If you have compilation problems, please always state what version of CPMD you are trying to compile and what kind of machine you are using, i.e. what operating system, what compiler (particularly important on linux machines), which compilation flags, and what libraries you are using. Best you include the first part of your makehttp (up to `End of Personal Configuration', please don't post the whole makehttp) as this contains most of the required information. Also include the relevant part of the make output (again, the full output usually is very long and rarely needed).
If you have problems with a specific calculation, please include your input and the output of the run, so that others can try to reproduce the error. Again, please state the version of CPMD you are using and the platform you are running on.
