Created attachment 584972 [details, diff] Fix HDF5 includes by forcing HDF5_INCLUDE_DIRS. Caution: also sets DETECT_HDF5, which is not strictly necessary for the problem at hand. When emerging with hdf5 support, use of armadillo will result in failed compiler calls with: fatal error: NOTFOUND/hdf5.h: No such file or directory It looks like HDF5 detection is broken. (Especially for the C-only component?) The armadillo ebuild is overwriting the corresponding HDF5 variables, i.e., -DHDF5_FOUND=ON and-DHDF5_LIBRARIES="-lhdf5". But HDF5_INCLUDE_DIRS is not set. Setting HDF5_INCLUDE_DIRS=/usr/include fixes this. Caution: The attached patch is also setting DETECT_HDF5, which is probably not necessary, but it seems a possibility to turn detection off completely, when not using HDF5.
