In the ros3 VFD, passing an empty string parameter to an internal
API call could result in accessing the -1th element of a string.
This would cause failures on big-endian systems like s390x.
This parameter is now checked before writing to the string.
Fixes GitHub #1168
* Fix printf warnings in t_mpi
The type of MPI_Offset varies with implementation. In MPICH, it's long,
which raises warnings when we attempt to use long long format
specifiers. Casting to long long fixes the warnings.
MPICH defines MPI_STATUSES_IGNORE (a pointer) to 1, which raises warnings
w/ gcc. This is a known issue that the MPICH devs are not going to fix.
See here:
https://github.com/pmodels/mpich/issues/5687
This fix suppresses those issues w/ gcc
This macro was an attempt to quiet warnings about release mode unused
variables that only appear in asserts. It resolves to a void cast, which
doesn't quiet warnings when an assignment has already taken place.
A strncpy call in a path construction call used the size of the src
buffer instead of the dest buffer as the limit n.
This was switched to use the dest size and properly terminate the
string if truncation occurs.
* Adds a config/clang-fflags options file to support Flang
* Corrects missing "-Wl," from linker options in the libtool wrappers
when using Flang, the MPI Fortran compiler wrappers, and building
the shared library. This would often result in unrecognized options
like -soname.
* Enable -nomp w/ Flang to avoid linking to the OpenMPI library.
CMake can build the parallel, shared library w/ Fortran using AOCC
and Flang, so no changes were needed for that build system.
Fixes GitHub issues #3439, #1588, #366, #280
The thread-safety feature on Windows requires a hook in DllMain() and
thus is only available when HDF5 is built as a shared library.
This was previously a warning, but has now been elevated to a fatal
error that cannot be overridden with ALLOW_UNSUPPORTED.
Fixes GitHub #3613
