Subject: [PATCH 2/5] perf build: Fix libunwind feature detection on 32-bit x86
Date: Tue, 19 May 2015 16:05:43 +0300 [thread overview]
Message-ID: <1432040746-1755-3-git-send-email-adrian.hunter@intel.com> (raw)
In-Reply-To: <1432040746-1755-1-git-send-email-adrian.hunter@intel.com>
The libunwind feature would never detect because of the following error:
$ cat tools/build/feature/test-libunwind.make.output
/usr/lib/gcc/i686-linux-gnu/4.8/../../../i386-linux-gnu/libunwind-x86.so: undefined reference to `lzma_stream_buffer_decode'
/usr/lib/gcc/i686-linux-gnu/4.8/../../../i386-linux-gnu/libunwind-x86.so: undefined reference to `lzma_index_uncompressed_size'

/usr/lib/gcc/i686-linux-gnu/4.8/../../../i386-linux-gnu/libunwind-x86.so: undefined reference to `lzma_index_size'
collect2: error: ld returned 1 exit status
Fix by adding -llzma and re-ordering to match the dependencies.
