New Cog VMs available
... at http://www.mirandabanda.org/files/Cog/VM/VM.r3632. These include 64-bit VMs whose Smalltalk execution and FFI are functional. However, their SocketPlugin is more than somewhat broken. Executing the SocketPlugin tests results in a hard lockup, at least on Mac OS X.

It turns out that the 64-bit socket issues are Mac OS only. The linux 64-bit VMs seem to be fine. The problems are to do with socket reuse and/or broadcast (SO_REUSEADDR, SO_REUSEPORT & SO_BROADCAST).

Hi Eliot, Since I cannot compile the VM on my own, I tried yours (compilation error as I mentioned in one of my previous emails). I tried yours, but I am not sure which VM to try. I downloaded CogPharoSpur64.app-16.08.3632.tar but I cannot open an image. Any reason why? Alexandre

You need a 64 bit pharo image for that. Stephan
I am a bit lost. Do we have a 64bits support? If yes, then why do we still have some 32 bits images? Alexandre

Hi Eliot,
Since I cannot compile the VM on my own, I tried yours (compilation error as I mentioned in one of my previous emails). I tried yours, but I am not sure which VM to try. I downloaded CogPharoSpur64.app-16.08.3632.tar but I cannot open an image. Any reason why?
Hi Alex, I am pretty sure Eliot will answer when he gets up, I answer now so you have a quicker answer. Let me explain what the file name CogPharoSpur64.app-16.08.3632.tar means: 'Cog' => VM with the jit (*not* interpreter only VM or Sista VM) 'Pharo' => for Pharo (*not* for Newspeak or Squeak) 'Spur' => Spur memory manager (*not* the SqueakV3 memory manager) '64' => 64 bits VM (*not* a 32 bits VM) '.app -16.08.3632.tar' => suffix and version number So my guess is that you are trying to run a 32 bits image with a 64 bits VM. 64 bits VM run only 64 bits images such as the ones available here <http://www.mirandabanda.org/files/Cog/SpurImages/>. Assuming you want to open a 32 bits image, you can try: CogPharoSpur.app-16.08.3632.tgz (It does not have '64' in its name so it's 32 bits) Now you might miss some libraries that might not be present in this build. Tell us if you can successfully run Roassal. If one wants to know more about the internal names, one can read the HowToBuild file from the build repository which explains that very well. Clement
