This may work:

#pragma BEGINDUMP

#include <Windows.h>

extern "C" {
FILE * _iob[] = { stdin, stdout, stderr };

FILE * __iob_func( void )
{
return ( FILE * ) _iob;
}
}

#pragma ENDDUMP

This one ?

hbssl.lib(ssl.obj) : error LNK2019: unresolved external symbol ___iob_func referenced in function _app_stdin

This seems the right version:

#pragma BEGINDUMP

#include <Windows.h>

FILE * _iob[] = { stdin, stdout, stderr };

FILE * __iob_func( void )
{
return ( FILE * ) _iob;
}

#pragma ENDDUMP

Hakan,

Please try to add this code to your main PRG:

#pragma BEGINDUMP

#include <Windows.h>

FILE * __iob_func( void )
{
return { * stdin, * stdout, * stderr };
}

#pragma ENDDUMP

Tim,

These unresolved externals from which modules are called ?

__stdio_common_vfprintf
__acrt_iob_func

Antonio, First, I do have 2015 installed. Second, the build references Studio 2013, not 15. ( v12.0 not v14.0 ) Most important, it has two missing externals: __stdio_common_vfprintf __acrt_iob_func If I change build64.bat to use V14.0 I still get the same errors. Also, this does not resolve the miss...

OK ...

I still have 3 problems: UNDEFINED

__vaCopy in _hb_vsnprintf found in hbcommon.lib

__iob_func in hbssl.lib ( I don't think you rebuilt this one )

_except_handler4_ommon in MSVCRTD.lib though I told it not to link this file by default ... it still goes to it.

Tim

Antonio,

The article I read indicated we need to rebuild all libraries with VC 2015. That would include the Harbour and FWH libraries.
