Thomas,
while bootstrapping the gomp-4_0-branch, I ran into this error:
...
libtool: compile: build/./gcc/gfortran -Bbuild/./gcc/

Fatal Error: Can't rename module file 'openacc_internal.mod0' to
'openacc_internal.mod': No such file or directory

make[9]: *** Waiting for unfinished jobs....
src/libgomp/openacc.f90:621.6:

1
Fatal Error: Can't open module file 'openacc_internal.mod' for reading at (1):
No such file or directory
make[9]: *** [openacc.lo] Error 1
...
AFAIU, we compile fopenacc.f90 twice in the same working directory, once using
this rule to obtain openacc.mod:
...
%.mod: %.f90
$(FC) $(FCFLAGS) -fsyntax-only $<
...
And once more to obtain openacc.lo.
AFAIU, given the absence of -J, both will use temporary file fopenacc.mod0,
which explains the error.
If we first build fopenacc.mod, we'll produce openacc.mod file, which is then
overwritten by building fopenacc.lo. If we first build fopenacc.lo, we already
have fopenacc.mod, and we'll not build another openacc.mod. So in both cases, we
use the fopenacc.mod produced by building openacc.lo.
It's only when we try to build both simultaneously that we can run into his
error.
And, we don't need to build both, since building fopenacc.lo already produces
fopenacc.mod.
This patch tells make that building fopenacc.lo produces fopenacc.mod, and that
fixes the error.
Committed as obvious.
Thanks,
- Tom
