New submission from Gregory P. Smith: If you do a make -j12 test or make install before having run a separate 'make all' the build _can_ fail trying to build pgen. (it seems to be parallel make related, it won't always fail)
Even if you have run a separate 'make all', the make test and make install steps are likely to rebuild a ton of stuff and rerun the profile generation stage. Making the suggested "make, make test, make install" process effectively useless or at least take 3x longer than it should. something along the lines of: oss/cpython$ make -j12 install gcc -pthread -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes Parser/acceler.o Parser/grammar1.o Parser/listnode.o Parser/node.o Parser/parser.o Parser/parsetok.o Parser/bitset.o Parser/metagrammar.o Parser/firstsets.o Parser/grammar.o Parser/pgen.o Objects/obmalloc.o Python/mysnprintf.o Python/pyctype.o Parser/tokenizer_pgen.o Parser/printgrammar.o Parser/pgenmain.o -lpthread -ldl -lutil -o Parser/pgen Parser/grammar1.o: In function `PyGrammar_LabelRepr': /home/gps/oss/cpython/build27/../2.7/Parser/grammar1.c:35: undefined reference to `__gcov_indirect_call_profiler' Parser/grammar1.o: In function `PyGrammar_FindDFA': /home/gps/oss/cpython/build27/../2.7/Parser/grammar1.c:13: undefined reference to `__gcov_indirect_call_profiler' Parser/grammar1.o:(.data+0x80): undefined reference to `__gcov_merge_add' Parser/grammar1.o: In function `_GLOBAL__sub_I_65535_0_PyGrammar_FindDFA': /home/gps/oss/cpython/build27/../2.7/Parser/grammar1.c:57: undefined reference to `__gcov_init' ... a bunch more similar errors omitted ...
