I got a build error after adding 'extern unsigned int page_size' to
util/python.c - please see my previous reply.
namhyung@sejong:perf$ make
SUBDIR ../lib/traceevent/
LINK perf
GEN python/perf.so
gcc: error: python_ext_build/tmp//../../libtraceevent.a: No such file or
directory
error: command 'gcc' failed with exit status 1
cp: cannot stat `python_ext_build/lib/perf.so': No such file or directory
make: *** [python/perf.so] Error 1
The libtraceevent.a will be in
python_ext_build/tmp/../../../lib/traceevent/libtraceevent.a if make was
invoked without the O.
Makefile contains following:
TRACE_EVENT_DIR = ../lib/traceevent/
ifneq ($(OUTPUT),)
TE_PATH=$(OUTPUT)
else
TE_PATH=$(TRACE_EVENT_DIR)
endif
LIBTRACEEVENT = $(TE_PATH)libtraceevent.a
TE_LIB := -L$(TE_PATH) -ltraceevent
Thanks,
Namhyung
