A newly added patch fixes this, which fixes the following build failure: http://autobuild.buildroot.net/results/55d6190b60a08c9bc4d659cf009df52388db676a/ Signed-off-by: Thomas Petazzoni --- diff --git a/package/libev/0001-fix-sparcv8-condition.patch b/package/libev/0001-fix-sparcv8-condition.patch new file mode 100644 index 0000000000..d411f834f5 --- /dev/null +++ b/package/libev/0001-fix-sparcv8-condition.patch @@ -0,0 +1,29 @@ +Fix SPARCv8 condition + +The define provided by the compiler on SPARCv8 is __sparc_v8__ and not +__sparcv8.
