Building Cog VM on Ubuntu Lucid Lynx

Finally I decided to build Cog on my Ubuntu 10.04 box.

The first step is download the needed sources:

     svn co
     svn co
     svn co

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:


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!
