I need some some help here to compile a simple hello world using tool-chain created here. Or am I missing something.

Even I am not sure why these flags sets like this:

--with-gxx-include-dir=/not/exist/usr/include/c++/5.2.0

--with-sysroot=/not/exist

After so many options tried finally through with compilation

@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-neon-poky-linux-gnueabi

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

@debian:~$ echo $? 0

After running the "env" script file generateed from SDK,by default exports the variable flags like CC, CXX, LDFLAGS etc.,
You need to use those variables in your make files or manually.

run 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

if you use c++ files you need to use CXX

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

it will run successfully. so for every thing you have to use macros only.
