CHLone installation fails - hdf5

Question

I am trying to install CHLone v0.49 on Ubuntu 16.04 in order to install pyCGNS. The dependencies are installed and seem to be found by scons, as the beginning of the output shows when I run scons:
scons: Reading SConscript files ...
# =================================================================
# CHLone: production setup...
# CHLone: Cython & numpy found, add CGNS/Python build
# CHLone: Configuration uses HDF5 version 1.10.0-patch1 with:
# CHLone: + thread safe HDF5
# CHLone: + includes in ['/usr/local/hdf5/include']
# CHLone: + libraries in ['/usr/local/hdf5/lib']
# CHLone: compiler is gcc
# =================================================================
# CHLone: Build v0.49
# =================================================================
scons: done reading SConscript files.
However, it then runs into problems with an output like:
scons: done reading SConscript files.
scons: Building targets ...

Can anyone help me what to do? I have no clue what the problem might be...

Answer 1

I had the same problem and the answer is in fact in the compiler log. It says that the return type of function L3_incRef in l3.c (int) is not consistent with the one in the header l3.h (hid_t).
After changing the return type of L3_incRef into int in l3.C, the code compiles successfully.
