Installing preCICE
1

Hi!

I tried to install preCICE on Ubuntu 18.04, but faied with both cmake and Scons. My installation procedure followed the online instruction step by step without any changes. The information saved in CMakeError.log are shown below. Is there someone succeeding in the installation on Ubuntu 18.04? Could you please give me some tips? Thanks!

Hey there!

It seems that you are missing a pthreads library, which should be included with the installation of boost. Could you verify that you have a boost library installed? Alternatively just try to install it by

sudo apt-get install libboost-all-dev

Hope this helps!
