[Gumstix-users] Re: Build Root Version 483 Issues

[Craig H. <cr...@gu...>]

Karl,

I notice that it says "gcc" a lot below, rather than arm-linux-gcc --  
looks a lot like the zlib being built is host-native, not a cross- 
compiled version targetting the gumstix.  That's probably why the  
link step is failing, because it's trying to link an ARM binary with  
a non-ARM one.
