arm-angstrom-linux-gnueabi-gcc 링커가 uclibc와 연결되지 않습니다.

Question

저는 angstrom linux (이 경우에는 libstdC++ 대신 uclibc를 사용합니다) 용 응용 프로그램을 빌드하려고합니다. 나는 bitbake와 openembedded를 사용하고있다. 간단한 toolchain으로 나는 -muclibc 플래그 만 추가하여 성공적으로 빌드 할 수 있습니다. bitbake 내 빌드 명령을 사용 -muclibc mainThread.cpp lib.cpp -lportaudio이 나에 의해 수행되는 다음

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 

입니다. Portaudio (-lportaudio)가 성공적으로 연결되었습니다. Uclibc (나는 생각한다)는 연결되지 않는다. 당신은 정말 컴파일 및 링크 C++ 코드에 g++를 사용해야합니다

Answer 1

: 나는 이러한 오류를 얻을. 표준 C++ 라이브러리에 대한 올바른 include 경로 및 링커 옵션을 추가합니다.

gcc으로 가능하지만 항상 g++을 사용하면 컴파일 및 링크가 훨씬 쉽습니다.
