Compiling a root application with MS VC6

ROOT
1

Hi,

I am trying to compile hello.cxx using MS VC6.
I succeeded to make a project file and the workspace,
and even I can compile and link the project. There is,
however, one error message I cannot rid off:

Linking…
LIBCD.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
Debug/Hello.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

I guess that the main() is missing (in the console version) or
(WinMain in the windows version). What is the trick to build the app?
Is there a makefile around?

BTW: I also tried the following, with no success.
Do I wrong something?

Regards
Janos

C:\root\test>nmake -f makefile.win32

Hi Janos,
you didn’t say anything about your ROOT version.
Everything works OK with ROOT supported version
WindowsXP/NT/w2000 with VC++ 7.1 (runs with VC++6), version 4.01/04 (good old tar file) WIN32GDK

Just run “make” in test directory.

Hi Valeri,

this is the ROOT login:

  • Version 4.00/08 9 July 2004 *
    Compiled for win32.
    CINT/ROOT C/C++ Interpreter version 5.15.138, May 23 2004

Concerning make:
I have a Borland compiler installed, that fires first:

F:\root\test>make
MAKE Version 5.2 Copyright © 1987, 2000 Borland
Error makefile 10: Command syntax error
Error makefile 18: Command syntax error
Error makefile 20: Command syntax error
Error makefile 22: Command syntax error
…

The funny business is that right now nothing is found,
although the file is there:
root [0] .x hsimple
Error in TRint::ProcessFile: macro hsimple not found in path .;f:/root/macros
root [1] .x hsimple.h
srror in TRint::ProcessFile: macro hsimple.h not found in path .;f:/root/macro
root [2] .x mydemo.h
Error in TRint::ProcessFile: macro mydemo.h not found in path .;f:/root/macros
root [3] .q

This is the end of ROOT – Goodbye

Hi Janos,

  1. as I mentioned “win32” is not supported version
  2. root [0] .x hsimple.C //not .x hsimple
  3. you need to use MS VC (>= 6.0) compiler. Not Borland.

Hi Valery,

In case of MS VC, I think I need nmake (rather than make)
This alone, results in

F:\root\test>nmake

Microsoft ® Program Maintenance Utility Version 6.00.8168.0
Copyright © Microsoft Corp 1988-1998. All rights reserved.

Makefile.arch(8) : fatal error U1033: syntax error : ‘=’ unexpected
Stop.

With the correct usage (I guess)
F:\root\test>nmake -f makefile.win32

Microsoft ® Program Maintenance Utility Version 6.00.8168.0
Copyright © Microsoft Corp 1988-1998. All rights reserved.

makefile.win32(7) : fatal error U1052: file ‘win32.mak’ not found
Stop.

And really, that file is missing from the distribution.
Could you please help me how to find it?

Thanks

Janos

Hi Janos, ooops …
da, really, two choises here

  1. nmake -f Makefile.win32
    but this makefile doesn’t compile many of the programs, e.g.
    guitest, guiviewer etc

  2. run cygwin’s make for $ROOTSYS/test/Makefile.
    It uses MS VC compiler, linker

  3. … or create VC project. VC7.1 projects for $ROOTSYS/test
    programs are in attachment.

Hi Valery,

this would be optimal for me. Could you please send these project files
in VC6 format (or the corresponding makefile)? Thanks in advance.

Regards,
Janos

Hi Janos,
I just searched my computer … seems I lost
my VC6 projects files for $ROOTSYS/test. I’ll check it
in another place. Meanwhile you can use
$ROOTSYS/test/Makefile.win32 which works with VC6
although compilation of some programs is missing.

Hi Valery,

I would, but the file ‘win32.mak’ is missing from the distribution.

Hi Janos,
win32.mak is in C:\Program Files\Microsoft Visual Studio\VC98\Include

To compile $ROOTSYS/test programs you should first to
"tune" VC inviroment by execution of
C:\Program Files\Microsoft Visual Studio\VC98\Bin\vcvars32.bat
