I get a linker error in Intraweb 15.2.65 with C++Builder 11.1

[ilink32 Fehler] Error: Nicht auflösbares externes 'InternetOpenW' referenziert von C:\ATOZED11\INTRAWEB 15\LIBD11W32\INTRAWEB_15_D11.LIB|IWUtils

Try adding this:

#pragma link "wininet.lib"

Thanks for the tip, but I'm not using this API.

Apparently the API library is now required by the intraweb library but probably not included.

Correct. If you add it you will be able to link without error, I had to do the same.

Yes, you're right, but it's not my construction site.

The intraweb library needs to work without my help.

I just upgraded from IW 15.2.64 to IW 15.2.65!

Isn't IntraWeb written in Delphi? Delphi links to external libraries very differently than C++ does. I would not expect this kind of error to come from a Delphi-written library, even if it is being used in C++Builder. This is the kind of error you would see when C++ code calls a DLL function but the C++ project doesn't link to the DLL, since C++ uses different stages for compiling and linking. Delphi doesn't work that way.

I think AToZed just needs to add something like below to IWUtils.pas to fix it up for C++ Builder:

{$IFDEF CPUX64}

(*$HPPEMIT '#pragma link "wininet.???"'*)

{$ELSE}

(*$HPPEMIT '#pragma link "wininet.lib"'*)

{$ENDIF}

Probably an oversight. Maybe also add a minimal C++ Builder project to FinalBuilder to detect errors like this.

Exactly (wininet.a)

Can you please tell me your C++ project linking options?

I believe MJS is right but not Delphi compiler (or unit test) nor C++ compiler (yes, maybe a unit test) can ever say me that.

The example contains a new, empty project.

As soon as linking is done without runtime packages, the error occurs.

Options->Packages->RuntimePackages: OFF
