Unable to run example 3, write serial as is

[s-sajid-ali]

Describe the bug Unable to run example 3 as is (apart from a change to location of file).

To Reproduce

sasyed@MAC-140753 ~/D/p/t/c/build> make -j2
Consolidate compiler generated dependencies of target example
[  0%] Built target copy-compile-commands
[ 50%] Building CXX object CMakeFiles/example.dir/example.cpp.o

make: *** [all] Error 2

Expected behavior Example compiles and runs.

Software Environment

• version of openPMD-api: [0.14.5]
• installed openPMD-api via: [spack]
• operating system: [macos-12]
• machine: [Laptop]
• version of HDF5: [1.12.2]
• version of ADIOS2: [2.8.3]
• name and version of MPI: [MPICH 4.0.3]

Additional context The example works if with the change

Datatype datatype = determineDatatype(shareRaw(global_data.data()));

i.e. adding a shareRaw call before determineDatatype.

Potential fix Perhaps the example needs to be corrected to add the shareRaw call?

will be fixed by 0.15 release.

This looks like you accidentally tried compiling the dev version of the example against the release version of the openPMD-api. We extended the determineDatatype() function templates and updated the examples accordingly.
