ARM-Angstrom-Linux-Gnueabi-GCC Linkeer non riesce a collegarsi a UCLIBC

Question

Sto cercando di creare un'applicazione per Angstrom Linux (che utilizza UCLIBC invece di libstdc ++, nel mio caso).Sto usando Bitbake e apribile.Con un semplice toolchain sono in grado di costruire con successo aggiungendo solo la bandiera -muclibc.Con BitBake il mio comando Build è il seguente

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

.

dove -muclibc mainThread.cpp lib.cpp -lportaudio è fatto da me.PortAudio (-lportaudio) è collegato correttamente.UCLIBC (penso) non riesce a essere collegati;Ottengo questi errori:

Dovresti davvero usare g++ per compilare e collegare il codice C ++.Si prenderà cura di aggiungere la giusta include percorsi e opzioni del linker per la libreria C ++ standard.

È possibile farlo con gcc, ma usare sempre g++ sia per la compilazione che per il collegamento è molto più semplice.
