sane-backends: build takes forever

Reported by: dylanarena@… Owned by: macports-tickets@…
Priority: Normal Milestone:
Component: ports Version: 2.0.3
Keywords: Cc: aguynamedryan+sane@…, neverpanic (Clemens Lang), mowerm@…
Port: sane-backends

Description (last modified by neverpanic (Clemens Lang))

I have a brand-new MacBook Pro running 10.7.2. I wanted to install GIMP, so I installed MacPorts from the AppStore and then called "sudo port install gimp" from Terminal. I saw a huge list of dependencies, which MacPorts diligently chipped away at for hours. But it seemed to have hung up at the following point in the process:

--->  Fetching archive for sane-backends
--->  Attempting to fetch sane-backends-1.0.22_1.darwin_11.x86_64.tbz2 from http://packages.macports.org/sane-backends
--->  Fetching sane-backends
--->  Attempting to fetch sane-backends-1.0.22.tar.gz from http://distfiles.macports.org/sane-backends
--->  Verifying checksum(s) for sane-backends
--->  Extracting sane-backends
--->  Applying patches to sane-backends
--->  Configuring sane-backends
--->  Building sane-backends

It had been a few hours, so I hit control-C and then called "sudo port install gimp" again. Happily, this time the list of dependencies was very short:

--->  Dependencies to be installed: xsane sane-backends

So I left the computer to run overnight. But when I returned to my computer this morning I saw that it had been hanging at the following line for at least ten hours:

--->  Computing dependencies for gimp
--->  Dependencies to be installed: xsane sane-backends
--->  Building sane-backends

Can anyone help me diagnose the problem?

Thanks very much for your time, Dylan

Please remember to use WikiFormatting for shell output, set the port field and Cc the maintainer.

Can you attach the logfile pointed to by port log sane-backends? Also, do you see extensive memory usage while the process runs and does everything get very slow?

Summary: "sudo port install gimp" hangs forever on "Building sane-backends"sane-backends: build takes forever

Replying to cal@…:

Can you attach the logfile pointed to by port log sane-backends?

port log sane-backends prints the contents of the logfile. If you want the location of the logfile, use port logfile sane-backends.

I can confirm this. My logfile is attached.

Same deal: port install gimp ... Building sane-backends takes forever.

Same problem for me. Log attached, seems that build gets hung at

Bummer. The only thing I can think of is that maybe there's a deadlock situation arising from building in parallel.

Some googling reveals that libtool might be upset since the phrase "Waiting for $lockfile to be removed" appears here and right below it suggests not doing a parallel build.

I've removed parallel building from the Portfile.

I couldn't recreate the problem on my end, so I can't verify my proposed patch.

Concerning your patch, when I removed the line for "use_parallel_build", I still ened up at "Waiting for $lockfile to be removed". When I changed the line to

use_parallel_build          no

the build succeeded, and gimp was subsequently installed.

Is there anything else I need to do to get the patch committed and this ticket closed? Thanks!

Resolution: fixed
Status: newclosed

Sorry for the delay, r94676. A revision bump was not needed, because the list of installed files didn't change and it you were hit by this bug you can't have a sucessfully installed sane-backends port and thus don't need a rebuild.
