[Bug bootstrap/22259] New: spawnv cannot execute gcc/as

[fxcoudert at gcc dot gnu dot org]

Building gcc on i686-pc-mingw32 fails with:

/home/FX/ibin/./gcc/xgcc -B/home/FX/ibin/./gcc/ -B/mingw/i686-pc-mingw32/bin/

executable: C:/msys/1.0/home/FX/ibin/gcc/cc1.exe
executable: C:/msys/1.0/home/FX/ibin/gcc/as
xgcc.exe: _spawnv: No such file or directory

[lines beginning with "executable:" are debug statements printing the executable
argument to pex_win32_exec_child, in libiberty/pex-win32.c]

In fact, xgcc cannot be used. It tries to execute gcc/cc1.exe, which works fine,
then gcc/as. gcc/as is a script, and not a real win32 executable program. Thus
the spawn fails.

I don't know when this stopped to work. Seems that "before", the assembler was
called directly and not by this script. Does someone know when this changed, and
does someone have an idea on how to fix this?

Looks related to bonzini's 2005-06-16 patch
(http://gcc.gnu.org/ml/gcc-cvs/2005-06/msg00667.html). Adding him to Cc list.

One option: have gcc/Makefile stamp-as target test "build" and output
appropriate script to MS Windows BATCH file as.bat.

*) case "$build" in \
    *mingw32*) echo 'XXX' > as.bat \
       ... ;;
    *) echo '#!$(SHELL)' > as; echo 'exec $< "$$@"' >> as ; \
       chmod +x as ;; \
    esac
esac

assuming that GCC execing "as" will find as.bat.  The link/copy for other
directories using as$(exeext) might also cause problems.  So one might need to
place the mingw32 test as the outer case and separate the entire logic for ./*,
../*, and * between mingw32 and everything else.

A workaround is to specify the full path to as in configure script, eg

--with-as=/mingw/bin/as.exe --with-ld=/mingw.bin/ld.exe --
with /nm=/mingw/bin/ld.exe

I tried to copy the assembler in the tree, instead of making a script pointing
to it. It works. Is there any drawback to this approach?

Created an attachment (id=9192)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=9192&action=view)
Patch

Attached patch implements the idea of making a special case for mingw32 in
stamp-as, stamp-collect-ld and stamp-nm (gcc/Makefile.in).

It does fix this problem.

bonzini, you assigned the bug to yourself, but I haven't seen any patch or
comment to my proposed patch. I'm still looking for someone to okay that patch,
or propose a better way to do it. The number of patches needed to build mingw32
is still growing, so i'd like to get this one fixed.

I don't like the patch, the correct way is to teach pex-win32.c about '#!'
because GCC is built under a Unix-like environment (MSYS).

>From what I have seen on the gcc ml, it looks like the opposition to a
pex-win32.c patch (Mark) agrees on it, and Christopher said in
http://gcc.gnu.org/ml/gcc-patches/2005-08/msg00513.html he could do it. Adding
him to the PR. Maybe the assignment should be changed, too.
