I am able to compile the example from doc/6.externs, I can also compile
iemlib but when I try maxlib, zexy or flext I keep getting errors - usually due to m_imp.h .
Hi Yasmin, do you have the m_imp.h file on your machine at all? It is likely that (when using PD from an installer package) you have only m_pd.h . In this case you should get the PD source from Miller's site ( http://crca.ucsd.edu/~msp/software ), and extract the m_imp.h . Put it into the location where m_pd.h sits... hopefully your compilation efforts are more successful then.
best greetings, Thomas
