There is something when I use cmake to configure dealii with hdf5

[cxmai...@gmail.com]

@davydden But after I finish configure the dealii:

sudo cmake -DCMAKE_INSTALL_PREFIX=/home/chenxi/DealIInew
-DDEAL_II_WITH_HDF5=ON
-DHDF5_LIBRARY=/usr/lib/x86_64-linux-gnu/hdf5/serial/lib
-DHDF5_INCLUDE_DIR=/usr/lib/x86_64-linux-gnu/hdf5/serial/include
 -DHDF5_HL_LIBRARY=/usr/include/hdf5/serial/hdf5_hl.h
-DHDF5_PUBCONF=/usr/include/hdf5/serial/H5pubconf.h ../.

(I follow https://www.coursera.org/learn/finite-element-method/discussions/all/threads/4CIlFMjHEeaFyhIY_gUU0g carefully)

But I still got some warnings:

But it works when I use make install to install dealii

What should I do to fix this problem?

Thank you very much in advance!!!!

It's generally a bad idea to do anything with 'sudo'. In your case, you
are installing into your home directory, so it is not even necessary here.

I don't know where they come from, but these are just warnings. You can
ignore them. As long as....

...it works, you should be fine. Can you run any of the tutorial programs?

Thank you! Professor W.

I have solved my problem, 

-DHDF5_LIBRARY=/usr/lib/x86_64-linux-gnu/hdf5/serial/lib 

this command should link a static library, not a /lib.
