Hello all,
In some point the documentation say:
"We do not support toolchains or SDK generated by OpenEmbedded or Yocto,
because these toolchains are not pure toolchains (i.e. just the compiler,
binutils, the C and C++ libraries). Instead these toolchains come with a
very large set of pre-compiled libraries and programs. Therefore, Buildroot
cannot import the *sysroot* of the toolchain, as it would contain hundreds
of megabytes of pre-compiled libraries that are normally built by Buildroot.
"
If I build the toolchain using make_standalone_toolchain.py
<https://developer.android.com/ndk/guides/standalone_toolchain.html>
it is a "pure toolchain"? it can be used in buildroot as preintstaled
toolchain?
Thanks in advance :)

We have never tested Android toolchains, so I don't know. However, what
is sure is that those toolchains use the bionic C library, which we
don't support. And you most likely won't be able to build most of the
Linux applications against bionic, at least not without some effort.
Best regards,
Thomas

But you can afaik combine a Buildroot rootfs (built against
glibc/musl/uclibc) with an android rootfs without much problems, as the
same paths aren't used. In the worst case you can do a static build.
