That's acceptable. How did you install gcc and those libraries in teh first place? From some maemo package somewhere on the net? Did you cross-compile them yourself Or would an ordinary deb from Debian armel work? > There are some things missing which prevent this approach from working > in the general case: > primarily there is no autotools, so you cannot run configure on > downloaded sources, and dpkg-* tools do not install without some major > tweaking. > > I have also installed and use c++ and vala on the device, however both > of these take the incremental compilation time just above my frustration > threshhold. > > Also, if you go down this route, I suggest you use a removable memory > card as your build location - it tents to be a vigerous process with > lots of file writes along the way - you would not want to risk burning > out your internal MMC card.
