The first step is download the needed sources:
svn co http://www.squeakvm.org/svn/squeak/branches/Cog/platforms
svn co http://www.squeakvm.org/svn/squeak/branches/Cog/src
svn co http://www.squeakvm.org/svn/squeak/branches/Cog/unixbuild
Then, I followed the 3d. instructions from Eliot, because I want to build the VM on a 64-bit OS.
I have an Ubuntu 64 bits without special installations, I mean, installed exactly as the ISO installs, with no special packages selected.
Then, the first step is install the following packages needed to compile in 32-bit mode on 64-bit ubuntu:
lib32asound2-dev
libgl1-mesa-dev
libglu1-mesa-dev
build-essential
ia32-libs
gcc-multilib
g++-multilib
At this point I run the configuration script, but it failed with an error message for complaining about missing XShm.h. Doing a bit of googling I found that I probably need to do this:
sudo apt-get install libx11-dev libxpm-dev x11proto-xext-dev libxext-dev
Again run configure script and this time the error message was for complaining about missing X11/Intrinsic.h. Google found the solution once more time, another no istalled package:
sudo apt-get install libxt-dev
And now, the configuration script:
../../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
run ok.
Remember to run it from unixbuild/bld directory.
And finally, execute:
make install prefix=WhereYouWantTheVmToGo
And voila, the Cog vm is built!
