On MacOS X 10.8 (where cc and c++ are clang and clang++, and the default
ABI is LP64) I've configured the release candidate with
--prefix=.... --enable-debug CC=cc CXX=c++
The build fails linking opal_wrapper as shown in the "make V=1" output
below.
Based on the undefined symbol (_lt_libltdlc_LTX_preloaded_symbols) I am
guessing this is a libltdl issue. If relevant, note that configure picks
the embedded libltdl:
*** GNU libltdl setup
checking location of libltdl... internal copy
configure: OMPI configuring in opal/libltdl
Oddly enough, I have no problems with a build configured for the ILP32 ABI
as follows:
--prefix=.... --enable-debug CC=cc CXX=c++ \
CFLAGS=-m32 --with-wrapper-cflags=-m32 \
CXXFLAGS=-m32 --with-wrapper-cxxflags=-m32 \
FCFLAGS=-m32 --with-wrapper-fcflags=-m32
I can send (off-list) the config.log and configure's complete stdout for
both the LP64 and ILP32 builds if requested.
