How to build app using WRLinux SDK

How to build app using WRLinux SDK

1. Prepare sdk
===============

In $PRJ directory, execute  
# make export-sdk
then ensure that wrlinux-8.0.0.24-glibc-x86_64-intel_x86_64-wrlinux-image-glibc-std-sdk.sh is generated in $PRJ/export.


Copy the sdk to a work directory and extract the sdk.
# cp $PRJ/export/wrlinux-8.0.0.24-glibc-x86_64-intel_x86_64-wrlinux-image-glibc-std-sdk.sh /path-to-work-dir
# cd /path-to-work-dir
# ./wrlinux-8.0.0.24-glibc-x86_64-intel_x86_64-wrlinux-image-glibc-std-sdk.sh

Setup the buid env
# source ./env.sh


2. An example for building app
==============================

a. Create a directory to create app source.

b. Generate a C file in the app source as below:

/* hello.c */
#include

int main(int argc, char *argv[])
{
    printf("Hello world!\n");

    return 0;
}


c. Generate a Makefile in the app source as below:

#Makefile for app

all:hello

hello: hello.c
    $(CC) -o $@ $^

clean:
    rm -rf hello

d. Build the app
# make
then the 'hello' is generated.
