I can't get ZipBuilder to compile/install using CBuilder 4 & ZipBuilder 1.78.1.2. It fails on line 2072: void __fastcall TZipWorker::DllCallBack(CallBack::PZCallBackStruct cbr) { .... 2070: if(OnMessage) OnMessage(Builder, GE_Unknown, "Skipped " + 2071: ExtMsg(CMsg, cbr, XIdent, XPreamble) 2072: + " " + IntToStr((cbr->FileSize & 0xFF) -1)); ... } It shows error: ZipWrkr.cpp(2072): E2015 Ambiguity between '_fastcall Sysutils::IntToStr(_int64)' and '_fastcall Sysutils::IntToStr(int)'. It compiled and installed with CBuilder 5 without any problems. I deleted all of the .obj files before trying to compile with CBuilder 4. Any ideas?
