Is there a particular reason that you are building an outdated development release? The problem that you point out has been fixed quite a while ago and 2.3.19 includes this fix.

[Gimp-developer] Using Parallel Make
Hi, I recently acquired a new PC with a dual core chip running Kubuntu Feisty Fawn. So when I last tried to build Gimp, version 2.3.18, I used make -j and the build terminated with an error in just a few seconds. If I just use the command make, the build completes successfully in about 10 minutes. Reading up on parallel make, I conclude that the Gimp makefile is not up to snuff for doing a parallel make. Naively perhaps, I think that is a shame because I bet a lot of people would save a lot of time if they could do parallel makes. Has anyone looked at doing parallel builds of Gimp?

Re: [Gimp-developer] Using Parallel Make
"make -j" without a numeric argument will overwhelm most machines fairly quickly in complex makes. Since you're running a dual-core machine, try "make -j3" or "make -j4". This will limit the number of concurrent processes to something reasonable and provide decent load balancing between processing and i/o. (I haven't looked at the gimp Makefiles recently, but running gcc with the -pipe option might help performance, at least on Linux systems--I haven't a clue about Windows systems.)

[Gimp-developer] Using Parallel Make
Looking more closely at what is happening, I notice that when I do a make -j 3 the make stops with the following error message: make[2]: *** No rule to make target `../libgimpthumb/libgimpthumb-2.0.la', needed by `gimp-thumbnail-list'. Stop. If I then do a make, followed by a Control-c in say 5 seconds, followed by a make -j 3 the build will complete successfully yielding a working program. This seems to be repeatable. The total build time is approximately halved and both cpu's are pegged most of the time. Thanks for the suggestion to use -j 3. ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
