Asp Forum - [newbie] help, I can't compile an extension on windows

Hello!

I'm on Windows2000, with ruby 1.8.2 (2004-12-25) [i386-mswin32]
(on-click-installer). I have latest mingw and VC++ installed (the
command line version) and vars are set: PATH to each bin dirs, LIB to
each lib dirs and INCLUDE to each include dirs.

I've written in a file the first sample found in pragmatic programmer's
book: http://www.ruby-doc.org/docs/ProgrammingRuby/html/ext...
----8<----
#include "ruby.h"

static VALUE t_init(VALUE self)
{
VALUE arr;

arr = rb_ary_new();
rb_iv_set(self, "@arr", arr);
return self;
}

static VALUE t_add(VALUE self, VALUE anObject)
{
VALUE arr;

arr = rb_iv_get(self, "@arr");
rb_ary_push(arr, anObject);
return arr;
}

VALUE cTest;

void Init_Test() {
cTest = rb_define_class("Test", rb_cObject);
rb_define_method(cTest, "initialize", t_init, 0);
rb_define_method(cTest, "add", t_add, 1);
}
----8<----

My first attempt was with the extconf.rb written this way:
----8<----
require 'mkmf'
create_makefile("Test")
----8<----

I launch it, I then launch make (the mingw version of make, I don't have
M$ make. Someone know where I can freely get it?)

And I get this error:
----8<----
>make
makefile:105: *** multiple target patterns. Stop.
----8<----

I'm not a make expert and I feel hard to see where the error truly lies.

I then tried it manually, as I read it on the same pragprog page (with
readaptation for my directory structure):
----8<----
>gcc -fPIC -IC:\usr\ruby\lib\ruby\1.8\i386-mswin32 -g -O2 -c
first_prag_sample.c -o first_prag_sample.o
cc1.exe: warning: -fPIC ignored for target (all code is position
independent)
In file included from C:/usr/ruby/lib/ruby/1.8/i386-mswin32/ruby.h:670,
from first_prag_sample.c:1:
C:/usr/ruby/lib/ruby/1.8/i386-mswin32/missing.h:64:1: warning: "isinf"

In file included from
C:/usr/ruby/lib/ruby/1.8/i386-mswin32/win32/win32.h:56,

from C:/usr/ruby/lib/ruby/1.8/i386-mswin32/ruby.h:22,
from first_prag_sample.c:1:
C:/usr/MinGW/include/math.h:290:1: warning: this is the location of the
previous
definition
----8<----

And then the second command line:
----8<----
gcc -shared -o Test.so first_prag_sample.o -lc
C:\usr\MinGW\bin\..\lib\gcc-lib\mingw32\3.2.3\..\..\..\..\mingw32\bin\ld.exe:
cannot find -lc

----8<----

Any clues? Any tips? Perhaps a way to do it easier with rake or rant?

IIRC, your problem is caused by the word "Test". I think it conflicts
with Kernel.test or something strange. Try changing it to "Foo" and
see how it goes. I may be off.

If you follow these instructions, you should have nmake.

Replaced all occurences of Test by Foo. The error is still exactly the same.

Makefile generated by mkmf.rb for nmake can't work with other makes.

`extconf.rb --with-make-prog=make' might help you, though I'm not
sure.

Unfortunately, it doesn't work.

Seems I'm going to dive into mkmf sources.

I have it now, and it still don't work. There is something about a
missing windows.h that I can't find anywhere. I can't find excepted in
my MinGw include dir, but if I add it to the INCLUDE var, I get another
bunch of errors (probably some kind of incompatibilities between cl
compiler and mingw headers)

You should not be mixing cl and MinGW... use whichever tool your
version of Ruby was compiled with. You can get the MS tools as a
free (your soul does not count) download if you need them.

I'll consider about it later, but mingw doesn't support msvcr7 runtime
yet, which is used by VisualC++ 7 or later.

I haven't. This what I tried to explained: if I mix them, I get errors,
so I don't.

I already have all the MS tools I should use: nmake, cl, link, and the
headers and libs, and so on. But I got the error of windows.h missing,
and there are no windows.h anywhere in MS include stuff.
