Cocoa not detected when building on macOS 10.13

Cocoa not detected when building on macOS 10.13

[Aaron Jensen]

Hi,

I’m not sure what I’m doing wrong, but when I build the emacs-26
branch on macOS 10.13 I don’t get cocoa specific features like
ns-transparent-titlebar

Is detection broken for 10.13?

Fwiw, this is what I ran to configure:

#!/usr/bin/env bash
export PATH="/usr/local/opt/gnu-sed/libexec/gnubin:$PATH"
export LDFLAGS="-L/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk/usr/lib
-lxml2 -lz -lpthread -licucore"
./autogen.sh
./configure CFLAGS="-I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk/usr/include/libxml2
-I/usr/local/opt/imagemagick@6/include" \
            --disable-dependency-tracking \
            --disable-silent-rules \
            --enable-locallisppath=/usr/local/share/emacs/site-lisp \
            --infodir=/usr/local/Cellar/emacs-plus/HEAD-d4c3669_2/share/info/emacs
\
            --prefix=/usr/local/Cellar/emacs-plus/HEAD-d4c3669_2 \
            --with-ns \
            --disable-ns-self-contained \
            --with-modules \
            --with-xml2 \
            --with-gnutls \
            --with-imagemagick \
            --with-rsvg \
            --without-dbus \
            --without-pop \
            --without-makeinfo

I can’t think of any reason it should be.

Are you sure you’re testing the features correctly? Transparent
titlebars are enabled like so:

    (set-frame-parameter nil ’ns-transparent-titlebar t)

And if that’s not working then I wouldn’t expect things like native
fullscreen to work either, and I’d expect a _lot_ of warnings during
compilation.

If it’s definitely not working, try compiling and running this:

#include <stdio.h>
#include <AvailabilityMacros.h>

void main(void)
{
  printf("MAC_OS_X_VERSION_MAX_ALLOWED: %d\nMAC_OS_X_VERSION_MIN_REQUIRED: %d\n",
         MAC_OS_X_VERSION_MAX_ALLOWED, MAC_OS_X_VERSION_MIN_REQUIRED);
}

# clang test.c ; ./a.out

and send the output back to me.

(I realise it would be easier to just look in AvailabilityMacros.h,
but I can never work out where those files are actually kept.)

That was my mistake, sorry about the confusion. It’s working now,
thank you. I was also wondering if
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=28512 was due to this,
but it seems like it is actually detecting cocoa, so this is likely
just a 10.13 issue.

Thanks,

Aaron
