CogVM on FreeBSD

 
Good Morning,

I wonder what the state of the CogVM is on FreeBSD (9, 10)? The
FreeBSD port seems to build the plain squeakvm and not the CogVM?

kind regards

Cog doesn't run on FreeBSD at the moment, alas. Mainly because we lack
a FreeBSD expert who can tell us some bits around mcontexts and
ucontext_t things. If Eliot's OK with it, I can copy here the last
mail he sent me on the topic, when last he & I (mainly he!) took a run
at the problem.

I don't know what is being distributed with FreeBSD, but if you have any
problems with it, note that the interpreter VM for FreeBSD is available
from squeakvm.org at http://www.squeakvm.org/unix/

to me it looks like:

* fight bashism/gnuism.. or at least use "/usr/bin/env bash" instead
of hardcoding /bin/bash

* There seems to be quite some code that doesn't compile with clang.
(e.g. return from a function without value. this applies to plugins
with imported code and main Cog code)

* gcc/g++ doesn't exist but the usage is hardcoded in quite some
places. E.g. regenerating libtool could do wonder

* External libs/dependencies. When using COMPAT32 there is no libuuid
and I think I could do without the UUID Plugin.

* For  "backtrace" one needs to link -lexecinfo starting from FreeBSD
10.


What interests me more is how to get patches into the Cog branch? My
SCTP socket support and autoconf clean-ups never made it into the
branch.

cheers

attached are patches to modernize the usage of autoconf and remove
autogenerated configure files from the repository (it is an older
patch), the third patch is to use "mcontext_t" to fix the compilation
on FreeBSD.


src/plugins/VMProfileLinuxSupportPlugin/VMProfileLinuxSupportPlugin.c
needs to include dlfcn.h and should probably do the same on Linux.
Somebody would probably need to patch the code in the VMMaker and
including dlfcn.h on Linux should not hurt.

Somehow the linking of 'vm-display-null', 'vm-sound-null' do not work,
I end up with a .la and .a file but no 'vm-sound-null' binary. I had
to manually use the 'gcc -shared' line and link them.

Is there an easy way to see if some methods have been JITed?


kind regards

Holger,

I added an entry at http://bugs.squeak.org/view.php?id=7820 so we do not forget
about your SCTP changes.

You submit them to me.  I'm sorry I didn't integrate these but they broke the build if one didnt have the relevant library installed.  So a little more work is needed so that the VM still builds on systems that don't have the SCTP code installed.  OK?

thank you for the reply. I think I have been there before and the
configure patches I sent was the result of that work. From my point
of view the dependency chain was like this. "I need to write a
configure.ac check" -> "I need to run autoreconf to generate a new
configure" -> "autoreconf fails" -> "I clean up autoconf".
