn: REPORT of '/svn/gcc/!svn/vcc/default': Could not read response body: connection was closed by server (http://gcc.gnu.org)
NOTE: package gcc-cross-initial-4.6.1+svnr175454-r10: task do_fetch: Failed
ERROR: Task 5 (/home/build/poky-edison-6.0/meta/recipes-devtools/gcc/gcc-cross-initial_4.6.bb, do_fetch) failed with exit code '1'
ERROR: '/home/build/poky-edison-6.0/meta/recipes-devtools/gcc/gcc-cross-initial_4.6.bb' failed

At this point I just tried again and it failed in the same place but had checked out more of the code. A quick search turns up a similar error is common when checking out code from SVN servers over HTTP. Apache just has a tendency to timeout when checking out large repositories with mod-svn. The suggested fix is to increase the timeout value in your Apache configs … except these configs are on the GNU web servers and we can’t change them.

What we can change though is the protocol bitbake uses when getting the sources. Just change the proto from ‘http’ to ‘svn’ in the SRC_URI in gcc-4.6.inc (found at /meta/recipes-devtools/gcc/gcc-4.6.inc and we’re almost good. It’ll look like this when you’re done.

SRC_URI = "svn://gcc.gnu.org/svn/gcc/branches;module=${BRANCH};proto=svn

It still timed out for me a few times but it ran for much longer than the HTTP protocol option. HTTP timed out after about 10 minutes, SVN made it almost an hour before timing out … You’d think there would be a tarball of these sources mirrored somewhere so we didn’t have to kill the GNU SVN servers on every fresh build. Something to look into I guess. Either way gcc is building now, hopefully I’ll have a build running soon …

UPDATE: With some advice from Scott below I used the poky distro by including: DISTRO="poky" in my local.conf file. As promised bitbake then doesn’t try to check out the gcc svn repository directly from gnu.org. Instead it grabs a tarball from one ob the Yocto mirrors and the build takes mere minutes. Thanks Scott!

  1. One advantage you get when you use the complete Yocto build system and default distro (Poky) is that our default meta-yocto layer includes a PREMIRROR which causes the build system to attempt to download tarballs from our mirror before hitting the upstream.

    You can take advantage of this using your current distro by copying our PREMIRRORS and MIRRORS section into your distro config file:
