I tried posting this on the buildroot mailing list, but then thought
it's maybe more of a uClibc issue than buildroot, though I'm not too
sure. Sorry if it's not.
I've been trying to track down why re-running make after a successful
compilation of buildroot (version 2010.02) give errors, so I've been
stopping the compilation process at various points and restarting it.
Each time it restarts, it rebuilds uClibc first, which works fine until
I restart it after libstdc++ has been build and installed, then
rebuilding uClibc fails with:

I'm building on an x86 for ARM, using GCC 4.4.x, a custom Linux Kernel
V2.6.33 and this nptl version of uClibc:
39548d72297a8c3d8d55e04b8240e4ce09913a82
Snapshot:
http://git.uclibc.org/uClibc/snapshot/uClibc-39548d72297a.tar.bz2
I've enabled large file support, IPv6, locale/i18n support,
build/install c++ compiler and libstdc++ and ARM VFPU and I've enabled
the following packages:
gettext
libintl
libiconv
libglib2
I've also added mono as a package, but at the point the toolchain
breaks, it hasn't been built yet.
I'm not sure why building the C++ compiler / libstdc++ should affect
building uClibc, but it seems to. Perhaps I should be using uClibc++,
but there's no option in buildroot.
Thanks.
