Some dependency problems in the Makefiles I would think: + make -j4 /usr/bin/bison -d -p jscyy ./JavaScriptCore/parser/Grammar.y -o DerivedSources/Grammar.cpp > bison_out.txt 2>&1 /usr/bin/perl JavaScriptCore/create_hash_table JavaScriptCore/parser/Keywords.table > DerivedSources/Lexer.lut.h GEN stamp-webkitenumtypes.h /usr/bin/perl JavaScriptCore/create_hash_table JavaScriptCore/runtime/ArrayPrototype.cpp -i > JavaScriptCore/runtime/ArrayPrototype.lut.h /bin/sh: DerivedSources/Lexer.lut.h: No such file or directory make: *** [DerivedSources/Lexer.lut.h] Error 1 make: *** Waiting for unfinished jobs.... Creating hashtable for JavaScriptCore/runtime/ArrayPrototype.cpp Building without "-j4" probably works.
Seems that some of the created files are lacking explicit dependencies. The problem is also that bison will fail and not exit if the output directory does not exist. So the original: /usr/bin/bison -d -p jscyy ./JavaScriptCore/parser/Grammar.y -o DerivedSources/Grammar.cpp > bison_out.txt 2>&1 call would hang ad eternam if DerivedSources did not exist. There are no explicit targets or dependencies to build DerivedSources in the GNUMakefile.am
I don't think this one is an issue any longer, but please feel free to re-open if I'm wrong about that!
