Hi Rob,<br>
<br>
In case you never got a CogVM compiled:<br>
<br>
I was able to compile to 32bit VM on 64 bit ubuntu 10.04 desktop after installing these packages:<br>
<br>
lib32asound2-dev<br>
libgl1-mesa-dev<br>
libglu1-mesa-dev<br>
build-essential<br>
ia32-libs<br>
gcc-multilib<br>
g++multilib<br></blockquote><div><br></div><div>Thanks, Paul. I've added this to the HowToBuild.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
Then follow the instructions here:<br>
<br>
<a href="http://www.squeakvm.org/svn/squeak/branches/Cog/unixbuild/HowToBuild" target="_blank">http://www.squeakvm.org/svn/squeak/branches/Cog/unixbuild/HowToBuild</a><br>
<br>
This was the configure incantation:<br>
<br>
../../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<br>
<br>
Then do this:<br>

<br>
<br>
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:<br>
