# Hi3861 Huawei WiFi Iot SDK #
################################
Note (20220706):
1. Porting from code-1.0.tar.gz in https://repo.huaweicloud.com/harmonyos/os/1.0/code-1.0.tar.gz
2. You could also find the binary from wifiiot-1.0.tar.gz in https://repo.huaweicloud.com/harmonyos/os/1.0/
3. This repo has only ported the C source files including header files and excluding pre-built libraries and object files as source.txt
4. Copy the C related header files by using fast_cp.sh, which can automatic build and copy the missing headers

Example

Default:
tool("cc") {
command = "$cc {{defines}} {{include_dirs}} {{cflags}} {{cflags_c}} -c {{source}} -o {{output}}"
depsformat = "gcc"
description = "cross compiler {{output}}"
outputs = [
"{{source_out_dir}}/{{source_name_part}}.o",

}

Rewrite:
tool("cc") {
command = "$cc {{defines}} {{include_dirs}} {{cflags}} {{cflags_c}} -c {{source}} -o {{output}}"
depsformat = "gcc"
description = "'$command',"
outputs = [
"{{source_out_dir}}/{{source_name_part}}.o",
