Is there some sort of general pathname-rewriting/normalizing facility I can exploit in Emacs to allow source files in compile-mode to be translated to local paths based on remote paths? I was hoping to use symbolic links, but that’s not working for me in Windows.
I’m running GNU Emacs 23.1.1, and have tried cygwin-mount and w32-symlinks.el (with (customize-option 'w32-symlinks-handle-shortcuts)); I can’t get open-file/dired/completions OR compile-mode next-error to follow either windows shortcuts or cygwin symlinks.
I’m remotely compiling (over ssh) and the warnings/errors give filenames where a prefix of the absolute pathnames (e.g. /nfs/topaz) on the remote host needs to be replaced with a different path (z:/, in fact), which I was hoping to do with symbolic links.
/ does go to (gets tab-expanded to in emacs) c:/cygwin and ~ to z:/ (my $HOME).
What I’m hoping for is either: a fix for symlink resolution (tab completion or opening a windows shortcut gets me the .lnk file and not what it points to), or the ability to supply a list of rewrites for prefixes of pathnames. Junctions aren’t an option because the replacement path I want is on a different drive (it’s also a Samba mount).
This is also useful in other complicated build environments: I use OpenWRT, and the build process copies (or extracts) source code to a separate build directory in which compilation occurs. So naively following file names in the emacs compilation buffer leads to edit the temporary copies, not the originals. Dangerous.
