Subject: [ptxdist] Kernel headers version in OSELAS toolchain & kernel version in the BSP
Date: Tue, 16 Apr 2013 11:58:19 +0200 [thread overview]
Message-ID: <516D20BB.5000108@optimeas.de> (raw)
Hello,
while reading the AppNote "Building Toolchain" I came across the section
about the naming convention:
The last part (kernel-3.6) defines the kernel header in use for this
toolchain. This is important, as applications
built with this toolchains must be ran at least on this kernel revision.
That means when I use the toolchain
arm-cortexa8-linux-gnueabihf_gcc-4.7.3_glibc-2.16.0_binutils-2.22_kernel-3.6-sanitized
from 2012.12.1
to build a BSP with a 3.4 kernel is wrong? I have done this without any
problem so far.
What is the recommended approach if I run in such a version conflict?
- Use older toolchains which require a different kernel version?
- Or can I simply adjust / create a new config file for e.g. kernel 3.4 ?
In the ptxconfig file are 2 kernel versions. From the upper toolchain
example:
PTXCONF_GLIBC_ENABLE_KERNEL="2.6.32"
and
PTXCONF_KERNEL_HEADERS_VERSION="3.6"
What is the difference ?
What speaks against using a very low kernel version for building the
toolchain ?
Thanks for any tips!
Best regards,
Matthias
