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 Dana,

Thanks for your response.

 

I've tried with your method to patch and compile hdf5-1.10.0-patch1 source 
code. Patch and compile have no error. Unfortunately when run my code the error 
still exist. And error information is the same as before.

 

What should I do? Please help me.

 

Thank you again for your effort!

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.

 

Cheers,

Hi, 

I have met an obscure failure, and not find a good solution for two days. Could
