Configuring GCC 10.3 on PPC Mac OS X 10.4.11/Tiger for build reveals flaws in configure scripts

Theory and practice are the same, in theory, but, in practice, they are different.

isl is not part of GCC, and I don't see this error in the version of
isl that gcc-10.3.0/contrib/download_prerequisites uses.

Using isl is optional anyway, you can just leave it out if you want.
Either way, this seems to be a problem with the version of isl that
MacPorts uses, not a GCC problem.

This line number doesn't match what's shown below, as it's coming from
line 13560 below (which is line 13496 in my copy of the gcc-10.30
sources, so maybe MacPorts patched it?)

This is harmless, but I see the problem and will fix it.

I'll see if I can find this one too. Also harmless though.

gcc/configure.ac has:

# Test for stack protector support in target C library.
AC_CACHE_CHECK(__stack_chk_fail in target C library,
...
       *-*-darwin* | *-*-freebsd* | *-*-netbsd*)
     AC_CHECK_FUNC(__stack_chk_fail,[gcc_cv_libc_provides_ssp=yes],
           [echo "no __stack_chk_fail on this target"])
        ;;

That AC_CHECK_FUNC comes after the earlier message which hasn't
printed its result yet, so the output of the two gets muddled. Then
the echo makes it even worse, by adding a third message inside the
other two.

Yup.  Also, GCC 10.4 was released over a month ago, please use that?
Any problem in previous minor releases might already be fixed (I doubt
it in this case, but :-) )

I can try. I was asked to try to build the MacPorts package, or "port", gcc10-bootstrap to help solve another problem on PPC Tiger/Mac OS X 10.4.11 I've seen that GCC 10.4 was out and I now know that MacPorts supports this version too:

	gcc10                          @10.4.0         lang/gcc10
	libgcc10                       @10.4.0         lang/gcc10
	gcc10-libcxx                   @10.4.0         lang/gcc10
	gcc10-bootstrap                @10.3.0         lang/gcc10-bootstrap

They have dependencies:

	Full Name: gcc10 @10.4.0_4+stdlib_flag
	Extract Dependencies: xz
	Build Dependencies:   texinfo
	Library Dependencies: cctools, gmp, isl, ld64, libiconv, libmpc, mpfr, zlib, zstd

The only port that I might be able to build is "libgcc10" which has a dependency of "libgcc11", and this a dependency to "libgcc":

	Full Name: gcc11 @11.3.0_5+stdlib_flag
	Extract Dependencies: xz

I do not understand this scheme, honestly! Very old software, that depends on software that will be created in some future? But – "libgcc12" is very easy to build:

Next month, if my internal disk will find enough empty space (remember: my PowerBook G4 is almost 20 years old, and then a 100 GB disk was no usual gadget, not even in a Mac). (It might be possible to create "private" versions on an external disk.) Before I have to find the cause why a particular port, boost, uses '-Wl,-rpath ...' which cannot work on Tiger. (It's OK with later OS versions.) It works, with other ports, when '-Wl,' is not there, because then it's a no-op or gets neglected.

Manual builds will take longer. Because they might needed patches *I* would have to provide – you've the seen the list I gave Jonathan?

Ah.  I don't know what modifications they make, but our compilers should
work without any of that.  You could try with what we distribute, and
get help from us ;-)

The problems you encountered with the modified source code you tried
might happen with unmodified code just the same, but it is hard to know
for sure unless you try, and support is much harder than needed with
unknown modified code :-(

MacPorts tells me:

	Error: gcc10 10.4.0 is not supported on Darwin 8 powerpc
	Error: Failed to fetch libgcc10: incompatible macOS version
	
	Error: gcc11 11.3.0 is not supported on Darwin 8
	Error: Failed to fetch libgcc11: incompatible macOS version

So I have to try to build manually…

Hello!

Here is my evaluation from building GCC 10.4 on PPC Mac OS X 10.4.11, Tiger, with modern tools with 40 hours. I am using in the first, leftmost column, line numbers from compile log in GNU Emacs which quantify when one of the many steps is taken. It might help classify and explain some differences between building GCC 10.3 and GCC 10.4 I encountered.

GCC 10.3 was built with old system's tools and utilities, while for GCC 10.4 I could use modernised versions. This might explain a few differences. Particularly the following:

  134:Configuring stage 1 in ./gcc
	  524:checking assembler for -mmacosx-version-min option... no
	  537:checking assembler for compressed debug sections... 0
	  549:checking linker for compressed debug sections... 0

Presumingly the old as is better integrated in Mac OS X and configure finds in GCC 10.3:

	checking assembler for -mmacosx-version-min option... yes
	checking assembler for compressed debug sections... 2
	checking linker for compressed debug sections... 0

Is this difference intended?


Three times configure finds:

 2509:configure: WARNING: could not determine output file type
10005:configure: WARNING: could not determine output file type
40270:configure: WARNING: could not determine output file type

while it finds 45 times:

	checking for C compiler default output file name... a.out

Is this difference intended?


Another (intended?) difference is this:

10.3:
	checking whether a program can dlopen itself... yes
	checking whether a statically linked program can dlopen itself... yes
	checking whether a program can dlopen itself... cross
	checking whether a program can dlopen itself... yes
	checking whether a statically linked program can dlopen itself... yes
	checking whether a program can dlopen itself... cross
	checking whether a program can dlopen itself... yes
	checking whether a statically linked program can dlopen itself... yes
	checking whether a program can dlopen itself... cross
	
10.4:
	 5673:checking whether a program can dlopen itself... no
	 6244:checking whether a program can dlopen itself... cross
	35942:checking whether a program can dlopen itself... no
	36513:checking whether a program can dlopen itself... cross
	66207:checking whether a program can dlopen itself... no
	66778:checking whether a program can dlopen itself... cross


A bit disturbing is this, finding yes and no for the same item, __int128 (because libquadmath supports this data type?):

	 5698:checking for ISO/IEC TR 24733 ... no
	 5699:checking for __int128... no

It's unlikely anybody is very interested in gcc-10 as there will only be
one more release from that branch, and most of these are just harmless
cases of unclear output. The configure script works correctly, it just
prints jumbled output.

This is perfectly normal, __int128 is supported when building 64-bit
libraries and not when building 32-bit libraries.

Libquadmath provides routines for working with 128-bit floating-point
types, not integers.
