Subject: Re: [PATCH 1/2] perf report: Find lib path correctly for gtk option

Hi,

$ ./perf report --gtk
GTK browser requested but could not find libperf-gtk.so


When I print buf in setup_gtk_brower() in ui/setup.c:

$ ./perf report --gtk
/libperf-gtk.so
GTK browser requested but could not find libperf-gtk.so

Besides, LIBDIR path is just ""

Does it mean that LIBDIR path could not take the prefix contained to
Makefile.perf?
