Hi Eliot,
 
I tried what you suggest:
1. check-out http://www.squeakvm.org/svn/squeak/branches/Cog
2. build with Cygwin bash
 
It took some digging, but I found my "C" drive in the dir structure of cygwin and found Cog.  I cd into cygwinbuild and 'make'.  I get the following error:

Hi Eliot,
 
Is it possible someone has generated another experimental VM for revision 16?  I am hoping so.  I have attempted to make with cygwin with poor results.  Here is what I did:
 

These steps are now obsolete.  Instead simply check-out http://www.squeakvm.org/svn/squeak/branches/Cog and build.  I've updated the build instructions there-in.  One thing wrong with the old HowToBuild is its specifying the use of a cmd shell instead of a cygwin bash shell.

1.  Install the latest cygwin (cygwin 1.7.5-1)
2.  Download and un-tarball OpenSourceCog-oscog.16.tar.gz
3.  Download VMMaker-oscog.16.mcz
4.  Download Cog-eem.40.mcz
5.  Read README and cygwinbuild\HowToBuild
6.  Try to svn checkout code (platforms, src, cygwinbuild)
    - ERROR svn: OPTIONS of 'https://dev.qwaq.com/svn/XXX/trunk/platforms': Could not resolv
e hostname `dev.qwaq.com': The requested name is valid, but no data of the reque
sted type was found.
 (https://dev.qwaq.com)
7.  Since platforms and src are already there, try make.  Command prompt - cd into cygwinbuild and make.  Error listed below.
8.  Run VMMaker-Squeak4.1.image image in image and regenerate sources.  Had to edit the directory separator from '/' to '\'.  Regenerated sources.
9.  Run make again and unsurprisingly get the same error.

Hi Rob,

    you're running a Cog VM derived from VMMaker-oscog.11.  VMMaker-oscog.16 has some important fixes.  You might want to update.

Subject: [Vm-dev] Squeak 4.1 VM crash





I am running the Cog image on the stock Squeak 4.1 vm.  I was testing the
Cryptography package.  There are two test cases that are now failing:
CryptoRigndaelCBCTest>>#testByteArrayFromHexString and
CryptoX509Test>>#testSignatureValidation for unknown reasons.

I decided to Run Coverage.   I am not really sure what this does, but I was
trying to find a way to get performance numbers and then compare to the Cog
VM.

I got the attached crash dump.
