Since we are cross compiling using Yocto, and it was designed to build a
Linux OS, some assumptions are made by default, with the addition of
TCLIBC=newlib (or baremetal in any case), we get rid of those
assumptions, and in the process we get rid of the default configuration
parameters, the problem is that we only want to get rid of a few, so
basically we want to get the ones that we want back from the defaults.
Although,I believe the easiest way to understand it, is to remove this
and test this yourself, in this case if you remove this, you'll see that
GCC fails to find the correct include files, since one of the things we
get rid of is the --sysroot parameter.
Cheers,
Alejandro
I'm afraid I did not understand the problem, perhaps because I'm no
toolchain expert. Do you think there's a way to briefly clarify to
non-experts what issue is being fixed? It would be nice to have.
And, joining Jean-François in the nitpickers club... :)
Not sure what's the coding style convention in the Yocto world, but I'd
rather wrap lines at 80 chars and remove space-before-comma.
