Bug ID: 91826
Summary: Mesa 11.0.0-rc2 - state_trackers/clover does not build
on FreeBSD
Product: Mesa
Version: 11.0
Hardware: x86-64 (AMD64)
OS: FreeBSD
Status: NEW
Severity: normal
Priority: medium
Component: Other
Assignee: mesa-dev@lists.freedesktop.org
Reporter: k...@rainbow-runner.nl
QA Contact: mesa-dev@lists.freedesktop.org
Mesa 11.0.0 rc2 doesn't build on FreeBSD with the build failure below. Used
compiler is Clang 3.6.1 and we use llvm's libc++ as c++ standard library.
This seems to be that clang is picky about this piece of code. A quick test
shows that GCC 5.2.1 build the code just fine, even if it issues a warning
about the issue clang errors on.
Sorry my c++ know how is almost non existing, so can't help with making a patch
for this issue.
Clang:
