I can't reproduce parallel build breakage. But I see another problem: the version string inside mips pbl binary is differ from the version string inside main barebox binary. I suppose that the problem is that current build system handles mips asm files (which are actually use generated compile.h) and c-files in a different way. -- Best regards, Antony Pavlov _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
