## Compile

- The fetch speed is slow when compiling `nativesdk-glibc`.

    **Resolution**:

    Change the source settings as follows:

    1. Open the recipe file:

> 
> 
> vim <workspace>/layers/poky/meta/recipes-core/glibc/glibc_2.39.bb +35
>             Copy to clipboard
    2. Add the following line to the file:

PREMIRRORS = ""
            Copy to clipboard

> 
> 
> 3. Save the and exit.
>     4. Clean and fetch `nativesdk-glibc` again:
> 
> 
> bitbake -c cleanall nativesdk-glibc
>             bitbake -c do_fetch nativesdk-glibc
>             Copy to clipboard
>     5. After the commands finish, rebuild according to the original procedure.
