Clarifications regarding BDM GDB Insight for M68k

[Prasanna - Khanapur]

Hello,
I'm trying to make Insight GDB BDM for M68k processor in cygwin 
environment on an WINNT machine.
I installed the latest cygwin version on the WINNT and 
uncomopressed the insight-5.0.tar.bz2 file on the cygwin dir.
I ran the configure and make file :

>./configure --target=m68k-bdm-elf
>make

I faced few problems for which I made some fixes, some header 
files where not included so included the corresponding the files 
needed.

But at the end that is in the final linking of the gdb.exe I had 
faced the following errors:

*********************************************************************************************************

After analysing the above errors in the function 'gdbtk_init' I 
found that _WIN32 is not  defined in the compilation
of some files like tclmsgbox.c ,tclsizebox.c etc..
Do I need to give any other parameter for the while running the 
./confiure file such that this _WIN32 is added on to the makefiles 
directly?

To solve the problem I defined -D_WIN32 as one of the  compiler 
options in the makefile.in.
After that I gave again compilation this time the follwing error 
is reported

I searched for this functions in the whole directory but could not  
find them.
If anybody can help out with few of above problems it would be 
help.
Please let me know whether whatever I have done is correct.

Insight-5.0 is not the latest version. Make sure you are trying to build
insight-5.1.

Your libgui problems should be fixed by using "-mwin32". There was a
change in gcc for cygwin between 5.0 and 5.1 which necessitates this flag.
I don't recall if the 5.1 branch sources have this in it or not, so it
might be needed there. (And don't include '-mwin32' everywhere -- just put
it where needed.)

Please verify which version of insight you are trying to build and get
back to us.

Doh! I completely overlooked this.. What happens when you use "-mwin32"
instbead of "-D_WIN32" (or in addition to)?

 As you can see the symbol name is not 'FreeConsole', but instead
'FreeConsole@0' !!!  So here should be your clue and asking why
the '@0' is there would give you a sane answer from anyone familiar
with the Cygwin or Mingw target...

 The answer is that the function prototype should declare this being
a 'WINAPI'-function :

    E:\usr\local\i386-mingw32msvc\sys-include>grep FreeConsole *.h
    wincon.h:BOOL WINAPI FreeConsole(void);

 The 'w32api'-headers (should be common for Cygwin and Mingw) should
declare this function as seen previously... So the 'gdbtk.c' doesn't
include the needed 'wincon.h' directly or via some other header, and
this causes the symbol name not being 'mangled' this way...

 I don't know whether '#include <windows.h>' should include <wincon.h>
too, or not, or what could be the 'right' fix... It can be to add the
'#include <wincon.h>' into some w32api-header which should now include
it, or to add this into the 'gdbtk.c' itself. But as an local workaround
the last choice could be the best...
