When you run cygwin.bat, that starts a login shell. When you start bash from emacs, that is just a regular shell, not a login shell. The difference matters as to which files bash reads (e.g. /etc/profile, ~/.bashrc, ~/.profile, etc.) Read "man bash" section INVOCATION. If some aspect of the PATH is only set in the profile then it will only occur for login shells. Though normally once an environment variable is set, it is inherited in subshells, so I don't know why your PATH is not inherited correctly. The default set of startup scripts that comes with Cygwin should be correct in terms of having a correct PATH set for you, even in subshells, but it's possible you stumbled upon a situation where something needs to be fixed. You will have to investigate the contents of your startup files and the manner in which emacs invokes the shell in order to find out why. It could also have to do with the fact that emacs probably launches /bin/sh by default (not bash), which has its own rules for which startup files to read (e.g. sh does not know about ~/.bashrc.) I can't really tell you more off-hand because a) I have long since modified most of my startup files and b) I don't use emacs. You'll have to trace it through to find out what's going on. You might add a "set +x" to the top of all such files to make them print out the commands as they're being executed. > I'd also like to make this compile with msvc using the MSVC version of the > gd library I downloaded from boutell.com.
