make-regexp on mingw

make-regexp on mingw

[Richard Shann]

In porting GNU Denemo to windows I noticed that make-regexp is not
present. I found an obscure comment in one file that indicates this is a
known limitation. Can anyone confirm this? Are there some release notes
that I should have seen?
Is it a problem that is likely to be fixed?

FWIW, I work with another app (completely unrelated
to guile) that uses basic, simple, straightforeward
regexp's from the C library.  Initial feedback from
windows users seems  to be that the windows world
has no f**ing idea of what a regexp is; its not in
windows, its not supported by Microsoft. Somewhere,
there's some port of (gnu?) regexp libs to windows,
but rank-n-file windows programmers that I deal with
don't seem to know how to download/compile/build/install
such things.

You may have better luck with this; I don't know how to
code on windows, so I punted.

It should be available as long as Guile is configured with
`--enable-regex' (which is the default) and regcomp(3) is provided by
the C library, which I'd expect to be the case here.

Can you show the result of "grep regcomp config.log" when configured on
MinGW?

Thanks,
Ludo'.

This gives nothing but grepping for reg gave inter alia
...
configure:24696: checking regex.h usability
conftest.c:94:19: regex.h: No such file or directory
| #include <regex.h>
configure:24738: checking regex.h presence
conftest.c:61:19: regex.h: No such file or directory
| #include <regex.h>
configure:24807: checking for regex.h
ac_cv_header_regex_h=no

which I guess is relevant...

That means that either <regex.h> is simply not available in MinGW, or
it's optional, I don't know.

Thanks,
Ludo'.

You can find a suitable regex implementation at the MinGW project
download page:

http://sourceforge.net/project/showfiles.php?group_id=2435&package_id=73286

Thanks very much for the help, I'll have to look further at mingw.

Thanks - I built this and put libregex.a in the lib directory and
the .dll that it asked for on startup in the bin directory and all was
well.
