Subject: [PATCH] tools/perf: fix static build of perf tool
Date: Wed, 15 Jun 2011 23:03:38 +0200 [thread overview]
Message-ID: <1308171818-20370-1-git-send-email-minipli@googlemail.com> (raw)
To build a statically linked version of the perf tool all needed
libraries must be added in the correct order to get the symbols
resolved. Currently this is broken when, e.g. python or newt support is
enabled -- libpython needs libpthread which is an unconditional link
dependency of the perf tool; libslang needs libm, another unconditional
dependency. To solve the problem in the long run without the need to
keep track of transitive library dependencies, simply make the linker
look at the EXTLIBS multiple times until it has all symbols resolved.
