I tried to recompile MrEd with CodeWarrior 4.0 with the preprocessor symbol: #define STANDALONE_WITH_EMBEDDED_EXTENSION I get this error at the end: Link Error : undefined 'scheme_initialize' (code) Referenced from 'finish_cmd_line_run(FinishArgs*,void (*)(void))' in mred.cxx Is there a missing file in the source or what is wrong? Thanx
