Hi Alexander,

> Do you develop direct bindings of wxWindows to OCaml, or develop the 
application layer you need directly in VC++ and call it from OCaml?

If I had some experience with developing direct bindings the way they did with 
WxPython (for example), I might attempt to do something similar with OCaml.  I 
am not very happy with Tcl/Tk and I couldn't even get that working with OCaml 
anyway.

I have a more modest solution, however: to write the whole front end in VC++ 
using wxWindows, and call my OCaml code from that front end.  I am not 
especially interested in handling GUI events from OCaml anyway.  But if it were 
not too hard to create something like a wxOCaml, I would use it for sure.  Of 
course, one hurdle would be to get the interface to C/C++ working, which is 
what camlidl seems to be good for.

Ok, at least the word is pronounced. Indeed, wxPython is the most advanced set of
third language bindings to wxWindows, and may be used at least as a reference.

A slight clarification to my earlier post...

I am using the native Win32 port of OCaml, not Cygwin.  I plan to work in the 
native Win32 environment (since I don't have a Linux box), and I am using the 
wxWindows library with Visual C++ for GUI front-end coding.

Since camlidl is at least in part a Windows-oriented utility, my expectation 
was that I would not have to make it from a bash console.  I simply don't have 
much experience with bash.  Any pointers?

Thanks,

Kyle Pierce

Do you develop direct bindings of wxWindows to OCaml, or develop the application
layer you need directly in VC++ and call it from OCaml?

Just my $0.02:

camlidl let you call C functions from caml, automatically generating all
necessary interface code (main caml program, C library). It also supports
COM ABI under Win32/Unix -- you can have main C/C++ program (or any other
COM-compatible application), and call caml component for any service.

Rigth now I am trying to use caml for some part of large Win32 project,
most of which is being developing using MSVC. Camlidl does its job,
although some non-fixed bugs are still there.

Hope to hear from you soon,
Dmitry

Only working GNU "make" is necessary, if you do not plan to build
ocaml COM objects, packed as DLL. In the latter case you will also need
"bash" to run camlidldll script. Both "make" and "bash" are available as a
part of free Cygwin environment (http://sources.redhat.com/cygwin). If you
only need GNU make, you can forget about Cygwin and grab native Win32 GNU
make from
ftp://ftp.nanotech.wisc.edu/pub/khan/gnu-win32/mingw32/ports/make-3.77-mingw32.zip

Absolutely no problem bulding camlidl in the very similar environment
(WinNT 4.0 instead Win2000). Be sure that "make" is in you path and follow
readme instructions.

[Caml-list] Making camlidl

[kyle.pierce]

Hello,

One of my first experiments with OCaml has been to try and build the camlidl 
utility (version 1.01) to help me build a library with OCaml and then call it 
from a C++ executable.  I'm in a Windows 2000 environment, but no COM features 
are needed, I just want the glue code for integrating with C/C++.

However, I am having a terrible time getting camlidl built.  I have GNU make 
and the cygwin utilities installed, as suggested in the readme file.  I cannot 
get beyond the various problems I'm having with this.  Would I have to actually 
do the build entirely within the cygwin environment, using bash?  Or what?  I 
would be grateful for any suggestions.

Alternatively, has anyone built a native code camlidl.exe that you would be 
willing to share?  Or for that matter, a bytecode version?

Thanks,

Kyle Pierce
