Hi,

the standard directory is under Unix / Linux /usr/lib, where you as regular user can't write or copy any files. Use --prefix=<some path> when configuring hdf5 and H5hut. <some path> should be a directory where you have the permission to write, e.g. $HOME/extlib/build. 

Afterwards you have to instruct the compiler to search the libraries at this position using 

--with-hdf5=$HOME/extlib. 

Before calling cmake to configure OPAL you have to execute 

export H5HUT_DIR=$HOME/extlib

and 

export HDF5_ROOT=$HOME/extlib

in your terminal (assuming that you use bash as shell, check with `echo $SHELL`). Preferably you also set the two commands to the .bashrc file in your home directory together with 

export LD_LIBRARY_PATH=$HOME/extlib/lib:$LD_LIBRARY_PATH 

Hope this helps

Christof

Dear Dou Guoliang, dear Opal Community,

My name is Sebastian, I'm a grad student from Mainz, Germany.

I have exactly the same problems with hdf5 and h5hut. The recipes didn't work for me either. I found no fix on my own yet.

I tried to build on Ubuntu Mate 18.04. If there is a better dis that works (besides RHEL7), I'd love to hear your suggestions!

Cheers,
Sebastian

Hi OPAL'ers,

I am a student from Institute of Modern Physics(IMP),Lanzhou, China. This month, my mentor have given me a task to learn your OPAL which can help us to simulate a cyclotron in the future. Actually, I just started learning Linux and programing language. so in the process of building and installing OPAL, I have some questions to ask you.

-At the beginning , I didn't how to starte. I found the manual 2.0.0 ,but I didn't get some installation details. Because Finally, I found the webpage of "Compiling OPAL"(https://gitlab.psi.ch/OPAL/src/wikis/For-Developers/Compile-OPAL). According to webpage of Compiling OPAL, I started to building and installing the OPAL. So, did I get right way to build and install the OPAL?

-According the webpage of "Compiling OPAL",I should setup required software by scratch. But the build-recipes didn't work. So, I install them one by one. While I am building the H5hut, it prompt errors: cannot compile and link a HDF5 program. I have installed HDF5 from webpage of HDF5 Group and the installation's process didn't prompt errors. I get no ideal to solve the problem. And I read the webpage of "Build and install H5hut" (https://gitlab.psi.ch/H5hut/src/wikis/Installation/Installation) carefully. I found "If your HDF5 installation is not installed in one of the standard directories, specify the installation prefix with --with-hdf5=HDF5_PREFIX ."in the third part "3.Configure". But I didn't understand  "the standard directories".

So, how to get required software? Is it right that I install them one by one? How to solve that problem during the building and installing H5hut?

-Actually, I am a undergraduate from Lanzhou University(LZU). So, I didn't get enough knowledge about programing language.

So, can you recommend me some courses or books to help me learn the OPAL better?

Thanks,

Dou Guoliang.
