Hi, I finally reproduced an unjust "`somfile.gpi' must be recompiled" message with a minimal example. This is the tree: \ywin.pas \testy.pas \contrib\gpc.o \contrib\gpc.gpi gpc.* are compiled from gps.pas as supplied with the compiler. ywin.pas and testy.pas are as follows ============== ywin.pas START =================== MODULE ywin; EXPORT ywin = (dummy); IMPORT gpc only (PCStrings, CParamCount, CParameters); procedure dummy; end; procedure dummy; begin end; { dummy } end. ============= ywin.pas END ===================== ============= testy.pas START ==================== program testy; import ywin; begin end. ============= testy.pas END ====================== ============ Compile log START ================

gpc -c -g --unit-path=contrib ywin.pas

gpc testy.pas testy4.pas:3: `ywin.gpi' must be recompiled

============= Compile log END =================== If ywin.pas and testy.pas live in the same directory you can get around this problem by making testy.pas with --automake, but if they live in different directories that does not work. The problem goes away if gpc.* are put together with ywin.pas. I have not tested whether this is a particular problem of gpc.pas or whether it happens with any unit interface. Best regards, Bastiaan.
