Compiling issue with Boost asio - boost

Question

My goal is to cross-compile a code file with Yocto SDK on my host machine to make it executable on my target Board. I am using SUMO Yocto version and GCC 7.3 cross compiler.
First of all, to get with YOCTO cross compiling I created a file Hello.c :
#include <stdio.h>
int main(void)
{
printf ("Hello World!\n");
return 0;
}
I compiled the file executing :
make hello
Now I have a compiled file which is ready to be executed on my target board.
But now I have multiple .h files and multiple .cpp files and a main file.
When I execute main file like this :
make main
an error occurs:
main.cpp:10:10: fatal error: boost/asio.hpp: No such file or directory
include ^~~~~~~~~~~~~~~~ compilation terminated.
: recipe for target 'main' failed make: *** [main] Error 1
I think that I have a problem with Boost and asio.hpp.
Is the boost library included in my Yocto Linux image ?
What is the problem with asio.hpp ?
How can I fix this please ?
Thanks

I just noticed that, actually, you're not using the SDK but the toolchain which only includes glibc along with some basic tools and gdb; usually used to build test apps and debug. So that, you need to build the real SDK which contains, in addition to the toolchain, the dev version (libs/headers/other files) of the packages installed in the rootfs of your image. This can be accomplished by:
bitbake -c populate_sdk <your_image>
Once the SDK is built you need to install it through the generated installer script. Also, don't forget to source the environment setup script before you start to work!
