Do you mean you want to put the files of Eclipse and ROOT on the USB disk, and have the main computer execute the programs - or is you USB "disk" more clever than that and have it's own PU? If it's the first option you're going for, I see no reason why not.

Download Eclipse an ROOT (and other dependencies). Plug-in your disk which will be assigned some "drive-letter" (tsk, stupid Windoze parlance) - say E:. Run the installer of the various programs, but make sure to install on the "E: drive". That's it.

One caveat. Some programs may need stupid silly "registry entries" - if that's the case, you can probably not run the program in question from the USB disk on another computer on which the program was not installed. Of course, you can try to figure out exactly which registry entries you need, and make some small ViralBasic script that puts those entries in the registry.

Yeah, please elaborate.

Which is major benefit to ROOT btw.

Which is simple:

	rem MyCmdScriptToSetROOTEnvironmentVariables.bar 
	@ECHO OFF 
	SET ROOTSYS=E:\ROOT
	SET PATH=%ROOTSYS%\bin;%PATH%
	rem Execute ROOT 
	%ROOTSYS%\bin\root.exe %1 %2 %3 %4 %5 %6 %7 %8 %9
	rem EOF

Erhm, Eclipse, is _not_ a compiler. Eclipse is an Integrated Development Environment that can use a variety of compilers, linkers, debuggers, and what not. All Eclipse needs, is for someone to define a plug-in/environment for a given toolkit. For example, there could be an environment for Sun JAVA, GCC Java, GCC C++, Micros**t ViralC--, Intel C ++, and what not. However, it does look like CDT (the C++ developmenttop posting tools) only support GCC at the moment, but I'm not 100% sure.

wxDec-C++ (the heir-taker of Dev-C++) does add support for M$ C-- in later version. However, you still need the compiler - perhaps the "express" edition will do.

Wouldn't it be nice if there was a UI standard for compilers, such that front-ends like BlurryStudio, Dev-C++, Eclipse, Anjuta, and what not, could all use the all compilers? In the Free World, we're used to that.

Yours,
