Günther,

DLL FUNCTION ... is failing with FWH 64 BCC

We are working to fix it

Antonio, thanks!!! I am happy, not MY error.....
Best regards.

Günther,

Fixed

I have just emailed you the modified libs

many thanks for your feedback

Antonio, many thanks! Functioning now also in my projects!! What was the concrete reason for this error in dllcall ?

Günther,

Borland BCC 7 (7.1) has changed its "byte alignment" and now behaves like Visual C.

So in all places where byte alignment is used, we had to modify the code.

Antonio, there are different 64bit #defines: _WIN64 and 64. What is for what?

_WIN64 is automatically provided by the C compiler

We use 64 for the resources files only, as the resources compiler does not provide a similar _WIN64 define

Antonio, i found 64 also in fivewin.ch. Should in the FWH-header-files also used _WIN64 or is not visible at this moment of compilation!? FWVERSION gives wrong result, if 64 not defined!

A further point: The version from Harbour in FWH64 are newer as the Harbour from FWH. Should be all the newest!

And the libs for Harbour-BCC7.1 for FWH64 should compiled with -O2 to apply all compiler-optimizations.

Hi All,

which one is the best in 64 bit. Borland or msvc 2015?

in order to use 64 bit, must we have 64 bit for 3rd party libraries?

Thanks,

Hakan,

Yes

Thanks.

Francisco,

Please look for clui.dll in your computer and copy it where cl.exe is

Also check if you have these lines in your fwh\samples\build64.bat file:

if exist "%ProgramFiles%\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" call "%ProgramFiles%\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" x86_amd64
if exist "%ProgramFiles(x86)%\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" call "%ProgramFiles(x86)%\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" x86_amd64

Antonio,
