Creating a LIB or DLL

[Antonio Linares]

Dave,

Please build FWH\samples\tutor01.prg and check if you get the first MessageBox() from hb_vmInit()

FWH\samples\buildh.bat tutor01

Here it shows fine.

Antonio,

I created a new folder called HS2 and did my checkout in to it.

I copied over my makeb32.bat, make_b32.bat, make_b32.mak. and common.mak

My makeb32.bat

Code: Select all  Expand view

    del \harbour\bin\*.exe

Dave,

I think I have found where the exception is coming from. It is a Harbour bug.

Please make this change in harbour\source\vm\hvm.c function hb_vmInit():

Code: Select all  Expand view

   if( bStartMainProc )   // new !!!
      hb_cmdargUpdate();
 

Now there is no exception though the DLL function is not working yet. I keep doing tests.

[Antonio Linares]

Dave,

Please use this makeb32.bat:

Code: Select all  Expand view

@ ECHO OFF
SET PATH=c:\bcc55\bin;c:\mingw\bin;%PATH%
SET HB_COMPILER=bcc
SET HB_USER_CFLAGS=-DHB_FM_STATISTICS_OFF
make_gnu clean install > make_gnu.log 2>&1
 

It is the one that Enrico provided to us and it works fine

[Antonio Linares]

The Harbour bug comes from here:

In harbour\source\vm\cmdarg.c function hb_cmdargUpdate() s_argv[ 0 ] is used:
s_argv[ 0 ] = s_szAppName;
but it is not initialized for a DLL.

We are going to report it to the Harbour devel mailing list.

[Antonio Linares]

Dave,

The DLL is properly working (once the bug fix that I described is applied). I just missed to use __export in maindll.c

LONG PASCAL __export HBDLLENTRY2( char * cProcName, LONG pItem1, LONG pItem2 )

Here you have the DLL to test it (using FWH\samples\babu.prg):
http://www.mediafire.com/?sharekey=d045 ... eaa7bc68bc

[Dave Zowasky]

Antonio,

I downloaded the DLL and it works perfect.

I applied the code you described to

my \hs1\harbour\source\vm\hvm.c

Code: Select all  Expand view

  {
      HB_STACK_TLS_PRELOAD
      s_main_thread = hb_stackId();
      /* _SET_* initialization */
      hb_setInitialize( hb_stackSetStruct() );
   }
 if( bStartMainProc )
   hb_cmdargUpdate();

   hb_clsInit();              /* initialize Classy/OO system */
   hb_errInit();

   /* initialize dynamic symbol for evaluating codeblocks */
   hb_symEval.pDynSym = hb_dynsymGetCase( hb_symEval.szName );

   hb_conInit();

I am using my makegnu.bat and it looks like it compiles fine however I am still getting exception.

Any possibility of getting a copy of the harbour.exe that you used to compile the babudll?

Thanks

[Antonio Linares]

Dave,

> Any possibility of getting a copy of the harbour.exe that you used to compile the babudll?

Here you have it
http://www.mediafire.com/?sharekey=414c ... 0a1ae8665a

[Dave Zowasky]

Antonio,

I downloaded tried with new harbour.exe and same problem

here is mine from last create.

Just exe:
http://com1software.com/products/professional/harbour

This file contains:
BABU.EXE
BABU.PRG
BABUDLL.DLL
BABUDLL.PRG
BUILDHD.BAT
HARBOUR.EXE
MAINDLL.C

http://com1software.com/products/profes ... arbdll.zip

I will be running some more tests

Thanks

[Antonio Linares]

Dave,

Please check that you are using the Harbour that I have provided you and not another one

[Dave Zowasky]

Antonio,

Yes, I have made very sure to get the correct harbor installed.

I have been looking close at the maindll.c

Dave,

Everything seems ok. In maindll.c I just exported HBDLLENTRY2 and it was enough.

If you build babu.exe, are you able to manage my babudll.dll ?

[Antonio Linares]

Dave,

Don't use -DHB_DYNLIB here:

%bcdir%\bin\bcc32 -c -DHB_DYNLIB -I%hdir%\include;%bcdir%\include -L%bcdir%\..\lib maindll.c

[Dave Zowasky]

Antonio,

Yes, babu.exe manages your babudll.dll very good.

Don't use -DHB_DYNLIB here:

%bcdir%\bin\bcc32 -c -DHB_DYNLIB -I%hdir%\include;%bcdir%\include -L%bcdir%\..\lib maindll.c

What should this line look like?


Thanks
