            Bug ID: 109460
           Summary: Build gcc for win32 failed in gcc13 master branch
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: fanghuaqi at vip dot qq.com
  Target Milestone: ---

Hi there, I tried to build gcc 13 for windows host using mingw gcc in linux.
But I am facing the following issue.

i686-w64-mingw32-g++  -fno-PIE -c /work/gcc/gcc/config/i386/sym-mingw32.cc
sym-mingw32.o
i686-w64-mingw32-g++: error: sym-mingw32.o: No such file or directory
echo timestamp > s-bversion

It seems the sym-mingw32.o is not generated via this command, and I thought it
should be like gcc -c hello.c -o hello.o, so I changed
gcc/config/i386/x-mingw32-utf8

diff --git a/gcc/config/i386/x-mingw32-utf8 b/gcc/config/i386/x-mingw32-utf8

This issue disappeared, but other issue like this happened, I didn't have ideas
to  how to fix it.

[Bug c/109460] Build gcc for win32 failed in gcc13 master branch

--- Comment #1 from Costas Argyris <costas.argyris at gmail dot com> ---
Can you give some more info on how exactly you are cross-building gcc for
windows host?

Did you add the -fno-PIE flag manually or was it part of the build process you
are following?

Seems like you are trying to compile an executable out of sym-mingw32.cc, but
this shouldn't be happening because this file gets compiled into a simple
object file only.    That's why it would help to know more about the build
process you are following.

-fno-PIE is automatically set when the compiler is built.

The missing -o looks genuine, does not it?

sym-mingw32.o : $(srcdir)/config/i386/sym-mingw32.cc
        $(COMPILER) -c $< $@

Note that:

tf8-mingw32.o : utf8rc-mingw32.o sym-mingw32.o
        $(COMPILER) -r utf8rc-mingw32.o sym-mingw32.o -o $@

can be rewritten using $^ instead of repeating the prerequisites.

--- Comment #3 from Costas Argyris <costas.argyris at gmail dot com> ---
"The missing -o looks genuine, does not it?"

Not to me because this has been built successfully before.    If this was the
problem then it would never build, right?

What happened in this case was that sym-mingw32.o was treated as an input to
the compiler (see "No such file or directory" error) rather than as an output
which it really is.

I suspect this had to do with -fno-PIE triggering building an executable, which
I still don't know where it is coming from and whether it should be used for
compiling this file, as this has nothing to do with an executable - we are only
compiling the .cc file to a .o file.

Still I think it is important to have details of the overall build process
followed to get some context.

This looks like a bug in any case and thus needs to be fixed.

Yes, because -o is missing.

-fno-PIE is just a standard -f compilation option, nothing more.

>> Yes, because -o is missing.

I don't understand why -o missing is a problem some times but not others
(because this has been succesfully built before with -o missing).

Adding a "-o" flag seems OK to me if it solves this issue, but Huaqi still
reported problems even after adding it:

utf8-mingw32.o: In function `WinMainCRTStartup':
...

this object file should never have such a function, so something went very
wrong in this build process.    Looks like something was attempted to get built
as an executable, when it shouldn't.    All three object files:

utf8rc-mingw32.o
sym-mingw32.o
utf8-mingw32.o

should be without any such main function.    What caused this main function to
appear in this object file in this particular build process?

I think it might be introduced by this commit
https://github.com/gcc-mirror/gcc/commit/304c7d44a2212e6fd618587331cea2c266dc10bf,
since I tested this commit
https://github.com/gcc-mirror/gcc/commit/4872e46e080c6695dfe1f9dc9db26b4703bc348c
it works for win32 build. After this commit, it failed.

Still can't do much without detailed info on how exactly you are building gcc,
what is your build setup, what is your cross-compiler version, OS, how you
configure etc etc...    Ideally, solid reproduction steps would be optimal.   
Also, isolated logs from a single file are not that helpful, could you please
paste more context from the build log around the error?

Also, is this happening only for the 32-bit windows host, meaning that the
64-bit windows host is succeeding, or you haven't tried the 64-bit windows host
at all?

The patch you pointed at has been built successfully with some common build
setups, both cross and native, for both 32 and 64-bit windows hosts, so it
can't be completely broken - we just have to figure out what is different in
your particular build process and is causing problems, which is why I am asking
for more info and reproduction steps.

Also, as I said before, the fact that you ended up with this line:

utf8-mingw32.o: In function `WinMainCRTStartup':

indicates that something went horribly wrong because these object files have no
relation to any main function, and yet they were somehow attempted to be built
as executables.    This should never have happened, so I am curious how exactly
you ended up in this situation.

--- Comment #8 from Costas Argyris <costas.argyris at gmail dot com> ---
Are you building the cross-compiler itself or just using an existing
cross-compiler to build for the windows host?

You may have to build the cross-compiler first from the latest gcc sources, and
then use that newly-built cross-compiler to build the same gcc sources into a
windows-hosted compiler.

Hi, Costas Argyris,

I am using this repo to help build toolchain, the repo link is here:

https://github.com/riscv-collab/riscv-gnu-toolchain

clone this source code and its submodule, and change gcc to upstream version

git clone https://github.com/riscv-collab/riscv-gnu-toolchain.git
git submodule update --init --recursive --depth 1
cd gcc
# fetch upstream gcc source code
git fetch --all
git checkout master
cd ..

Tested in Ubuntu 18.04, with packages binutils-mingw-w64-i686
gcc-mingw-w64-i686 g++-mingw-w64-i686 binutils-mingw-w64-i686 installed and
other requirements in
https://github.com/riscv-collab/riscv-gnu-toolchain#prerequisites.


build command:

mkdir build
cd build
../configure --prefix=$(pwd)/install --with-host=i686-w64-mingw32 
--enable-multilib
make -j16

Then you will be able to reproduce this issue.

Thanks

Hi Huaqi,

This is building a larger project, which gcc is part of.    I am not familiar
with that larger project and I have never built it.

Could we extract only the gcc-specific part out of the entire build process,
such that I can reproduce the gcc build failure on its own, just by using gcc's
configure?    In other words, I would like to debug gcc's build process only,
not a larger project's build process which includes building gcc.    If there
is indeed a problem with gcc due to that patch, it should be possible to
isolate it and reproduce it by building gcc only by itself.

--- Comment #11 from Costas Argyris <costas.argyris at gmail dot com> ---
As I said before, I think adding the "-o" flag to

$(COMPILER) -c $< -o $@

is a good and harmless change, but, as per your own report, it didn't solve
your issues because you still got that mysterious line:

utf8-mingw32.o: In function `WinMainCRTStartup':

which doesn't make sense to me.    This makes me suspect that the problem is
something else and not the abscence of "-o".    These object files have nothing
to do with such main functions that are associated with executables.    So
unless you come up with gcc-specific reproduction steps for me to investigate,
you have to figure out why this object file even has a WinMainCRTStartup
function after adding the "-o" flag.

I also noticed you are using gcc 7.3 as the cross-compiler.    Would it be
possible to use a more recent version, just to see if that makes a difference?

--- Comment #18 from Costas Argyris <costas.argyris at gmail dot com> ---
For some reason you are compiling gcc/utf8-mingw32.o as an executable, which
shouldn't be happening.

This is the rule for it in gcc\gcc\config\i386\x-mingw32-utf8

utf8-mingw32.o : utf8rc-mingw32.o sym-mingw32.o
        $(COMPILER) -r utf8rc-mingw32.o sym-mingw32.o -o $@

This simply takes the two .o files and combines them into one.    No
executables or main functions are involved here whatsoever.

Did you perhaps change anything in this rule while trying to fix it?   
Otherwise I don't know why your utf8-mingw32.o has a main function and mine
doesn't.

The linker comes to mind - I noticed your gcc is configured to explicitly use:

--with-ld=/usr/bin/i686-w64-mingw32-ld

but I don't know why that would cause such behavior.

You are also getting a bunch of errors like this:

/usr/bin/i686-w64-mingw32-ld: Dwarf Error: Could not find abbrev number 101.

which again are coming from the linker.

It's the -r option passed to the compiler, it was not really supported in older
compiler (and certainly not documented).

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=109460

--- Comment #24 from Costas Argyris <costas.argyris at gmail dot com> ---
So this is because of the old (7.3) gcc version not supporting -r.

Indeed, in the 7.3 doc

https://gcc.gnu.org/onlinedocs/gcc-7.3.0/gcc/Link-Options.html#Link-Options

there is no '-r' option while there is in the current doc:

https://gcc.gnu.org/onlinedocs/gcc/Link-Options.html#Link-Options

However, I don't understand how the proposed solution works:

+       $(COMPILER) -r -nostdlib utf8rc-mingw32.o sym-mingw32.o -o $@

since we are still using the -r flag which we just found out doesn't work in
7.3

The fact that -nostdlib somehow makes it work seems like magic to me, and I
can't propose such a patch for that reason.    I also don't know if this fixes
this case of using an old compiler but breaks others.

If Eric feels confident about this and can test that it doesn't break currently
working builds, please propose a patch.

Thanks

As I said on IRC, even GCC 4.8 passes -r through to linker invocation, but only
since
r9-2994 gcc -r acts effectively the same as -r -nostdlib, before that one had
to use both options to avoid linking crt files, standard libraries and the like
even during the relocatable link.
An open question remains if mingw/cygwin supports other host compilers for
stage1, like clang, icc, msvc and the like, and whether -r or -r -nostdlib
works for those.

Yes, if we could avoid partial linking altogether, that would be best.

[Bug bootstrap/109460] Build gcc for win32 failed in gcc13 master branch

I am not aware of any cases of building windows-hosted gcc with msvc or clang.

If the combination -r -nostdlib fixes this case without breaking all the others
that don't need -nostdlib (which sounds like it is the case), then I suggest we
move forwards with this solution.

Created attachment 54841
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=54841&action=edit
New patch including -nostdlib next to -r

Tested this in cross-compile from Debian (building the cross-compiler itself as
well) and native-compile from Windows in MSYS2.

Didn't try building with earlier gcc version myself because OP reported that
the fix worked for them using gcc 7.3

If you are wondering why this PR wasn't automatically updated by the commit, I
am wondering the same thing.

You need to note "PR109460" or preferably "PR bootstrap/109460" in the
changelog.

You can paste the commit message here yourself, but let me do that for you :-)

mingw: Support building with older gcc versions

The $@ argument to the compiler is causing
only a warning in some gcc versions but an
error in others. In any case, $@ was never
necessary so remove it completely, just like
the rules in x-mingw32 where the object file
gets named after the source file.

This fixes both warnings and errors about
sym-mingw32.o appearing in the command line
unnecessarily.

The -nostdlib flag is required along with -r
for older gcc versions that don't apply it
automatically with -r, resulting in main
functions erroneously entering a partial link.

Hi Huaqi,

Patch has been pushed to master, you should now be able to get the latest gcc
sources and build without having to apply it manually.

Regarding usage of the -r flag:

Building windows(mingw)-hosted gcc with clang at this point seems highly
experimental at best, and impossible with msvc.

With clang (lld linker), -r is supported with ELF, but not with COFF (windows).

This sounds like incomplete support on the lld side though, and therefore not
something that should prevent us from using -r (I think lld should support it
for COFF as it does for ELF, because it is meant to be a drop-in replacement
after all).
