[Vm-dev] Re: Cog on Linux

[Paul DeBruicker]

Hi Rob,

In case you never got a CogVM compiled:

I was able to compile to 32bit VM on 64 bit ubuntu 10.04 desktop after 
installing these packages:

lib32asound2-dev
libgl1-mesa-dev
libglu1-mesa-dev
build-essential
ia32-libs
gcc-multilib
g++multilib


Then follow the instructions here:

http://www.squeakvm.org/svn/squeak/branches/Cog/unixbuild/HowToBuild

This was the configure incantation:

../../platforms/unix/config/configure CC="gcc -m32" CXX="g++ -m32" 
CFLAGS="-g -O2 -msse2 -D_GNU_SOURCE -DNDEBUG -DITIMER_HEARTBEAT=1 
-DNO_VM_PROFILE=1 -DCOGMTVM=0" LIBS=-lpthread

Then do this:

But.  The VM will open your image, but it seg faults a short, random 
amount of time after that.  Even if you make the change Eliot recommends 
here:

Good luck.
