Hi! I tried installing FreeFem++ using both the binary installation and the compilation for Ubuntu but I was unsuccessful with both methods. I’m still an Ubuntu noob and even though there seem to already exist solutions to my problem (FreeFem++: error while loading shared libraries: libhdf5\_serial.so.100: cannot open shared object file: No such file or directory ) i can’t seem to get it working. Any help would be appreciated. ---

You could recompile without HDF5, by adding `--without-hdf5` to your `./configure` line. ---

> [@nanmevi](#): > > I tried installing FreeFem++ using both the binary installation and the compilation for Ubuntu but I was unsuccessful with both methods. I’m still an Ubuntu noob and even though there seem to already exist solutions to my problem Dear prj, I have install in my laptop Ubuntu release 19.10 and I try to use FreeFrem++ in order to solve a integral equation through the finite element method. I followed all the step in the installation guide but when I execute the command “francisco@frajaroco:~$ FreeFem++ MC-pred-in.edp” from my terminal to run the code and get the result, the next message appears “FreeFem++: error while loading shared libraries: libhdf5\_serial.so.100: cannot open shared object file: No such file or directory” Yesterday I found your suggestion to solve the problem but given my minimums knowlemen about Ubuntu, I would very much like more detailed instructions on how to solve the problem. Thank you very much in advance! ---

Did you install the .deb or compile FreeFEM yourself? ---

I install “FreeFEM\_4.6\_Ubuntu\_withPETSc\_amd64.deb” from your website. ---

I think your HDF5 library is too recent, we build the .deb on Ubuntu 18, so it would be best to remove the package and compile FreeFEM yourself using [this](https://github.com/FreeFem/FreeFem-sources#freefem) procedure. ---

Dear prj, I’m having problems when running “make check”. The test file shows the FAIL and XFAIL. I install it in ubuntu 18.04 and follow the instructions on this website ([http://www3.freefem.org/ff++/linux.php](http://www3.freefem.org/ff++/linux.php)). ---
