Hello, Currently I’m working with OpenFOAM 20v06 and I am installing the Precice-adapter package just to have some errors. I have uploaded the log\_error txt file having the message error. With this error, I can assess the quickstart tutorial. Please how can I solve such issue?[Log\_Error.txt](https://precice.discourse.group/uploads/short-url/hdGCMU3z4LO63uDXB1tqlGFAgUi.txt) (31.1 KB) ---

Hi Axel, I understand from the log file that you have issues with the Qiuckstart tutorial when trying to build the rigit body solver. First error: ``` [50%] Linking CXX executable rigid_body_solver /usr/bin/ld: warning: libboost_filesystem.so.1.71.0, needed by /usr/lib/x86_64-linux-gnu/libprecice.so.2.2.0, not found (try using -rpath or -rpath-link) ``` Did you build preCICE from source? How did you install Boost? It is probably that Boost is not discoverable in your system (e.g. it is not in the `LD_LIBRARY_PATH`: [Building from source - Dependencies | preCICE - The Coupling Library](https://precice.org/installation-source-dependencies.html#build-boost-from-source)). ---

Hi Makish, I realized that I did not install Boost. I just successfully installed Boost. I guess. But when I opened a new terminal, I have this message error : bash: /home/user/.bashrc: line 126: syntax error near unexpected token `newline' bash: /home/user/.bashrc: line 126: `export BOOST\_ROOT=’ You can more details in the image. ![Screenshot from 2021-05-01 11-01-46](https://global.discourse-cdn.com/free1/uploads/precice/original/1X/4b88661ed582227e0cbf0bb46ee15525bbe82a84.png) Please help. The error is persisting I and can’t run the quick start tutorial. Best regards, Axel ---

How did you install boost? It seems like you have edited the `.bashrc` file in your home directory. Open it go to line 126 and fix it. It seems that you want to set `BOOST_ROOT` to some meaningful value (in this case a meaningful path). It seems that it is set to `` which is not meaningful. It should be something like `export BOOST_ROOT=/home/user/boost-1.72.0/` (just an example). If you have installed Boost via the package manager of your Linux, you normally do not have to set `BOOST_ROOT` manually. In this case you should remove the problematic line from your `.bashrc`. ---

Hi again Makish, I just built from source the dependencies Boost, Eigen, PetSc, etc… untill now, this is the error I am still receiving in the logfile. What could be the source of this error? ---

Hi Ajaust, I have followed the steps given on the website : [Building from source - Dependencies | preCICE - The Coupling Library](https://precice.org/installation-source-dependencies.html#petsc), point 5 (under Build boost from source). I have removed the line export BOOST\_ROOT= and that message error disappear from the terminal. However, when running the Quickstart tut, still having some errors as shown in the error\_log file attached. [error2.txt](https://precice.discourse.group/uploads/short-url/9ezlU7HtvgydKxE8RZoHZBfdJgQ.txt) (31.1 KB) Please what could caused this? Best regards, Axel ---

Hi, if you have followed the guide and installed Boost from source, you will need the line ` export BOOST_ROOT=` in your `.bashrc`. However, you have to replace the `` part by the system path to your Boost installation. This means, you need to put the path in that you have also used when installing boost using the command ``` ./bootstrap.sh --with-libraries=log,thread,system,filesystem,program_options,test --prefix= ``` Which Linux are you using? It might be easier for you to use the precompiled preCICE package and the precompiled dependencies. ---
