Subject: [Buildroot] [PATCH 1/1] package/libcpprestsdk: link with libatomic when needed
Date: Fri, 15 Feb 2019 22:33:15 +0100	[thread overview]
Message-ID: <20190215213315.31969-1-fontaine.fabrice@gmail.com> (raw)

On some architectures, atomic binutils are provided by the libatomic
library from gcc. Linking with libatomic is therefore necessary,
otherwise the build fails with:

sparc-buildroot-linux-uclibc/sysroot/lib/libatomic.so.1: error adding symbols: DSO missing from command line

This is often for example the case on sparcv8 32 bit.

Fixes:
