That’s right - a virtual machine. Virtualization is the technology that is going to save the world.
No really - not kidding. Actually running two VMs on a dual core machine with double everything is more power-efficient than having two single core machines.
But what it is also very good for is to have an entire development set-up, that you dont even have to boot up - since you can just “save state” for a VM. And you can drag along the single 2 GB file to a windows, mac, unix machine and your choice of OS and all software and tools are there for you to enjoy.
Just dont ask it to play music - VMs get a little screwy there.
Anyway, my Virtual Machine Manager is VirtualBox. But dont use the Open Source Edition (OSE) yet - its got some issues with USB on linux.
Anyway, I needed a setup with QT and about 50 other toolkits chained in a particular way for it to be usable. I figured out then, that it was no use configuring it on my laptop. I cant hope to ask someone else to replicate it.
So I went about creating a minimal Ubuntu 8.10 + KDE minimal 4.2 + lots of screwy libs. Now I did not want to use the stock Ubuntu install CD to install the OS on a VM. I wanted a minimal custom OS with all the goodness of Ubuntu repositories behind me (sorry Arch).
So I took a Ubuntu install cd - pressed F4 on the install screen and installed a “minimal commandline system”. Then it was time to install kdelibs, kdebase, kdebase-bin, kdebase-plasma, kwin, kdebase-workspace, kde-workspace-data, kdebase-workspace-bin, kdm, g++, gdb, python-qt4, python-qt4-dev and you were good to go
Oh and do remember to install “linux-headers-
