我正试图为中风气铺设申请(在我的案件中使用校准而不是校准)。 我正在使用假肢和开张。 有了简单的工具链,我就能够成功地建立起来,只添加<代码>-muclibc旗帜。 绕开我的建筑指挥是:

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

www.un.org/spanish/ga/president Portaudio (-lportaudio) 成功链接。 Uclibc(我认为)没有联系;我发现这些错误:
