I would appreciate insight on a compilation error while building GCC 11 to run on Windows, targeting bare metal ARM, from a GNU/Linux build environment (specifically Ubuntu via WSL2).
I have a current (within a few days) clone of the Git repo at the HEAD of releases/gcc-11.
*** Source tree:

Your branch is up to date with 'origin/releases/gcc-11'.

Using built-in specs.

gcc version 9.3.0 (Ubuntu 9.3.0-17ubuntu1~20.04)
For better or worse, I'm using GNU Make to drive the build process from the next level up from the GCC source tree, i.e. my Make is calling $(MAKE) to invoke the GCC build. Extracting the recipe steps, here is how I'm attempting to build GCC:
Recipe steps:
# Obtain GCC source for the release branch of interest.
#
# "If you do not intend to make changes to the source, you can avoid installing these build tools by running contrib/gcc_update."
# https://gcc.gnu.org/git.html
git clone --branch releases/gcc-11 --depth 1 git://gcc.gnu.org/git/gcc.git $(COMPILER_ROOT)/gcc
cd $(COMPILER_ROOT)/gcc && contrib/gcc_update
# "If you also intend to build binutils (either to upgrade an existing installation or for use in place of the corresponding tools of your OS), unpack the binutils distribution ... in the same directory..."
# https://gcc.gnu.org/install/download.html
# https://www.gnu.org/software/binutils/
git clone --branch binutils-2_37 --depth 1 git://sourceware.org/git/binutils-gdb.git $(COMPILER_ROOT)/gcc/binutils
# "Likewise the GMP, MPFR and MPC libraries can be automatically built together with GCC. You may simply run the contrib/download_prerequisites script in the GCC source directory to set up everything."
cd $(COMPILER_ROOT)/gcc && contrib/download_prerequisites
# Configuration
# https://gcc.gnu.org/install/configure.html
#
# "The build machine is the system which you are using, the host machine is the system where you want to run the resulting compiler (normally the build machine), and the target machine is the system for which you want the compiler to generate code."
# We're going to use WSL + Ubuntu + GCC to build a toolchain to run on Windows targeting ARM.
cd $(COMPILER_ROOT)/build && $(COMPILER_ROOT)/gcc/configure --host=x86_64-w64-mingw32 --target=arm-none-eabi --prefix=${TOOLCHAIN_ROOT} --enable-vtable-verify --with-multilib-list=aprofile,rmprofile --enable-target-optspace --enable-languages=c,c++,lto --enable-large-address-aware
# Build the cross-compiler
# https://gcc.gnu.org/install/build.html
$(MAKE) -C $(COMPILER_ROOT)/build
I have made one change to a config script to get as far as I have:
$ git diff -- config/mh-mingw
diff --git a/config/mh-mingw b/config/mh-mingw

I commented out those flags because they are not recognized by GCC 9 on Linux as the toolchain building the compiler. I think these flags are only needed for a compiler that is actually running on Windows, which I am NOT doing; I am building a compiler FOR Windows.
When I encountered another error, and another beyond that, I concluded that I must be making an error myself, because I doubt that a released version of GCC would have multiple errors with respect to cross compilers.
Here is the tail end of the build output I see leading up to the error:

Granting that I am proceeding from a position of ignorance, I am not expecting an attempted invocation of "arm-none-eabi-gcc". My reasoning is that the build process is taking place on GNU/Linux, while "arm-none-eabi-gcc" is the name I expect for one of the compiler executables that will run on Windows. Just prior to the error, the GCC build copies xgcc.exe to gcc-cross.exe, which I presume is the compiler executable that will ultimately correspond to "arm-none-eabi-gcc.exe".
Because I don't know what I don't know here, I don't have a crisp question, except perhaps: where am I going astray in my thinking and/or build steps for the goal I'm trying to attain? Did I already go off the right track when I modified the config file earlier in the process?
Thanks,
Tom

The option is needed for a GCC build which *will run* on Windows.
On Windows the stack size is hardcoded in the PE executable, so it's
needed to use -Wl,--stack to set a larger stack size. On UNIX-like it's
determined run-time (with RLIMIT_STACK).
'-Wl,--stack,12582912' just passes '--stack 12582912' to the linker, and
the GNU linker targeting PE platforms supports it. If your "x86_64-w64-
mingw32-gcc" does not recognize '-Wl,--stack,12582912', it's broken.
You may remove '-Wl,--stack,12582912' and get a compiler which seems to
work (i. e. it can compile a "Hello world" program), but it will then
crash building a complex source code file.

