I have recently updated OWLNext to v7.0.7 and I am now getting the the following linker error: Error: Unresolved external 'owl::__OwlDiagGroupDef' referenced from C:\SOFTWARE DEVELOPMENT X.7\CB11.0 ALEXANDRIA\WIN32\OBJ\DEBUG\REWARD2.EXE\EARTHPRESSURES2.OBJ I have looked in the referenced file 'EarthPressures2.cpp' (and its header) but can find no mention of OwlDiagGroupDef or anything that refers to it (like the macro CHECK). Can anyone suhgest how I could be triggering this error and - better still...

Vidar Thanks for your reply, that has solved my problem. And thanks also for the advance warning about this feature's removal from OwlNext 8. Andrew

I have recently updated OWLNext to v7.0.7 and I am now geeting the the following linker error when I attempt to link to the static lib file owl-7.0-c760-x86-dtu.lib (generated by OwlMaker): Unresolved external 'owl::TFileDocument::TFileDocument(owl::StreamableInit)' referenced from ... GCXDOC.OBJ Do I have to set some flag in order for OwlMaker to provide the mssing external? Thaksin advance to anyone who can tell me how to overcome this error. Andrew

Vidar Thanks for the welcome and timely response. I created my own cbproj file to create the OWL dll, adding the files and settings listed in the OWLNext-generated make file to populate the project. Everything worked just fine once I defined a few macros - such as and the onethat enables persistent streaming and, of course, _BUILDOWLDLL . I use streamable objects throughout my app (which was originally reated way back in 1992, using the original OWL library and Borland C++ 5 - not C++Builder!). This...

I am porting my OWLNext app to OLWNext 7.0.7. Using C++Builder 10.4.2 Sydney, CLANG compiler, 32-bit. I have always used dynamic linking to avoid code bloat (since I have a lot of DLLs in supporting my app). I have therefore built the owl dll (owl-7.0-c750-x86-dtui.dll) and successfully linked it to my DLL. But ... I am only able to do that if I turn persistent object streaming off. With streaming on, I get two unresolved externals at link time, as follows: [Linker Error] Error: Unresolved external...
