Hello,
I'm in the process of upgrading our HDF5 sources from 1.8.5 to 1.8.8
(both built with CMake). It worked flawlessly on Linux, but I've
encountered an oddity on Windows, where we use MSVC along with Intel's
Fortran compiler. Linkinh an application causes the linker to
complain about the symbol _gettimeofday missing in function
_HDFP_log_open. This isn't surprising, since gettimeofday is a POSIX
function and to my knowledge isn't provided by the runtime libs coming
with MSVC.
Checking the code in H5FDlog.c showed that the H5_HAVE_GETTIMEOFDAY
preprocessor symbol must be related. Searching for this string in the
hdf-1.8.5 and 1.8.8 directories lead me to the following in
release_docs/HISTORY-1_8.txt in hdf5-1.8.8
Bug Fixes since HDF5-1.8.6
==========================
- Fixed the definition of H5_HAVE_GETTIMEOFDAY on Windows so that
HDgettimeofday() is defined and works properly. Bug HDFFV-5931
(DER - 2011/04/14)
This is change is done for CMake in config/cmake/ConfigureChecks.cmake:
IF (WINDOWS)
..
SET (H5_HAVE_GETTIMEOFDAY 1)
..
ENDIF (WINDOWS)
und for VisualStudio in windows/src/H5pubconf.h
#define H5_HAVE_GETTIMEOFDAY 1
though I haven't tried to built using the VisualStudio files.
I'm not sure what's the right thing to do for me here. Can I just
comment out the SET (H5_HAVE_GETTIMEOFDAY 1) ? Or am I supposed to
link in a 3rd party library which provides the gettimeofday?
Best Regards,
Maik Beckmann
