Build problems on cygwin + win emacs 24.5.1

[dimitriv]

Hi, my setup is: Windows-based emacs 24.5.1 + Cygwin. I am not using Cygwin's emacs. I try installing either through melpa, or through just command-line make and I get 16-17 failures during the make compile target. From the command line, for example:

In toplevel form:
haskell-hoogle.el:30:1:Error: Searching for program: no such file or directory, /bin/bash

In toplevel form:
haskell-menu.el:34:1:Error: Searching for program: no such file or directory, /bin/bash

In toplevel form:
haskell-decl-scan.el:104:1:Error: Searching for program: no such file or directory, /bin/bash

In toplevel form:
haskell-commands.el:29:1:Error: Searching for program: no such file or directory, /bin/bash

It seems that all errors are on lines that require haskell-mode, which -- however -- I think has been built successfully (I do see a haskell-mode.elc in the build directory). Is this a known issue somehow? What is the proper fix?

What's your value of shell-file-name? If it's /bin/bash then try changing it to your preferred shell. Emacs uses this variable to invoke shell commands. You can test if it works by using M-!.

Also see this as it could just be a path issue.

Ok it had indeed something to do with emacs (being a windows version, installed somewhere else) using wrong values for several things. I made it build in the following way:

• First, add the following option --eval '(setq shell-file-name "C:/cygwin/bin/bash.exe")' to the compile target in the Makefile. Btw setting the shell variable from my .emacs file did not work (though kept it there too to get my M-x shell working.)
• Second, the $(CURDIR) path in the autoloads target was pointing to nowhere (z:/cygdrive/....) (!) so I also hardcoded that to the current directory we were building.

Pretty hacky so I am not really recommending this as an update, but at least that's what worked for me.

That's because the makefile uses emacs -Q, which doesn't load your init file.

Second, the $(CURDIR) path in the autoloads target was pointing to nowhere (z:/cygdrive/....) (!)

Is that different from where you called make from? If it is, then that seems like a cygwin problem.

If you set your Windows path correctly for cygwin and it still doesn't work, then using the Melpa version should work as the compilation happens after/when you load your init file.

This should be fixed by #1334.

Note there are plenty of other places with functionality never tested on Windows os most probably not working.
