DDE library

Hi,all Recently, i wrote a simple sound server that only contains DDE initialization routines and tried to compile it with DDE libraries. After checking the Makefile in dde/linux26/lib/src, I guess i need the library 'libdde_linux26_sound.a' to link with, but it seems that i need to write the source code 'sound.c' to map linux functions to DDEKit. How can i implement this? any suggestion or hint? Thank you in advance Saya
