Missing rpc.h header in Linaro AArch64 Cross Toolchain

[Van Duc Uy]

Dear All,
During compile AArch64 with Linaro-4.7 external toolchain, busybox can not compile because missing rpc.h header file.
I copied header file from toolchain source, but it missing another header file is rpc/pmap_port.h with not found in source either.

Bug or feature?

AFAIK (e)glibc intentionally removed the sunrpc bits so they could be replaced with tirpc (which does provide rpc.h).

Most distributions tend to hack those headers back into (e)glibc, but it may be better to start telling people to use tirpc...

[Zhenqiang Chen (zhenqiang-chen)]

Yip. Eglibc-2.16 by default does not include the RPC functions and include files in favour of TI-RPC.

I have local patch to enable RPC in our build scripts (will commit after 2013.01 release). A local build is shared at:
http://people.linaro.org/~zhenqiangchen/

Please try it.

cross toolchain is still at eglibc 2.16????? Please update to 2.17 in 13.02 - there were far too many userspace problems with 2.16.

[Matthew Gretton-Dann (matthew-gretton-dann)]

In reference to comment #2 - I don't think we should be enabling the deprecated RPC features, especially as upstream GLIBC is also deprecating these features.

I think we should be providing TI-RPC somewhere, but am not convinced that the binary toolchain is the right place.

[Van Duc Uy (uvan)]

@Zhengqiang: compiled OK with your toolchain.

[Marcin Juszkiewicz (hrw)]

Ok, the problem re-appears with OpenEmbedded due to it's use of RPC from eglibc. If we want to use Linaro cross toolchains with OE then we have to provide RPC headers.

Switching OE to use libtirpc would cost us more engineering time.

[Marcin Juszkiewicz (hrw)]

OK. We have to enable RPC in eglibc. TI RPC is not mature enough for OpenEmbedded guys - for example it lacks NIS support which is required by people working with networking devices.

Zhenqiang: can I get test versions of both toolchains?