You need to install arm-none-eabi-gcc on Linux, because otherwise you
won't be able to build libgcc for arm-none-eabi (note that "arm-none-
eabi-gcc.exe", which is just compiled, can't run on Linux). You may use
"make all-gcc" and "make install-gcc" to skip libgcc, but a GCC build
without libgcc is almost completely useless (such a build is only useful
if you'll build libgcc manually later, or you are debugging GCC itself).

My reasoning is that the build process is taking place on GNU/Linux, while "arm-none-eabi-gcc" is the name I expect for one of the compiler executables that will run on Windows. Just prior to the error, the GCC build copies xgcc.exe to gcc-cross.exe, which I presume is the compiler executable that will ultimately correspond to "arm-none-eabi-gcc.exe".
But that .exe can only run on the --host system, i.e. on Windows. To
build the target libs for the --target system (i.e. arm) you need an
arm compiler that runs on the --build host (i.e. x86_64 Linux).
So to build this combination you need to already have an arm cross
compiler to run on your build system.

Thanks for sharing this clarification, Jonathan. Although I referred to the documentation, I did not grasp the prerequisite of a native cross-compiler. The documentation takes pains to spell out the distinction among host, build, and target machines, and that they can be different from each other. Somehow, the need to start with both a native and a cross toolchain for the build machine eluded me.
Regards,
Tom

Thank you, Xi, for pointing out the need for the native cross toolchain as well as clarifying the linker flags. I installed the native Linux toolchain for bare-metal ARM, removed my config file edits, and tried again to build for a Windows host targeting ARM.
I am seeing a new error, but it seems to occur further in the build process, so I feel like I'm a step closer. More context around the error is pasted below.
checking whether the arm-none-eabi-gcc linker (/usr/lib/gcc/arm-none-eabi/9.2.1/../../../arm-none-eabi/bin/ld) supports shared libraries... yes
checking dynamic linker characteristics... no
checking how to hardcode library paths into programs... immediate
checking for shl_load... configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES.
make[1]: *** [Makefile:13331: configure-target-libstdc++-v3] Error 1
I tried explicitly adding "--disable-shared" to the "configure" script parameters, so I'm confused about why I'm seeing "... supports shared libraries... yes".
Looking at the configure script inside gcc/libstdc++-v3, it seems to test whether "gcc_no_link" is set to "yes" to trigger the error. I looked at how that variable is set, and found this:
cat confdefs.h - <<_ACEOF >conftest.$ac_ext
/* end confdefs.h. */
#include <stdio.h>
int
main ()
{
printf ("hello world\n");
;
return 0;
}
_ACEOF
# FIXME: Cleanup?
if { { eval echo "\"\$as_me\":${as_lineno-$LINENO}: \"$ac_link\""; } >&5
(eval $ac_link) 2>&5
ac_status=$?
$as_echo "$as_me:${as_lineno-$LINENO}: \$? = $ac_status" >&5
test $ac_status = 0; }; then :
gcc_no_link=no
else
gcc_no_link=yes
fi
if test x$gcc_no_link = xyes; then
# Setting cross_compile will disable run tests; it will
# also disable AC_CHECK_FILE but that's generally
# correct if we can't link.
cross_compiling=yes
EXEEXT=
else
cat confdefs.h - <<_ACEOF >conftest.$ac_ext
/* end confdefs.h. */
int
main ()
{
;
return 0;
}
_ACEOF
To my untrained eye, it looks like this is trying to link a simple "hello world" executable (ac_link='$CC -o conftest$ac_exeext $CFLAGS $CPPFLAGS $LDFLAGS conftest.$ac_ext $LIBS >&5') and if that fails, it sets this "gcc_no_link" flag to turn off further attempts to link executables?
I'm really not sure what the bigger picture is here on this build error, but I am guessing that bare metal ARM doesn't support shared libraries and somehow I have convinced the GCC build to try working with shared libraries anyway?

To: Xi Ruoyao, gcc-help, Thomas Sobczynski
Update: I kept peering at the configure scripts and their embedded comments, and concluded that it's at least worth trying to add "--with-newlib" to the configure script parameters. That may not be the right move, but it did get me further into the build process. However, although its configure script finished, the GCC build seems unable to compile libstdc++ (tail end of output below).
Am I barking up the wrong tree with "--with-newlib"?
Does it make sense that the build is supplying include search directories from the GCC v11 build tree (compiler being compiled) to the native cross compiler which is GCC v9.x? I already misunderstood the build/host/target config earlier. Is it perhaps not _a_ GCC cross toolchain that I need, but perhaps I need to build _the_ compiler (v11) and then turn around and use it to build for the non-native Host?
Thanks,
Tom

I think --with-newlib is needed, as it's the de-facto C library on bare
metal ARM. But you need to install newlib for the target before
building libstdc++, because libstdc++ needs a C library.
And your configuration may trigger
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100017, which is fixed in
GCC 11 branch recently. You may need to "git pull" your GCC 11 branch
to overcome it.
Maybe you can add --disable-libstdcxx and build a GCC without libstdc++,
reboot into Windows, and then compile newlib & libstdc++ for target with
the toolchain just built.
However, honestly I don't do any serious development on Windows...

