[Buildroot] buildroot for older uClibc

[daniel wilson]

Hi all,

I'm working with a legacy embedded platform which has some closed binaries
that are linked against uClibc 0.9.28.  Much as I would like to bring this
platform up-to-date, I'm reliant on these utilities for the correct
operation of various bits of hardware.  To cut a long story short, I think
I'm going to have to build myself a toolchain which links against uClibc
0.9.28 to produce software for this platform.

I've downloaded various older versions of buildroot, but none of them seem
to have this version of uClibc as an option.

Please can someone point me in the right direction ?

Many thanks in advance,

Dan Wilson.

In the current version of Buildroot, we still offer 0.9.28.3 as a
choice, but you have to enable BR2_DEPRECATED to see it.

However, be warned that the version of uClibc is not the only thing.
You have to create a uClibc with a configuration that is similar to the
uClibc that was used by the binaries at the time they were generated.
Depending on the configuration, the uClibc API/ABI changes.
