Subject: sparse-llvm: link errors with LLVM 3.5.0
Date: Sun, 21 Sep 2014 18:49:18 +0000 (UTC)	[thread overview]
Message-ID: <lvn6je$63j$1@ger.gmane.org> (raw)

Hi all,

I'm getting link errors building sparse on Arch Linux, which has LLVM 
version 3.5.0.

An example:
/usr/lib/libLLVMSupport.a(Mutex.o): In function 
`llvm::sys::MutexImpl::MutexImpl(bool)':
(.text._ZN4llvm3sys9MutexImplC2Eb+0x37): undefined reference to 
`pthread_mutexattr_init'

From some discussion in [1], we found that this is most likely due to a 
change in LLVM[2] which requires the new "--system-libs" option to llvm-
config to get the list of link flags for correct linking of system 
libraries (including "-lpthread") needed by the LLVM libraries.

Kind regards,

Alain
