Following up a little more: I decided to try running under windows
cmd.exe, instead of mingw. That didn't have any effect.
Frustrated, I rebuilt the ragel within mingw entirely, starting from
"./configure".
That has apparently solved the problem. The same command line as
described below now completes with no errors reported, and running ragel
-V produces a .dot file that looks like what I expect.
Woo-hoo!
Can I request an option, --vis-char-transitions (defaulting to "on") to
emit character based transitions as quoted letters instead of integer
numbers during visualization?
That is, in the dot generator, produce something like:
1 -> 2 [ label = "'o'" ];
Instead of the current:
1 -> 2 [ label = "111" ];
(At least whenever isgraph(ch)?)
Thanks,

This is on windows (32bit, XP pro sp3, en-us), using the binary
distribution linked from the ragel home page. FWIW, I'm invoking the
commands under Mingw bash.
I've attached some output from procmon, with the good bits at about
line 135. The file is apparently located and successfully read, but
then somehow ragel decides to fail.

I've been unable to reproduce this problem using the ragel 6.6
distribution tarball on my ubuntu lucid system. Can you tell me which
architecture you are on? Where did you get the build? Also, could you
attach an strace log?
Thanks,

Howdy,
I was playing a bit with Ragel, and trying to include one machine from
another. I spent some time with a "graph lookup ... failed" error,
until
I put my test file in the same place.
As a test case, I have this:
===== testinc.rl =====
%%{
machine inner;
one = "one";
two = "two";
}%%
===== test.rl =====
%%{
machine test;
include inner "testinc.rl";
main := one;
}%%
===== =====
When I have test.rl and testinc.rl in the same directory, I can do
ragel test.rl
with no problems. When I move testinc.rl to a different directory:
mkdir x
mv testinc.rl x
ragel test.rl
I get errors (as expected):
test.rl:3:28: include: failed to locate file
test.rl:3:28: include: attempted: "testinc.rl"
test.rl:5:10: graph lookup of "one" failed
When I then specify the include path:
ragel -I x test.rl
I get:
$ ragel -I x test.rl
test.rl:5:10: graph lookup of "one" failed
Apparently ragel now finds the included file okay, but for some reason
the exact same file which worked before has problems with finding the
"one" tag.
What am I doing wrong, or is this a bug?
