Problems building master on macOS

HEAD has been broken for me for a few days, failing to configure with:

	config.status: error: cannot find input file: `src/emacs-module.h.in’

I’m not sure when this started; I noticed recently that the configure machinery had changed, had some free time, and decided to do a distclean and bootstrap. ./autogen.sh asked me to rerun ./autogen.sh git, which was fine, but configure failed near the end, unable to find the above file. I then tried again with —without-modules, to no avail.

A little digging suggests that this commit is related:

commit c66a7cce17ac4b9cde6bf49232aaa59c1c73404e
Author: Philipp Stephani <phst@google.com>

    emacs-module.h: Create emacs_env_26

    This was part of the original design of the module
    API (https://lists.gnu.org/archive/html/emacs-devel/2015-02/msg00960.html),
    but I didn't take it into account when adding the should_quit
    function.

    Instead of duplicating the environment fields or using the C
    preprocessor, use configure to build emacs-module.h.

    * configure.ac: Expand emacs-module.h template.

Digging into that commit suggests that the file was intentionally removed from autoconf control, but I’m not familiar enough with AC to be able to extricate it myself reasonably; I was able to hack it out enough to get emacs to build. I suspect that the problem won’t come up until without a bootstrap or deeper clean.

Hope that helps,
~Chad

That’s the commit that added emacs-module.h.in, in place of emacs-module.h.

I just tried building from a clean tree on macOS and it seems okay. It sounds like there’s something amiss in your checked-out tree.  Try “git clean -fdx” and “git reset --hard” (or a fresh checkout in a new tree) and see if that fixes it…

Possibly you ran into the bug where 'make clean' mistakenly removed 
src/emacs-module.h.in. I fixed that in commit 
1b75af59b305867c89271905be72a05d06a4eff4. Try getting the latest master 
and make sure 'git diff' reports no differences.

This was it exactly. Thanks to you and Ken both.

Problems building master on macOS

Howdy! I hadn't built master on macOS in a while, and I got this error:

checking for AppKit/AppKit.h... no
configure: error: The include files (AppKit/AppKit.h etc) that
are required for a Nextstep build are missing or cannot be compiled.
Either fix this, or re-configure with the option '--without-ns'.

Any idea what's going wrong? I presume it's an easy fix?

Compilation works fine for me on Macos.  Have you tried a "make
bootstrap"?

"make bootstrap" comes after configure. This is during configure, which 
happens right after autogen.


My build environment is 100% clean; git status says there are no stray 
files.

Take a look at config.log in the Emacs source directory.  It should give
some hints about why Autoconf cannot find the AppKit.h header in your
system.
