Sorry to ask this... Are you sure? Vanilla base setup with no extra packages getting gcc and various -dev packages? Perhaps there is a 'developer' profile during install that gets you a reasonable kit?

About 5 minutes ago I managed to get limited access (non-root, cannot install packages) to a cygwin env using rdesktop. It did have gcc and make, but make bombed out with a missing libcurl and openssl header files. IIRC, diff3/merge isn't in the base install either.

In debian I can look at apt-cache show git-core to get a quick overview of dependencies but here I'm lost :(

That's great to know.

Is cygwin still installable in 2 modes? (Used to be personal and system-wide or something like that.)

If that's the case, then in a system-wide install you must be root to write to /usr/local (I'm guessing here) and there's no sudo or su -c 'make prefix=/usr/local install' so you'd have to open an admin session. Can cygwin shell be invoked under RunAs?

Thanks! So no vfat. In terms of speed, this should be for a small/medium project. No linux kernel development on Windows just yet ;-)

Thanks! that's a starting point, though I'm intrigued about the packages required. Are there ways to query what packages you have installed (a la dpkg -l) and to install a list of packages from commandline?

Oh, what an ignorant fop I am.

cheers,