"__has_builtin" is introduced in GCC 10, so GCC 9 can't recognize it.
IIRC libstdc++ from a specific GCC version is only expected to be built
with GCC with the same version.

Because the checks for dlopen are done whether or not you are building
.so files.
Adding --with-newlib will fix that error.
That's no longer necessary on the Git master branch, because I fixed
it yesterday, see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=103866

Yes. You are compiling the libstdc++ from GCC 11, so it has to look at
the headers for the GCC 11 version of libstdc++.
You can't use GCC 9 to compile libstdc++ from GCC 11, because GCC 9
doesn't support all the C++ features used in the GCC 11 lirbary (this
is nothing to do with cross compilation, you can never use a
mismatching version of GCC, newer or older, to compile libstdc++, it
just doesn't usually happen unless cross compiling like this).
You need a newer arm cross compiler (ideally it should exactly match
the version of GCC you are trying to build).

No.
This might help, it's a script I used last week to build a build!=host
compiler. You'll need to adjust the flags for your own case:

Strictly speaking it doesn't need one, but you have to use
--disable-hosted-libstdcxx --without-headers --with-newlib to tell it
you have no C library.
On the master branch you no longer need the --with-newlib for that
case (PR 103866). Building trunk, or backporting the fix for that bug
to gcc-11, might make life easier.

Yes, building a canadian cross for bare metal, involving Windows, is
like falling out of the ugly tree and hitting every branch on the way
down.

Correct.

Thanks much for the pointers thus far. I am now trying to take this in three chunks: build native GCC11 on GNU/Linux, then use that to build GCC11 on/for GNU/Linux targeting ARM, then use the previous two to build GCC11 on GNU/Linux for Windows targeting ARM.
The first step completes, so I have an installed GCC 11 native toolchain for Linux.
The second step doesn't finish; getting hung up on configuring libstdc++.

The excerpted recipe I'm using to build the native/native/native toolchain:
cd $(COMPILER_ROOT)/build-linux-native && $(COMPILER_ROOT)/gcc/configure --prefix=${LINUX_TOOLCHAIN_ROOT} --enable-vtable-verify --enable-languages=c,c++,lto --disable-multilib --disable-bootstrap --enable-large-address-aware
$(LINUX_TOOLCHAIN_ROOT)/bin/gcc: $(COMPILER_ROOT)/build-linux-native/Makefile
$(MAKE) -j8 -C $(COMPILER_ROOT)/build-linux-native
$(MAKE) -C $(COMPILER_ROOT)/build-linux-native install
The excerpted recipe for the native/native/cross toolchain:
cd $(COMPILER_ROOT)/build-linux-cross && PATH="$(LINUX_TOOLCHAIN_ROOT)/bin:$(PATH)" $(COMPILER_ROOT)/gcc/configure --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --target=arm-none-eabi --prefix=${LINUX_CROSS_TOOLCHAIN_ROOT} --enable-vtable-verify --with-multilib-list=aprofile,rmprofile --enable-languages=c,c++,lto --enable-large-address-aware --disable-shared --with-newlib
PATH="$(LINUX_TOOLCHAIN_ROOT)/bin:$(PATH)" $(MAKE) -j8 -C $(COMPILER_ROOT)/build-linux-cross
PATH="$(LINUX_TOOLCHAIN_ROOT)/bin:$(PATH)" $(MAKE) -C $(COMPILER_ROOT)/build-linux-cross install
The search paths the configure script is passing to the compiler do not contain 'stdio.h', but the native toolchain I'm using to compile (same GCC 11.2.x) does have it:
$ find linux-cross -name 'stdio.h'
$ find linux -name 'stdio.h'
linux/include/c++/11.2.1/tr1/stdio.h
linux/lib/gcc/x86_64-pc-linux-gnu/11.2.1/include/ssp/stdio.h
I seemed to have the opposite problem earlier, where the GCC 9 native->ARM toolchain I installed was choking on headers from GCC 11 that it couldn't understand, which is why I built a native GCC 11 in the first place. Any thoughts on where I have gone wrong this time?
Thanks,
Tom

This is fixed by the patch for PR 103866 that I already referred you
to. Either build the Git master branch, or backport the fix to gcc-11.
But I'm repeating myself now.
