[PATCH] Makefile.perf: make python module depend on traceevent

From: riku . voipio
Date: Thu Jun 18 2015 - 08:52:08 EST


From: Riku Voipio <riku.voipio@xxxxxxxxxx>

Building python module might fail if libtraceevent-dynamic-list
hasn't been built before:

to LDFLAGS:

GEN python/perf.so
/usr/bin/ld: cannot open linker script file /x/tools/lib/traceevent/libtraceevent-dynamic-list: No such file or directory
collect2: error: ld returned 1 exit status
error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
cp: cannot stat ?python_ext_build/lib/perf.so?: No such file or directory

Add explicit Makefile dependency to make sure libtraceevent-dynamic-list
is built before.
