我需要一些帮助来使用这里创建的工具链来编译一个简单的hello世界 . 或者我错过了什么 .

即使我不确定为什么这些标志设置如下：

--with-gxx-include-dir = / not / exists / usr / include / c /5.2.0

--with-SYSROOT = /不/存在

经过编译后，最终尝试了很多选项

@debian：〜$ echo $ CC

arm-poky-linux-gnueabi-gcc -march = armv7-a -marm -mthumb-interwork -mfloat-abi = hard -mfpu = neon -mtune = cortex-a9 - sysroot = / opt / poky / 1.8 / sysroots / cortexa9hf-VFP，霓虹灯狭小-Linux的gnueabi

@debian：〜$ $ hello.c -o out

@debian：〜$ echo $？ 0

运行从SDK生成的"env"脚本文件后，默认情况下导出CC，CXX，LDFLAGS等变量标志，
您需要在make文件中或手动使用这些变量 .

运行sdk env

@debian:~$  . envoiment file  
@debian:~$ echo $CC
        arm-poky-linux-gnueabi-gcc -march=armv7ve -mfpu=neon -mfloat-abi=hard -mcpu=cortex-a7 --sysroot=/home/siva/imx7-images/sdk/meta-toolchain_sdk/sysroots/cortexa7hf-neon-poky-linux-gnueabi   

@debian:~$ ${CC} hello.c -o hello

如果您使用c文件，则需要使用 CXX

@debian:~$ ${CXX} hello.cpp -o hello

它会成功运行 . 所以对于每件事你只需要使用宏 .
