Mac OSX 10.15.7
XCode 12.0

I am attemting to build using the insttructions provided by the README.BUILD from the source distribution of GNAT.

I configure successfully from my /opt/GNAT/2021/obj directory with

.../src/configure --enable-languages="c,ada" --disable-libada --with-gmp=/usr/local/Cellar/gmp/6.2.1 --with-mpfr=/usr/local/Cellar/mpfr/4.1.0 --with-mpc=/usr/local/Cellar/libmpc/1.1.0

Although My /usr/local/include directory does include libintl.h
make bootstrap fails with:
In file included from ../../src/libcpp/charset.c:21:
.../../src/libcpp/system.h:279:10: fatal error: libintl.h: No such file or directory
#include <libintl.h>

Assistance with solving this problem will be greatly appreciated.

I think those instructions are rather old. Two things:

* usually, GCC build instructions say not to make the build directory a
subdirectory of the source
* nowadays you don't need to --disable-libada and then "make -C gcc
gnatlib gnattools"

What compiler are you starting from?

What stage of the build did this fail at? (stage_current in the build
directory)

It looks as though this is to do with "Native Language Support (NLS),
which lets GCC output diagnostics in languages other than American
English". The configuration documentation at
https://gcc.gnu.org/install/configure.html suggests --disable-nls (which
is what I do) or --with-included-gettext.

Thanks for the advice which has been quite helpful.
I have progressed but still, after quit a long time the build fails.
My current method:
In src/gcc/Makefile.in change the path to the system headers on the build machine to:
BUILD_SYSTEM_HEADER_DIR = /Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/usr/include

Follow instructions in gnat-2021-20210519-19A70-src/src

../src/configure --enable-languages="c,ada" --with-gmp=/usr/local/Cellar/gmp/6.2.1 --with-mpfr=/usr/local/Cellar/mpfr/4.1.0 --with-mpc=/usr/local/Cellar/libmpc/1.1.0 --disable-nls --disable-libstdcxx

make boostrap

results in:

This seems to be the relevant command and first error message preceding many other warning and error messages before final failure:

This failure is way beyond my understanding of the build process.
Thanks.

I don't know what happened but the problem has changed even when rebuilding from scratch (original tar balls).

In src/gcc/Makefile.in change "path to the system headers on the build machine" to:
BUILD_SYSTEM_HEADER_DIR = /Library/Developer/CommandLineTools/SDKs/MacOSX..sdk/usr/include
then, from build directory:

.../src/configure --enable-languages="c,ada" --with-gmp=/usr/local/Cellar/gmp/6.2.1 --with-mpfr=/usr/local/Cellar/mpfr/4.1.0 --with-mpc=/usr/local/Cellar/libmpc/1.1.0 --disable-nls
followed by make bootstrap produces:

After numerous failed attempts I decided to try on my laptop
OSX 10.13.6 High Sierra
Xcode 10.1
Took many hours but built and installed successfully.
I then copied the built system to my Catalina computer and ran make install which went fine until:

However, installation appears to have been successful to some extent:
obj % /usr/local/bin/gnat --version

I've yet to see if it actually works.

I build with --disable-libsanitizer; GNAT CE 2020 didn't. See the
configure options with $prefix/bin/gcc -v

My options:
https://github.com/simonjwright/building-gcc-macos-native/blob/gnat-ce/gcc.sh

I can't justify some of them :-(

Thanks, I'll try some.
