From 203db2952bc87f5d610c9ad53a7d02b85897721f Mon Sep 17 00:00:00 2001 From: Mathias Krause Date: Wed, 15 Jun 2011 23:03:38 +0200 Subject: tools/perf: Fix static build of perf tool 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.
