Thomas, while bootstrapping the gomp-4_0-branch, I ran into this error: ... libtool: compile: build/./gcc/gfortran -Bbuild/./gcc/ -Binstall/x86_64-unknown-linux-gnu/bin/ -Binstall/x86_64-unknown-linux-gnu/lib/ -isystem install/x86_64-unknown-linux-gnu/include -isystem install/x86_64-unknown-linux-gnu/sys-include -m32 -L. -Wall -L../libgfortran -m32 -c src/libgomp/openacc.f90 -fPIC -o .libs/openacc.o build/./gcc/gfortran -Bbuild/./gcc/ -Binstall/x86_64-unknown-linux-gnu/bin/ -Binstall/x86_64-unknown-linux-gnu/lib/ -isystem install/x86_64-unknown-linux-gnu/include -isystem install/x86_64-unknown-linux-gnu/sys-include -m32 -L. -Wall -L../libgfortran -m32 -fsyntax-only src/libgomp/openacc.f90 Fatal Error: Can't rename module file 'openacc_internal.mod0' to 'openacc_internal.mod': No such file or directory make[9]: *** [openacc.mod] Error 1 make[9]: *** Waiting for unfinished jobs.... src/libgomp/openacc.f90:621.6: use openacc_internal, only: acc_get_num_devices_l 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
