Anyway, I assume too much. Is this an FBtoC compile? Brian General note for all posters when requesting help. Please include the following information. It is always helpful: (1) Which version of FB are you using ( either FB 4.4.3 or FB 5 ) ? and are you using FBtoC to compile (2) Which OS release ? (3) Which flavor of Mac? ( i.e. most important is Intel Mac or PowerPC Mac )
