[Gumstix-users] bitbake questions

[Mark A. <m_a...@co...>]

Hi,

I just went through the bitbake helloworld example and it worked great.  
Thanks for all the explicit instructions about using bitbake and the 
recipes.

I did go back and modify the hello.c file and reran bitbake, but it did 
not recompile the src.  The ipkg files were not updated.  It was only 
when I modified the PR variable of the recipe file, and reran bitbake 
that it really recompiled the code.  What don't I understand here?

Also,  when I download the ipkg to the gumstix and install it, the code 
is placed in the "proper" destinations, plus I am guessing any libs too 
which might be included.  So when I do a new compile and rerun "ipkg 
install xxxx" - do I first need to do an "ipkg remove (package name)" ?  
Or is it overwritten so it doesn't make a diff.

thx.
