IW 15.5.3 is out
Hi guys,

new update is available:

This update contains an important fix for the 15.5 branch.

Enjoy!  Big Grin
Hi Alexandre,

C++Builder 12
IW 15.5.3

I have the following error:

[ilink32 Fehler] Error: Nicht auflösbares externes '__fastcall Iwservercontrollerbase::TIWSSLOptions::SetPortW(const int)' referenziert von ...\WIN32\DEBUG\SERVERCONTROLLER.OBJ
[ilink32 Fehler] Error: Linken kann nicht ausgeführt werden

The class has probably been restructured compared to the previous version:

#pragma pack(push,4)
class PASCALIMPLEMENTATION TIWSSLOptions : public TIWServerControllerPersistentProperty
typedef TIWServerControllerPersistentProperty inherited;

System::UnicodeString FCertificatePassword;
int FPort;
TIWNonSSLRequest FNonSSLRequest;
TIWSSLVersion FVersion;
System::UnicodeString FCipherList;
System::UnicodeString FCipherSuites;
TIWSSLVersions FSSLVersions;
bool FEnableACME;
TIWSSLCertificateOptions* FCertificateOptions;
bool FSetOpenSSLPath;
void __fastcall SetCertificateOptions(TIWSSLCertificateOptions* const Value);
void __fastcall SetCertificatePassword(const System::UnicodeString Value);
void __fastcall SetDHParamsFile(const System::UnicodeString Value);
void __fastcall SetSetOpenSSLPath(const bool Value);
void __fastcall SetCipherList(const System::UnicodeString Value);
void __fastcall SetCipherSuites(const System::UnicodeString Value);
void __fastcall SetSSLVersions(const TIWSSLVersions Value);
void __fastcall SetEnableACME(const bool Value);
void __fastcall SetVersion(const TIWSSLVersion Value);
void __fastcall SetNonSSLRequest(const TIWNonSSLRequest Value);

void __fastcall SetPort(const int Value);

virtual void __fastcall Init();
__fastcall virtual ~TIWSSLOptions();
virtual void __fastcall Assign(System::Classes::TPersistent* ASource);

__property int Port = {read=FPort, write=SetPort, default=0};

__property TIWSSLCertificateOptions* Certificate = {read=FCertificateOptions, write=SetCertificateOptions};
__property bool SetOpenSSLPath = {read=FSetOpenSSLPath, write=SetSetOpenSSLPath, default=1};
/* TIWServerControllerPersistentProperty.Create */ inline __fastcall TIWSSLOptions(TIWServerControllerBase* AServerControllerBase) : TIWServerControllerPersistentProperty(AServerControllerBase) { }


Are you sure that you don't have any older version in your library path, in your C++Builder options?

This version was extensively tested in C++Builder 12 and no errors have been found.
I have installed C++Builder 12 only, all other directories, files and path entries has been removed.

The function belongs to the Microsoft SDK:

BOOL SetPort(
  _In_ LPTSTR pName,
  _In_ LPTSTR pPortName,
  _In_ DWORD  dwLevel,
  _In_ LPBYTE pPortInfo

Unicode- und ANSI-Name
SetPortW (Unicode) und SetPortA (ANSI)


The function is used by the following modules:


There was a similar problem before,
when wininet.lib/wininet.a failed in IWUtils.hpp (IW15.2.65),
That's why I tried to integrate the library myself:

#if _WIN64
#pragma message "Winspool.a"
#pragma link "Winspool.a"
#elif _WIN32
#pragma message "Winspool.lib"
#pragma link "Winspool.lib"

But it didn't work.

The Embarcadero header file winspool.h seems to be OK.
I have installed version Microsoft Windows 10 - SDK 21.0.

Is this the correct version ?
I also get this error with IW 15.5.3 / C++ Builder 11.3

The way to reproduce the error is to assign SSLOptions->Port in code, assigning in the IDE is works ok.
