[Gimp-developer] Building GIMP on OSX 10.9

[scl <scl gplus gmail com>]

Hi,

I'm building GIMP on OS X 10.9 with an updated version
of Clayton Walker's JHBuild script. The command I use is
JHB=gimp GIMP_SDK=10.9 jhbuild build gimp-osx

Now that I have all my dependencies built, building GIMP
itself fails with the following messages:



Making all in core
make[4]: warning: -jN forced in submake: disabling jobserver mode.

The following error is repeated many times until the build breaks with
the message 'Too many errors emitted, stopping now [-ferror-limit=]':

I have glib 2.39.1 installed and the sources I build with are
in [GIMP's osx-build branch] plus Simone's and su_v's patches
to treat C files as Objective C files. However, this doesn't
seem to solve the problem.

Does anybody have a clue how to fix these errors?

Thank you in advance,

Sven
