Can install manually, but not with recipe

[lispstudent]

I am able to use complex recipes, like org-mode.

But with some, I am experiencing the following behavior (as an example, 'bbdb'):

Executing this:

(defconst el-get-sources
  '((:name bbdb)))
(el-get 'sync (mapcar #'el-get-source-name el-get-sources))

I get error:

'.' is not recognized as an internal or external command,
operable program or batch file.

And see this in the backtrace:

Debugger entered--Lisp error: (error "el-get: ./autogen.sh el-get could not build bbdb [./autogen.sh]")
  signal(error ("el-get: ./autogen.sh el-get could not build bbdb [./autogen.sh]"))
  error("el-get: %s %s" "./autogen.sh" "el-get could not build bbdb [./autogen.sh]")
[...]

But if I run this elisp snippet, autogen.sh and ./configure run just fine:

(let
    ((default-directory  "c:/home/.config/emacs/el-get/bbdb/"))
  (shell-command "./autogen.sh")
  (shell-command "./configure" ))

This is with latest el-get on Emacs 27.1 running from Windows 10 with MSYS2 as shell.

(setq explicit-shell-file-name "C:/msys64/usr/bin/sh.exe")
(setq shell-file-name "sh.exe")

Could somebody please give me some pointers on how to fix this?

It seems Emacs can find the shell and all the commands, including make, etc, but not if executed directly.

I also tried @npostavs suggestion given here, to no avail.

In my case,

(add-to-list 'exec-path "c:/msys64/usr/bin")
(setenv "PATH" (mapconcat #'identity exec-path path-separator))

I was able to have BBDB recipe work within Windows + MSYS2 by adding this line to it:

:build/windows-nt (("sh" "autogen.sh") ("sh" "configure") ("make"))

The whole recipe would be:

    (:name bbdb
       :website "http://bbdb.sourceforge.net/"
       :description "The Insidious Big Brother Database (BBDB) is a contact management utility."
       :type git
       :url "https://git.savannah.nongnu.org/git/bbdb.git"
       :load-path ("./lisp")
       ;; if using vm, add `--with-vm-dir=DIR' after ./configure
       :build `(("./autogen.sh") ("./configure") ("make"))
       :build/windows-nt (("sh" "autogen.sh") ("sh" "configure") ("make"))
       :features bbdb-loaddefs
       :autoloads nil
       :info "doc")

Would this be the canonical way to fix such issues?

Would it be fine to submit PRs for such cases?

Thanks for merging! 👍
