RE: ok, finally trying out the uclibc patch for crosstool...

["Dan Strohschein" <dstrohschein at thewifilink dot com>]

Ok changing the mipsel.dat and rerunning demo-mipsel.sh ran for a while,
then gave me:

/home/downloads/crosstool-0.28-rc5/build/mipsel-unknown-linux-uclibc/gcc-3.3
.3-glibc-2.3.2/glibc-2.3.2/configure --host=mipsel-unknown-linux-uclibc

--with-headers=/opt/crosstool/mipsel-unknown-linux-uclibc/gcc-3.3.3-glibc-2.

What else am I doing wrong?

Thanks

That worked much better.  It actually built a toolchain!
However, the toolchain failed the "hello, c++" test for
dynamically linked executables (though static was ok).
Here's the last couple lines of the log:

+
/opt/crosstool/mipsel-unknown-linux-uclibc/gcc-3.3.3-uClibc-0.9.23/bin/mipse
l-unknown-linux-uclibc-g++ -static hello2.cc -o
mipsel-unknown-linux-uclibc-hello2-static
+
/opt/crosstool/mipsel-unknown-linux-uclibc/gcc-3.3.3-uClibc-0.9.23/bin/mipse
l-unknown-linux-uclibc-g++ hello2.cc -o mipsel-unknown-linux-uclibc-hello2
/opt/crosstool/mipsel-unknown-linux-uclibc/gcc-3.3.3-uClibc-0.9.23/lib/gcc-l
ib/mipsel-unknown-linux-uclibc/3.3.3/../../../../mipsel-unknown-linux-uclibc
/lib/libstdc++.so: undefined reference to `sqrtf'
collect2: ld returned 1 exit status

which looks a bit similar to http://gcc.gnu.org/PR8197

Perhaps dstrohschein@thewifilink.com can try out this toolchain
and report whether it worked for him at all with -static...
