Trying to install the latest GtkAda for Mac on Mojave using Community 2018

Trying to install the latest GtkAda for Mac on Mojave using Community 2018

[ahlan]

Once upon a time, (2015), I successfully installed GtkAda 3.8.4 using Macports and then GtkAda from the sources provided in gtkada-gpl-2015-src.tar.gz and all was well.

However on buying a new Mac I tried to do the same thing but failed.
As I don't particularly want to remain on this version I have tried to install the latest and greatest.

But again without success.
Can someone give me a clue as to what I am doing wrong or what I should be doing.
Is there a better way of getting GtkAda running on my MAC?

I  installed the community 2018 version of GNAT for OSX.
Easy - so far so good.

I assume that GtkAda needs Gtk3 for Quartz and so I installed Macports 2.5.3 and then did a port install of gtk3 +quartz which installed 3.22.30
So far so good.

I then cloned the sources for GtkAda from GitHub.com/AdaCore/gtkada and then tried to build GtkAda.

Previously I changed directory to the sources and then entered

CC=/usr/bin/gcc ./configure --prefix=/Users/Ahlan/gtkada
make
make install

However the make now fails when trying to compile misc.c on line 32 
#include <stdio.h>
fatal error: stdio.h: No such file

and misc_generated.c fails to find limits.h

How is it supposed to find these files?
Do I need to install something else?
Am I installing GtkAda in the correct and recommended manner?

Any help very much appreciated.
Best wishes,
Ahlan

To part answer my own question - a better way to install GtkAda is to simply copy Xnadalib-gpl-2018-quartz-x86_64-apple-darwin 17.7.0-bin.tar that some very thoughtful chaps have made available.
This seems to be a compilation of "everything" and is built with GNAT community 2018, so the binaries and libraries are all compatible with the version of GNAT I am using.

Double plus good!

If I had known about this before I could have saved myself such a lot of time ;-)
But now I do - so a very big thanks to those involved in creating this time saving pre-built collection.

I have made a donation - not much but enough for a beer - Enjoy!

I think you may have fallen foul of Apple's latest (not installing the
header files where they ought to be): see

Dear Simon,
How right you are :-)
Typing your line of magic solves the problem.
Or at least takes me to the next.
As I wrote, I have a solution, in as much as I can simply copy the complete works as built by somebody else.
But just out of interest, and because I think I am tantalisingly close to successfully building GtkAda myself I wonder if you or anyone else can help me past the next hurdle.
When I type Make I now get

ld: unknown option: -Wl
collect2: error: ld returned 1 exit status
garlic: /users/ahlan/opt/gnat/2018/bin/gcc execution error
gprbuild: could not build library for project gtkada
make: *** [build_library_type/relocatable] Error 4

Any ideas what I should do?
Best wishes,
Ahlan

This is odd.

gprbuild (or gnatmake) calls gnatlink which calls gcc (or maybe g++)
which eventually calls the system ld with appropriate arguments.

-Wl starts an instruction to gcc to pass an argument through to the
system linker: if you say -Wl,-foo,bar then ld sees

   ld ... -foo bar ...

(see https://gcc.gnu.org/onlinedocs/gcc/Link-Options.html).

Ah! the first comma is important: I just tried this,

   $ gnatmake raiser.adb -largs -Wl
   gcc -c raiser.adb
   gnatbind -x raiser.ali
   gnatlink raiser.ali -Wl
   gcc: error: unrecognized command line option '-Wl'; did you mean '-W'?
   gnatlink: error when calling /opt/gcc-8.1.0/bin/gcc
   gnatmake: *** link failed.

Maybe there's a problem in the Makefile.

I have a configure problem!
Configure fails with 
checking for GTK - version >= 3.14.0... configure: error: pkg-config not found

brew installed gtk+3 version 3.24.10 which does contain pkgconfig/gtk+-3.0.pc

Any advice will be appreciated.
Thanks,
Roger

 I  forgot to mention that I  am using the community 2019 version of GNAT for OSX.
