Description Caleb Tennis 2004-03-01 03:51:37 UTC

Version:            (using KDE KDE 3.2.0)
Installed from:    Gentoo Packages
Compiler:          gcc 3.3 
OS:          Linux

There are parallel make errors in kdemultimedia/arts/gui.

Some of the .cc files are dependent on .h files, which must first be created from running mcop on the .idl files.

For example, arts/gui/common/genericguifactory_impl.cc relies on artsgui.h, which is built after running mcop on artsgui.idl.  However, for users using make with the "-j N" option, in most cases the compilation for genericguifactory_impl.cc gets run before mcop has had a chance to run, causing the build to fail.

(This also seems to persist with some of the other .idl files in the the arts/ subdirectory, and it may manifest itself in other subdirectories as well.)

Solution:

I can either recommend to add a "-j1" to the compiler flags in the Makefile to override the parallel make behavior, or to add a .NOTPARALLEL argument to the makefile to disable the parallel building.  There may be other, smarter, options as well.

I've committed this (NOTPARALLEL) fix for HEAD.  I'll plan to fix it in the 3.2 branch too as long as nobody complains about it in head.

or you fix it the right way instead of adding nonsense work arounds?
