Error building primus with clang #189

Closed slacka closed 5 years ago

slacka commented 8 years ago

Trying to build primus with clang results in: ./gl-passthru.def:2:1: error: unknown attribute 'ifunc' ignored [-Werror,-Wunknown-attributes]

The full log of this error can be found here: http://clang.debian.net/logs/2016-08-30/primus_0~20150328-4_unstable_clang.log

It appears that Clang supports the ifunc attribute only starting from version 3.9, and your log indicates that 3.8 was used.

Apologies for relying on this unportable feature, but alternative approaches have drawbacks too.
