arm-angstrom-linux-gnueabi-gcc链接器无法链接到uclibc

标签： gcc ld uclibc angstrom-linux openembedded

我正在尝试为angstrom linux构建一个应用程序（在我的例子中使用uclibc而不是libstdc ++）。我正在使用bitbake和openembedded。使用简单的工具链，我可以通过仅添加-muclibc标志来成功构建。使用bitbake我的构建命令如下

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

-muclibc mainThread.cpp lib.cpp -lportaudio由我完成。 Portaudio（-lportaudio）已成功链接。 Uclibc（我认为）没有联系;我收到这些错误：

您真的应该使用g++来编译和链接C ++代码。它将负责为标准C ++库添加正确的包含路径和链接器选项。

可以使用gcc执行此操作，但始终使用g++进行编译和链接更容易。
