Cool. Thanks a lot! > Now it seems it still wants to install (non > existing) HDF5 files. I guess this is a relict of the local copy of hdf5 files and it just needs fixing the install target. Hmmm, may be I'll manage tomorrow (if nobody beats me before ;-) ). Thanks a lot for your help Andreas. -- http://fam-tille.de

In summary, Debian flags set -Wformat and -Werror=format-security, but the package also sets -Wno-format which overrides the former and results in the error message. Pushed another patch. Now it seems it still wants to install (non existing) HDF5 files. best, Gert

Now I understand: My changeroot is sid, but the host machine runs on testing, so I didn't get the latest compiler version. The culprit now is that with g+++ 7.2.0 one can give -Werror=format-security without setting also -Wformat, as of g++ 7.2.1 this is now an error, and one needs both, -Wformat and -Werror=format-security, hence the error. Best, Gert
