> Buildroot is an embedded Linux build system, which is capable of using

> toolchains are supported through this mechanism.
> I while back, Yann E. Morin, the former maintainer of Crosstool-NG,

> Those toolchains are available here:
> However, those toolchains are now one year old, and some of them have
> some issues:
> - The uClibc toolchains were built without IPv6 support, and Buildroot
> now requires IPv6 support to be present. Due to this, we had to
> disable the use of all uClibc toolchains from the above list.
> - The ARM toolchains are affected by gcc bug PR58854, causing
> lttng-tools to fail building.
> - The PowerPC toolchains are affected by gcc bug PR60155, causing a
> build problem with SDL and mpeg2.
> - The MIPS64 toolchain uses a too old glibc version, which lacks
> SYS_getdents64, causing a build failure of Python 3.
> - The MIPS uClibc toolchain fails to build gdb, weston and civetweb (I
> believe due to uClibc issues)
> Is there someone in the Crosstool-NG community interested in working

> Crosstool-NG toolchains, and fixing the above issues?
> Also, I would strongly advise Crosstool-NG to move away from uClibc,

> tons of fixes that have never been in a uClibc stable release.
I had no clue about uClibc-ng, I will definitely look into it!

I am happy to help out with providing these toolchains.
Get me on irc, and we'll discuss details!
