Hi Dana and Prentice,
Thanks for your help.
My problem has been solved perfectly. I use the h5c++ compiler to
compile the code, and it works. Wonderful!
Maybe I linked to the error libraries when I linked mannually.
Thanks again for your help!

Hi all,
The source patch removes all references to flock() so this error
should not be occurring, regardless of the permissions. If you are
still seeing errors, I suspect that you are linking to a different
HDF5 library than the one you patched.
One thing I would try is, instead of using g++ directly, try using
the h5c++ compiler wrapper that should be located in the bin
directory of the HDF5 install. That will ensure that you are
linking to the correct libraries. When you use h5c++, you won't
need to include the -I, -L, and -l flags for HDF5 paths and
libraries since h5c++ sets that up for you.

I know this may sound like a stupid question, but I have to ask,
because I've learned never to assume things: Are you sure you have
write access where you're trying to create this file? Have you
confirmed this by going the directory where you are trying to
create the directory and doing 'touch test', which will create an
empty file named "test"?

Hi Dana and Prentice,
Thanks for your response.
I've tried with your method to repatch and recompile
hdf5-1.10.0-patch1 source code. And I also checked the three
files H5private.h, H5system.c and swmr.c. They were actually
changed after run patch. Unfortunately when run my code the
error still exist. And error information is the same as before.
I compile the hdf5 code as follows:
patch -p0 < file-lock-removal.diff
./configure --prefix=/home/duc001/3dtools/hdf5-1.10.0
--enable-cxx --with-zlib=/home/duc001/zlib-1.2.8/
make
make clean
make check
make install
make check-install
echo $PATH as follows:
/home/duc001/3dtools/hdf5-1.10.0/bin
I compile my code as follows:
g++ -c test.cpp
-I /home/duc001/3dtools/hdf5-1.10.0/include
-L /home/duc001/3dtools/hdf5-1.10.0/lib -lhdf5 -lhdf5_cpp
//no error
g++ -o testRun test.o
-I /home/duc001/3dtools/hdf5-1.10.0/include
-L /home/duc001/3dtools/hdf5-1.10.0/lib -lhdf5 -lhdf5_cpp
//no error
./testRun // with error
Are there any questions in the above operation?
Thanks again for your effort!

Haijun,
Did do a 'make clean' or (even better) 'make distclean'
before recompiling your code? Make is supposed to
determine that the source files are newer than the object
files and build all the object files that depend on those
source files and so on, but it's possible that the
dependency tree broke down somewhere.
I would recommend deleting your entire HDF5 source
directory, unzipping HDF again, applying the patch, and
the going through the configure and make process again.

Hi Haijun,
If you are still getting a flock error, I'd be
suspicious that you aren't linking to the patched HDF5
library. The source patch completely removes flock so
you shouldn't be seeing file locking errors.

Hi,
It looks like flock() is not implemented on your
filesystem, which is causing the create call to
fail. flock() file locking is used by the HDF5
1.10.0 to help enforce
single-writer/multiple-readers (SWMR) semantics,
but is not necessary for correct operation of the
library. A fix for this problem should be
available in HDF5 1.10.1, but in the meantime you
can apply a source patch found here:
https://www.hdfgroup.org/HDF5/release/obtainsrc5110.html#conf
under "Patch to Disable File Locking" at the
bottom of the page.
