Subject: [PATCH 1/3] perf tools: Fix perf builds with clang support
Date: Wed, 4 Apr 2018 23:34:17 +0530 [thread overview]
Message-ID: <20180404180419.19056-1-sandipan@linux.vnet.ibm.com> (raw)
For libclang, some distro packages provide static libraries (.a)
while some provide shared libraries (.so). Currently, perf code
can only be linked with static libraries. This makes perf build
possible for both cases.
Fixes: d58ac0bf8d1e ("perf build: Add clang and llvm compile and linking support")
