John,
what if you move some parameters to CPPFLAGS and CXXCPPFLAGS (see the
new configure command line below)
Thanks, Gilles, that did in fact work for 3.3.4. I was writing up an email
when yours came in, so I'll move my response to here:
Jeff, I've now tried several things, so I have some ideas, and I can
send you one
or more config.log's, as you wish. Will mention options at end of this.
First, I got the compile to work, below, with -DOPAL_STDC_HEADERS added
to CFLAGS,
but then subsequent packages failed to build for not knowing ptrdiff_t.
So it
appeared that I would have to have -DOPAL_STDC_HEADERS set for all dependent
packaged. So then I configured with CPPFLAGS set to the same as CFLAGS,
and
for 3.1.4, it configured, built, installed, and dependent packages did
as well.
For 4.0.1, it did not.
Some responses below:
A few notes on your configure line:
'/Users/cary/projects/ulixesall-llvm/builds/openmpi-4.0.1/nodl/../configure' \
--prefix=/Volumes/GordianStorage/opt/contrib-llvm7_appleclang/openmpi-4.0.1-nodl
\
CC='/Volumes/GordianStorage/opt/clang+llvm-7.0.0-x86_64-apple-darwin/bin/clang'
\
CXX='/Volumes/GordianStorage/opt/clang+llvm-7.0.0-x86_64-apple-darwin/bin/clang++'
\
The MPI C++ bindings are no longer built by default, and you're not enabling
them (via --enable-mpi-cxx), so you don't need to specify CXX or CXXFLAGS here.
Thanks for this and your other comments on how to minimize our configuration
line. Will adopt.
FC='/opt/homebrew/bin/gfortran-6' \
F77='/opt/homebrew/bin/gfortran-6' \
F77 is ignored these days; FC is the only one that matters.
Thanks. Will clean up.
CFLAGS='-fvisibility=default -mmacosx-version-min=10.10
-I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include
-fPIC -pipe -DSTDC_HEADERS' \
Do you need all these CFLAGS? E.g., does clang not -I that directory by
default (I don't actually know if it is necessary or not)? What does
-DSTDC_HEADERS do?
-fvisibility=default: found needed for Boost, and kept through entire chain.
May revisit.
-mmacosx-version-min=10.10: Gives a build that is guaranteed to work back
through Yosemite, when
we distribute our binaries.
-I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include:
Apple is now putting nothing in /usr/include. The sdk then provides its
unique /usr/include above. However, the LLVM latest (which gives openmp), does
not know
that, and so it has to be told which /usr/include to use.
One can install command-line tools, but then one cannot have several sdk's
co-exist.
-fPIC: duplicative given --with-pic, but no harm, passed to all our packages.
-pipe: supposedly build performance, but I have not tested.
I *think* -DSTDC_HEADERS is a hint to Apple (but not to openmpi) to use only
headers
consistent with stdc.
Can you send all the information listed here:
https://www.open-mpi.org/community/help/
I have the following builds/build attempts:
3.3.4:
1. Not adding -DOPAL_STDC_HEADERS: build fails.
2. Adding -DOPAL_STDC_HEADERS: build succeeds, hdf5 parallel build fails.
3. Not adding -DOPAL_STDC_HEADERS, but setting CPPFLAGS to be identical
to CFLAGS:
openmpi and hdf5-parallel builds both succeed.
4.0.1, best formula above (CPPFLAGS set to same as CFLAGS):
4. Fails to build for a different reason.
Which would you like?
Best......John
