Are you sure your entire compiler is up to date, not just the library? And the
build and install directories are clean? Because your first lines of failure
involve bits of the library which *require* a consistent simultaneous change in
the C++ front-end, and well, nobody is experiencing similar problems anywhere.
Not that this code is target-independent.

CC-ing Jason, the author of such code, to be sure.

Well, on 4.4 branch there was a patch introducing the winsup link, which got
necessary for building libstdc++. We solve this by setting up in gcc's source
tree a symbolic link "winsup" pointing to the sysroot (prefix) directory.

Cheers,
Kai

No.. it was not lasest snapshot (20090331).

I move to gcc-4.4.0-20090407, create symbolik link to my prefix directory
(/usr/win64), but build not successfully..

There is a possibility of manual build.. call make with these options
make -j9 CFLAGS="-g -O2 -DNULL=0" CXXFLAGS="-g -O2 -DNULL=0

and compile remaining parts of gcc from root build directory, but it is not too
convenient...

I see this bug in compiler driver is already known
(http://sourceforge.net/forum/forum.php?thread_id=3091795&forum_id=723797), it
works only with "-O0". I can't found report about this bug in database.. does
it exists ?

> Well, on 4.4 branch there was a patch introducing the winsup link, which got necessary for building libstdc++. We solve this by setting up in gcc's source tree a symbolic link "winsup" pointing to the sysroot (prefix) directory.


Symbolic link "winsup" to prefix directory with mingw-w64 runtime headers not
works properly with current gcc 4.4.0 snapshot.. for correct build you must
*temporary* remove file "stddef.h" from
${YOUR_PREFIX}/x86_64-pc-mingw32/include because it conflicts with same file in
libstdc++ build directory.

Yes, there is already one. But this bug is work-a-round by a temporary hack in
our crt. So it shouldn't appear anymore.

Hmm, I tested a native build with current 4.4 gcc and I had no issues about it.

Please make sure, that you have in your gcc source root directory the symbolic
link "winsup" pointing to your prefix directory. Secondly, make sure you have
the symbolic link "mingw" in your prefix directory, which has to point to
x86_64-pc-mingw32 directory.
If you need further help you can join #mingw-w64 on irc.oftc.net.

Cheers,
Kai

I use Gentoo Linux x64 as build OS with system compiler gcc 4.3.3,
configuration script arguments you can see in my first post. Both symbolic
links were created.. existing stddef.h file in winsup/mingw/include causes
error: 'NULL' was not declared in this scope during libstdc++ building (see my
earlier post).

Alltimes use -O0 is not the solution.. temporary CRT hacks too. Where I can get
more information about this bug ?

Why using all time -O0? This bug you reference to is not related to your
bootstrap issue.
So, the only issue I see here are the following possible reasons (beside the
possibility of wrong symbolic links, which you have shown to setup properly).
Do you use for native toolchain an fresh initialized directory?
Which version of toolchain you are using (especially header-set)?
Do you use --prefix and --with-sysroot options?

You can try the following. Remove in your <prefix> directory the folder
lib/gcc/x86_64-pc-mingw32/4.4.0/ and remove in your gcc's build directory the
x86_64-pc-mingw32 folder. Then do a 'make'. This error can happen also, when
the sysroot headers are copied too late (after the 'make all-gcc', because
fixinclude get executed already here).

Cheers,
Kai

I use directory with mingw-64 runtime installed as --prefix= and
--with-sysroot= argument. Toolchain versions:
binutils 2.19.1
gmp 4.2.4
mpfr 2.4.1
CRT and pthreads - last versions from
http://sourceforge.net/project/showfiles.php?group_id=202880

No any changes.

I try to build gcc with latest CRT from svn (revision 764) - build is OK. It
seems, snapshot from sourceforge download page(November 15, 2008) not
compatible with gcc 4.4.

Well, this is true. We'll release soon the gcc 4.4 version is out of the door.
Of course we will update the crt/header-set tarball also.

Thanks and cheers,

Hi, I have same question when build MinGW on Ubuntu, i use Cross compiler.
and, can you tell me: where is the "winsup" patch? and how to create a link to
gcc's source?
Thanks!
