+clang 3.9 add this warning to rightly flag undefined
+behavior, we relegate this to be just a warning instead
+of error and keep the behavior as it was. Right fix would
+be to not pass enum to the function with variadic arguments
+as last named argument
+
+Fixes errors like
+ocsp.c:2220:22: error: passing an object that undergoes default argument promotion to 'va_start' has undefined behavior [-Werror,-Wvarargs]
+ va_start(ap, responseType0);
+ ^
+ocsp.c:2200:43: note: parameter of type 'SECOidTag' is declared here
+ SECOidTag responseType0, ...)

Add a patch to disable a clang specific warning and avoid passing clang options to gcc when we have cross compiler is clang but host compiler is gcc We do not need to use target cflags when building native pieces and hence avoid the inter-mixing of compiler options Signed-off-by: Khem Raj <raj.khem@gmail.com> --- .../nss/nss/disable-Wvarargs-with-clang.patch | 33 ++++++++++++++++++++++ .../nss/nss/nss-fix-nsinstall-build.patch | 11 ++++---- meta/recipes-support/nss/nss_3.24.bb | 2 ++ 3 files changed, 41 insertions(+), 5 deletions(-) create mode 100644 meta/recipes-support/nss/nss/disable-Wvarargs-with-clang.patch -- 2.9.0 -- _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-core
