Hi! In r12-6498 I've added $(version_dep) to BUILT_SOURCES, previously version_dep on Linux used to be a file in $(srcdir), but with my changes it is a generated file in the object directory (preprocessed version of the $(srcdir) file) and I thought generated files belong to BUILT_SOURCES so that they are cleaned up etc. For Linux that is fine, but it broke parallel builds on Solaris. BUILT_SOURCES is a special variable for automake where automake ensures that for make all, make check and make install all those $(BUILT_SOURCES) are generated before actually starting building in parallel the various object files. That way we can avoid hacks like: $(patsubst %.F90,%.lo,$(notdir $(filter %.F90,$(prereq_SRC)))): kinds.inc c99_protos.inc $(patsubst %.c,%.lo,$(notdir $(filter %.c,$(prereq_SRC)))): kinds.h $(patsubst %.f90,%.lo,selected_real_kind.f90): selected_real_kind.inc $(patsubst %.f90,%.lo,selected_int_kind.f90): selected_int_kind.inc $(patsubst %.F90,%.lo,ieee_exceptions.F90): fpu-target.inc $(patsubst %.F90,%.lo,ieee_arithmetic.F90): fpu-target.inc ieee_exceptions.lo $(patsubst %.c,%.lo,fpu.c): fpu-target.h which makes those dependencies explicit but hides it from automake, so that it doesn't throw away its rules for those object files. On Solaris, $(version_dep) contains gfortran.ver and gfortran.ver-sun. gfortran.ver is like on Linux, it can be in $(BUILT_SOURCES), but unfortunately gfortran.ver-sun depends on all the object files being compiled already, so if gfortran.ver-sun appears in $(BUILT_SOURCES), the BUILT_SOURCES function of ensuring the generated files are generated before building object files is gone, almost everything is built before all-am is entered and there are no explicit dependencies that e.g. *.F90 files depend on kinds.inc etc.
So, this change reverts that mistake and instead adds $(version_dep) to what is removed during make clean (clean-local in particular). The reversion committed under the reversion of our own patches policy, the clean-local change considered obvious, committed to trunk. 2022-01-14 Jakub Jelinek <ja...@redhat.com> PR libfortran/104006 * Makefile.am (BUILT_SOURCES): Don't include $(version_dep).
