Hi Junting,
I have succeeded to use the latest pyfr and CGNS3.4.0 to import both
yf17.cgns.gz <http://cgns.github.io/CGNSFiles/Bruce/yf17_hdf5.cgns.gz> and
yf17_hdf5.cgns.gz <http://cgns.github.io/CGNSFiles/Bruce/yf17_hdf5.cgns.gz>.
So, I would recommend to build and install from the source using cmake:
$ git clone https://github.com/CGNS/CGNS.git
$ cd CGNS
$ mkdir build
$ cd build
$ cmake ..
$ ccmake .
Then, followings are what I set. I have once experienced enabling 64bit
caused error in CGNS3.3.0, so I have turned it off (but not sure if it's ok
now).
CGNS_BUILD_CGNSTOOLS ON
CGNS_BUILD_SHARED ON
CGNS_BUILD_TESTING OFF
CGNS_ENABLE_64BIT OFF
CGNS_ENABLE_BASE_SCOPE OFF
CGNS_ENABLE_FORTRAN OFF
CGNS_ENABLE_HDF5 ON
CGNS_ENABLE_LEGACY OFF
CGNS_ENABLE_MEM_DEBUG OFF
CGNS_ENABLE_SCOPING OFF
CGNS_ENABLE_TESTS OFF
CGNS_USE_SHARED ON
CMAKE_BUILD_TYPE Release
CMAKE_INSTALL_PREFIX /data/home/yoshiaki/local/CGNS/build
HDF5_C_LIBRARY_dl /usr/lib64/libdl.so
HDF5_C_LIBRARY_hdf5 /usr/lib64/libhdf5.so
HDF5_C_LIBRARY_m /usr/lib64/libm.so
HDF5_C_LIBRARY_sz /usr/lib64/libsz.so
HDF5_C_LIBRARY_z /usr/lib64/libz.so
HDF5_NEED_MPI OFF
HDF5_NEED_SZIP OFF
HDF5_NEED_ZLIB OFF
Then, export LD_LIBRARY_PATH=the path to libcgns.so, and install pyfr.
Note that it is also important to appropriately link HDF5 library in
libcgns.so, which is discussed in the following thread:

I hope it helps you.
Regards,
Yoshiaki
