Really? No one on #parrot has been able to get parrot to work on Cygwin for
months. The reason has changed since this specific ticket but if you have a
working cygwin build can you please share more details such as:

perl -V
cat myconfig
perl Configure.pl
which gcc
gcc -v
windows version (usually winver from command line)
output of make (as an attachment)
strings /bin/cygwin1.dll | grep -i cygwin-1. (just need 1 line of output
to determine version of cygwin1.dll)

Cheers,

Interesting, didn't know about this.

Could you, or someone else, please add the error message to the ticket,
or create a new one? Maybe I can help with that.

It's a fairly standard Windows XP SP2 box with Cygwin, everything up to
date. I have tried to install everything optional (like ICU), too.

There's one important thing to remember. Although Cygwin may look
UNIXish, shared libraries are linked and loaded the Windows (DLL) Way.
IIRC, binaries on (some) UNIXish platforms remember their link paths, so
if you don't move the library the referrer can still find and load it.
Not so with Windows. A linked application just remembers the library
name, and the usual Windows DLL lookup applies.

On Window, which means MSWin32, not Cygwin, this is handled by copying
libparrot.dll into the root directory, where parrot.exe lives. For
Cygwin I added the blib/lib directory to the PATH. Which reminds me I
should really submit a patch for resolving this. Maybe just copy the
lib, like on "real" Windows.

Actually, if parrot can't find libparrot.dll it receives the exception
0xc0000135, which is Windows' way to say "DLL not found."

Hello, I'm Configure. My job is to poke and prod your system to figure out

It's been a while since I've posted here! I contributed a few tweaks
for Cygwin some time back to help it build a bit smoother, but haven't
tried in the last 12 months due to work commitments. However, one
thing I note is that footnote *1 in Platforms has become orphaned in
r16662, which is ironically when it was changed to Broken.

I doubt this is terribly useful, but I cannot get the cygwin build
working, and here's the output that I see. This is with r17772, which
someone claimed worked for them.

Paul

I think that's actually a good sign. Try adding the absolute path to
F<blib/lib> and try again. If this is working please see my previous
post in this thread about library loading.

Yes, that's bad.

GMP I don't know, but bc is explicitly disabled on all but selected
platforms. I have enabled it on my box a few days ago and will submit a
patch to add cygwin if it causes no problems. Also, the message should
say "skipped on this platform" or something similar, instead of "no."

Don't know if this is any help, but I'm seeing the exact output if I

Ron

Sorry, I guess there was some mental PATH overloading going on. Try
adding the absolute path to F<blib/lib> to PATH.

export PATH=/path/to/parrot/blib/lib:$PATH

And then "make."

Ron

The first libparrot.dll in PATH is used, so unless you've got an
installed Parrot it shouldn't matter.

I'm getting the same test results. That's the current state of Parrot
on Cygwin. See http://smoke.parrotcode/org/smoke section i386-cygwin-gcc.

Actually, you can't smoke parrot without user intervention.
F<t/src/io.t> seems to consume an infinite amount of memory, or at least
tries to. Haven't look into the details yet, but I think one test
creates an executable io_4.exe which doesn't stop printing results,
which cause the out of memory situation. I usually just kill io_4.exe.
(I know, that's a bad thing, but that's what bad people do.)

Not 100% on this, but I think one or two of the stm tests hang, too.

Ron

t/pmc/stmlog.t, test 2?

-- c

No, I think this one's fine. More like t/stm/queue.t test 2 and
t/stm/runtime.t test 4. Actually, t/stm/queue.t sometimes seems to work
(see cygwin smokes).

You're right, that's the missing piece. If, after a successful build, I
delete F<runtime/parrot/library/Crow.pbc>, unix2dos Crow.pir and try to
build Crow.pbc again I get the same error.

> make runtime/parrot/library/Crow.pbc
./parrot.exe -o runtime/parrot/library/Crow.pbc

OK, that gets me past that failure, but then I run into another; see
attached.
