RE: [Axiom-developer] Running Axiom in Texmacs for Windows (was:[Texmacs-dev] Plugins)

[Mike Thomas]

Hi Bill/Dan.

I've attached some code which shows how to launch a subprocess with
redirected stdin/out on Windows, which you might like to incorporate into
tm_axiom.c.  I haven't run it for a couple of years but I recall that it
worked when last I tried!

The _spawn family of functions on Windows does almost exactly what fork/exec
does on Unix; you also have _dup2, _pipe etc.  The examples switchable by
macro to use the pure Win32 functions CreateProcess etc and also to redirect
stderr; I made these programs as a learning exercise at the time.  The
threading in this code is, I expect, not relevant to tm_axiom.c and can
safely be disregarded.

You can find the MSDN docs on these functions by googling for "msdn
_spawnvp" etc.

Best of luck,

Mike Thomas

| Dan,
|
| I know this would not be considered a final solution, but
| I have found a way to work around the problems of compiling
| tm_axiom.c under windows. tm_axiom.c uses the unix-isms fork
| and pipe which are not available under vanilla windows so
| tm_axiom.c would have to be seriously re-written in order
| to run under native Windows.
|
| But I found that if I copied tm_axiom.exe from the cygwin
| distribution of texmacs (which I also happen to have on
| this system)
|
|   C:\cygwin\usr\sbin\TeXmacs\bin\tm_axiom.exe
|
| and the cygwin library
|
|   C:\cygwin\bin\cygwin1.dll library
|
| into
|
|   C:\Program Files\WinTeXmacs\TeXmacs\bin
|
| then the new version of Axiom for Windows works with Texmacs
| for Windows! Of course cygwin is providing the fork and pipe
| emulation that is needed for the unix version of tm_axiom.
|
| In principle, tm_axiom.c is a fairly simple filter program.
| Perhaps you or someone on the texmacs-dev list could point
| me to a simple example of a native Windows program that does
| the same thing? I could try to produce a new version of
| tm_axiom.c for the windows distribution.
|
| Regards,
| Bill Page.
