Creating a LIB or DLL

[Dave Zowasky]

Enrico,

Thanks for the advice, I made sure the bcc32.cfg and ilink32.cfg were set up and it works great.

Thnaks again

[Dave Zowasky]

Antonio,

I copied the newly created harbor.exe's to my harbour folder and verified I have current results.

Thanks

[Antonio Linares]

Dave,

I understand that you mean that with the new created Harbour you keep having the exception, right ?

Have you rebuilt the DLL and the EXE with the new created Harbour ?

[Dave Zowasky]

Antonio,

Correct, I still have the exception.

I have not added any traces to the VMinit to look deeper.

Thanks

[Antonio Linares]

Dave,

Ok, now in Harbour\source\vm\hvm.c function hb_vmInit() please place some traces and rebuild Harbour again and rebuild the DLL and the EXE:

Code: Select all  Expand view  RUN

...

#include <windows.h>  // new !!!

void hb_vmInit( BOOL bStartMainProc )
{
   HB_TRACE(HB_TR_DEBUG, ("hb_vmInit()"));

   MessageBox( 0, "before hb_xinit()", "ok", 0 );   // New !!!
   hb_xinit();
   MessageBox( 0, "after hb_xinit()", "ok", 0 );   // New !!!

   MessageBox( 0, "before hb_vmSetExceptionHandler()", "ok", 0 );   // New !!!
   hb_vmSetExceptionHandler();
   MessageBox( 0, "after hb_vmSetExceptionHandler()", "ok", 0 );   // New !!!

   MessageBox( 0, "before hb_vmSymbolInit_RT()", "ok", 0 );   // New !!!
   hb_vmSymbolInit_RT();      /* initialize symbol table with runtime support functions */
   MessageBox( 0, "after hb_vmSymbolInit_RT()", "ok", 0 );   // New !!!

   MessageBox( 0, "before hb_stackInit()", "ok", 0 );   // New !!!
   hb_stackInit();                        /* initialize HVM stack */
   MessageBox( 0, "after hb_stackInit()", "ok", 0 );   // New !!!

   ...
 

and so on, so we can detect where the exception is coming from.

[Dave Zowasky]

Antonio,

I keep getting compile error

Error: Unresolved external '_MessageBox' referenced from C:\HS\HARBOUR\LIB\WIN\BCC\HBVM.LIB|hvm

also this is how the initstack is.

Code: Select all  Expand view  RUN

#if defined( HB_MT_VM )
   hb_threadInit();
   hb_vmStackInit( hb_threadStateNew() ); /* initialize HVM thread stack */
   s_pSymbolsMtx = hb_threadMutexCreate( FALSE );
#else
   hb_stackInit();                        /* initialize HVM stack */
#endif
 

Thanks

Dave,

> Error: Unresolved external '_MessageBox' referenced from C:\HS\HARBOUR\LIB\WIN\BCC\HBVM.LIB|hvm

Do you get that error when building your DLL ? Or when you rebuild Harbour ?

Have you included #include <windows.h> inside hvm.c as I shown you ?

> also this is how the initstack is.
> #if defined( HB_MT_VM )

That define is for multithreading and we are not going to use it for now, thats why you can place the trace in the #else section.

[Dave Zowasky]

Antonio,

Yes, I forgot the #include <windows.h> inside hvm.c
I put it in there and still having some sort of problems.

When I added the messages in the HVM I was still not hitting them

To be sure I started over fresh with no changes

I noticed this in my log

I am still creating a harbour.exe

Any ideas?

[Dave Zowasky]

Antonio,

I have copied .bat .mak and .sh files
from my \harbour-1.0.1\contrib folder to my c:\hs\harbour folder



My make_b32.bat

Code: Select all  Expand view  RUN

@echo off
rem
rem $Id: make_b32.bat 7995 2007-11-19 14:13:53Z vszakats $
rem

call mtpl_b32.bat %1 %2 %3 %4 %5 %6 %7 %8 %9

when I run my makeb32.bat I get

MAKE Version 5.2 Copyright (c) 1987, 2000 Borland
Fatal: Unable to open makefile

in my make_b32.log. Should I be passing it any parameters?

Thanks

[Antonio Linares]

Dave,

> I am still creating a harbour.exe

If you previously delete harbour.exe and all the Harbour LIBs, do they get built again ?

[Dave Zowasky]

Antonio,

Maybe some progress.

I copied files from \harboursource\harbour-1.0.1\

to my \hs\harbour folder

now when I run makeb32.bat I get:


MAKE Version 5.2 Copyright (c) 1987, 2000 Borland

No EXE's created

Thanks

[Antonio Linares]

Dave,

I just followed Enrico's instructions and Harbour EXEs and LIBs were properly built on first try:

1. I did a checkout on a clean directory as I explained you in this thread.

2. I created a makeb32.bat in the same path where make_gnu.bat is with these contents:

Code: Select all  Expand view  RUN

@ 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
 

3. I run makeb32.bat and got everything properly built

[Dave Zowasky]

Antonio,

I have separated my makegnu.bat from my other makeb32.bat in my hs folder and have
put it in my hs1 folder. It does build for me too. I am going to start over with makeb32.bat in a fresh
folder.


My current makegnu.bat

Code: Select all  Expand view  RUN

del \hs1\harbour\bin\*.exe
del \harbour\*.exe
SET PATH=c:\bcc55\bin
SET HB_COMPILER=bcc
SET HB_USER_CFLAGS=-DHB_FM_STATISTICS_OFF
make_gnu clean install > make_gnu.log 2>&1
copy \hs1\harbour\bin\*.exe \harbour\bin\
 

Here is what I have in the hvm.c file.

Code: Select all  Expand view  RUN

/* application entry point */

#include <windows.h>  // new !!!

void hb_vmInit( BOOL bStartMainProc )
{
   HB_TRACE(HB_TR_DEBUG, ("hb_vmInit()"));

   MessageBox( 0, "before hb_xinit()", "ok", 0 );   // New !!!
   hb_xinit();
   MessageBox( 0, "after hb_xinit()", "ok", 0 );   // New !!!
   
   hb_vmSetExceptionHandler();

   hb_vmSymbolInit_RT();      /* initialize symbol table with runtime

support functions */

#if defined( HB_MT_VM )
   hb_threadInit();
   hb_vmStackInit( hb_threadStateNew() ); /* initialize HVM thread stack

*/
   s_pSymbolsMtx = hb_threadMutexCreate( FALSE );
#else
   hb_stackInit();                        /* initialize HVM stack */
#endif
 

I see a lot of this in my make_gnu.log.

I cannot seem to hit the messagebox in the VMinit()

I still get the exception before I hit the new before vminit messagebox


Thanks

[Antonio Linares]

Dave,

But you said that you: "Made it to before VMinit"

Has that changed ?

What MessageBox prompt do you see before the exception ?

[Dave Zowasky]

Antonio,

I am able to get the before vminit in the maindll.c not the one before in the hvm.c

Thanks
