--- Comment #21 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
That is make -j48 from where?
Toplevel, or the libgfortran build dir, or toplevel make -j48
all-target-libgfortran or make -j48 maybe-all-target-libgfortran?
>>From what I can see, toplevel all-target-libgfortran should do make all in =
the
libgfortran build dir:
ARGET-target-libgfortran=3Dall
maybe-all-target-libgfortran: all-target-libgfortran
all-target-libgfortran: configure-target-libgfortran
        @: $(MAKE); $(unstage)
        @r=3D`${PWD_COMMAND}`; export r; \
        s=3D`cd $(srcdir); ${PWD_COMMAND}`; export s; \
        $(NORMAL_TARGET_EXPORTS)  \
        (cd $(TARGET_SUBDIR)/libgfortran && \
          $(MAKE) $(BASE_FLAGS_TO_PASS) $(EXTRA_TARGET_FLAGS)   \
                $(TARGET-target-libgfortran))
and all: in the libgfortran Makefile should be:
all: $(BUILT_SOURCES) config.h
        $(MAKE) $(AM_MAKEFLAGS) all-am
(in your case with the ls -l added above it).
Perhaps also above the ls do
        echo all in libgfortran, BUILT_SOURCES is $(BUILT_SOUCES)
What version of GNU make are you using?
I just don't understand how it could start building the object files etc.
which is done from all-am before actually ensuring all those $(BUILT_SOURCE=
S)
like kinds.h exist.=
