Additional research showed, that same package, compiled standalone goes pretty good. Even, manual compile in /var/tmp/portage after error in emerge, seems to pass this error, and compile very well. If it could be of any use, here is my make.conf file (comments removed): USE="-gnome" CHOST="i686-pc-linux-gnu" CFLAGS="-mcpu=i686 -O3 -pipe" CXXFLAGS="-mcpu=i686 -O3 -pipe"
The bugs.kde.org entry linked from the forum post suggests this is the fault of multithreaded make (make -j2). That is the gentoo default setting (MAKEOPTS="-j2" in make.globals). It tallies well with your report. Please try putting MAKEOPTS="-j1" in make.conf and running emerge kdevelop. Errors caused by using make -j2 have been reported before (in kde apps in general), I'm going to inquire if this is really necessary on non-smp systems...
Yes, that worked for me.. I had the same issue and I changed my MAKEOPTS flag to -j1 and it compiled perfectly.
Good. Mechanic, can you test this?
same problem and solution for kdevelop-2.1.3, with MAKEOPTS="-j2" it doesn't compile with same error, with MAKEOPTS="-j1" everything works fine.
OK, then I'll enforce -j1 in the ebuild.
