From mboxrd@z Thu Jan 1 00:00:00 1970 From: Gwenhael Goavec-Merou Date: Tue, 12 Jan 2021 07:30:27 +0100 Subject: [Buildroot] [PATCH] package/uhd: fix build with riscV Message-ID: <20210112063027.27344-1-gwenj@trabucayre.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net From: Gwenhael Goavec-Merou When the target CPU is riscV, msgpack is unable to detect endianness with a list of errors like: uhd/host/lib/deps/rpclib/include/rpc/msgpack/pack.hpp:190:2: error: #error msgpack-c supports only big endian and little endian 190 | #error msgpack-c supports only big endian and little endian | ^~~~~ and with subsequent errors: uhd0/host/lib/deps/rpclib/include/rpc/msgpack/pack.hpp:236:46: error: there are no arguments to 'take8_8' that depend on a template parameter, so a declaration of 'take8_8' must be available [-fpermissive] 236 | char buf[2] = {static_cast(0xccu), take8_8(d)}; | This is due to a missing support for this architecture in msgpack.
