Ian,
You can also add linker options via the configure options
--with-stage1-ldflags
and --with-boot-ldflags, q.v.
So, I read

Jonathan,
Yes, I should have said link with a C++ driver instead of link with a C++
compiler.
No, it's not equivalent, -static-libstdcxx does not imply

Jakub,
The root of the problem is because GCC required a C++ linker, but the logic in
gcc/Makefile forces the linker to be $(CC) when HOST_LIBS are

It is intentionally that way, so that one can fine tune the C++ libraries
linked into the binary with --with-host-libstdcxx, but you are responsible for

Jakub,
I undertand the reason for the --with-host-libstdcxx option. The documentation
for --with-host-libstdcxx doesn't say anything about the side

The build on Linux i386 works fine without --with-host-libstdcxx. I believe
g++ is used for linking.
I tried using a native Linux i386 GCC 4.7.1 to build

Richard,
On both Mac OS X and Linux, the link step uses gcc.
On Mac OS X, the link succeed; on Linux, the link fails.
The LINKER is selected by the following

From what I can tell from the GCC Link Options web page

I'm looking at CFLAGS_FOR_BUILD and CXXFLAGS_FOR_BUILD as a way to pass
-static-libgcc and -static-libstdc++ to the linker, respectively. In the

I'm kind of stumped at the moment to find an alternative method to pass down
linker flags without using --with-host-libstdcxx. I tried setting

After changing --with-host-libstdcxx back to
--with-host-libstdcxx='-static-libgcc -Wl,-Bstatic,-lstdc++,-Bdynamic -lm'
the build succeeds for Linux

This bug also occurs when --enable-languages=c,c++. I am building a cross

Richard,
Wrong track ... I found the problem (which also occurs when
--enable-languages=c,c++). See my posting.
