Re: Building a cross-native toolchain to build on ARM-Android for ARM-Android

[Rein Loopalu <eesti dot elanik at gmail dot com>]

Now I ran 'file' on bin/as, here is the result:
-
arm-and-linux-gnueabi2/bin/as: ELF 32-bit LSB executable, ARM, EABI5
version 1 (SYSV), statically linked, for GNU/Linux 3.15.4, stripped
-


Doing the same for bin/gcc shows Linux 2.6.16. I wonder why are they
different and how can I make it build bin/as for older kernel?
