gnutls source code uses the C++11 <atomic> functionality since https://github.com/gnutls/gnutls/commit/7978a733460f92b31033affd0e487c86d66c643d, which internally is implemented using the __atomic_*() gcc built-ins On certain architectures, the __atomic_*() built-ins are implemented in the libatomic library that comes with the rest of the gcc runtime. Due to this, code using <atomic> might need to link against libatomic, otherwise one hits build issues such as: ../lib/.libs/libgnutls.so: undefined reference to `__atomic_fetch_sub_4' on an architecture like SPARC. To solve this, link against libatomic if BR2_PACKAGE_HAS_LIBATOMIC is set. This fix gnutls build failures as well as cups, gnupg and libmicrohttpd Fixes: - http://autobuild.buildroot.org/results/1c7541fc6ac4b52d1dfe02a9a7d61db90f4521eb - http://autobuild.buildroot.org/results/42c8803b98e38ebd48870fe6b1a20a1d6c351e5f - http://autobuild.buildroot.org/results/a1e96d02d41f7fec0f5327f65fb34405f963a1e9 - http://autobuild.buildroot.org/results/59c92706457a9da29dd44425e546a7c80c18b454 Signed-off-by: Fabrice Fontaine <fontaine.fabrice@gmail.com> --- package/gnutls/gnutls.mk | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-)
