brazo-angstrom-linux-gnueabi-gcc enlazador no logra realizar el enlace en contra de uclibc

Question

Estoy tratando de crear una aplicación para angstrom linux (que utiliza uclibc en lugar de libstdc++, en mi caso).Estoy usando bitbake y openembedded.Con un simple conjunto de herramientas que soy capaz de construir con éxito mediante la adición de sólo -muclibc de la bandera.Con bitbake mi comando build es la siguiente

arm-angstrom-linux-gnueabi-gcc -march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp -mthumb-interwork -mno-thumb --sysroot=/home/hnsl/stuff/tmp/sysroots/armv7a-angstrom-linux-gnueabi -fexpensive-optimizations -fomit-frame-pointer -frename-registers -O2 -ggdb2 -Wl,-O1 -Wl,--hash-style=gnu -muclibc mainThread.cpp lib.cpp -lportaudio

donde -muclibc mainThread.cpp lib.cpp -lportaudio es hecho por mí.Portaudio (-lportaudio se vincula con éxito.Uclibc (creo) no estar vinculados;Tengo estos errores:

Usted realmente debe usar g++ para compilar y enlazar el código de C++.Él se encargará de añadir el derecho de incluir rutas y de opciones del vinculador de la biblioteca estándar de C++.

Es posible hacerlo con gcc, pero siempre con g++ tanto para compilar y vincular es mucho más fácil.
