Inside this package i have an exported function that looks as simple as this extern PACKAGE void __fastcall Prueba(); void __fastcall Prueba() { TQuery *q= new TQuery(NULL); //-- Crashes here, in the new delete q ; } If i compile it with mypackage.bpl included as a runtime package it crashes But if icompile statically ( without mypackage.bpl included as a runtime package) it all goes ok. Does anyone knows what could be the reason of this ? This would mean that i couldn't do TQuery's in runtime packages, that can't be possible. Am i missing something? I want the packge to be a runtime package because, the package is intended to contain functions common to several "exe", and i don't want to compile every "exe" statically with this package . This is, i want to make my "exes" modular I can't debug into VCL because as i read out there, because it's not possible to debug with runtime packages.

My exe was compiled with bdertl.bpl statically and my bpl was compiled it with the bdertl.bpl dinamically and this caused this error. So take care of which runtime packages you compile with your bpl and your exes. As a rule i will compile all my bpls and exes with at least, the common runtime packages as runtime packages in both.That is, if there exists an A.EXE with X.BPL as a runtime package then, those Y.BPL that A.EXE depends on, will be compiled with X.BPL as a runtime package(and viceversa). I hope this helps. raulmola ha escrito: Quote: By the way... the error reported by borland debugger is this : --------------------------- Debugger Exception Notification --------------------------- Project modinvoicProject10A.exe raised exception class EAccessViolation with message 'Access violation at address 406F1770 in module 'bdertl60.bpl'.
