Yes, you’ll certainly have to resolve this issue with not being able to compile a minimal HDF5 program before compiling OpenMC. But that is obvious. This may help you out: > [@CMake Error(could not find HDF5)](https://openmc.discourse.group/t/cmake-error-could-not-find-hdf5/850): > > Hi all, I recompiled OpenMC today and met the following error. -- The C compiler identification is GNU 9.3.0 -- The CXX compiler identification is GNU 9.3.0 -- Check for working C compiler: /usr/bin/cc -- Check for working C compiler: /usr/bin/cc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Detecting C compile features -- Detecting C compile features - done -- Check for working CXX compiler: /usr/bin/c++ -- Check for working CXX compiler: /usr/bin/c++ --… IMO it’s better to just not use conda if you don’t have a need to install multiple versions of stuff to the same system, although that is **not** a commonly held sentiment. If you’re on macbook, I would brew install hdf5 and the other dependencies. If this continues to give you trouble, you may want to consider installing OpenMC using docker. --- _[View the full topic](https://openmc.discourse.group/t/error-with-hdf5-when-installing-into-anaconda-environment-from-source/1572)._
