I'm trying to use it but hit this:
[acme@sandy linux]$ make -C tools/perf/ O=/home/git/build/perf /home/git/build/perf/perf.s make: Entering directory `/home/git/linux/tools/perf' CC /home/git/build/perf/perf.s perf.c: In function ‘handle_options’: perf.c:111: error: ‘PERF_HTML_PATH’ undeclared (first use in this function) perf.c:111: error: (Each undeclared identifier is reported only once perf.c:111: error: for each function it appears in.) perf.c: At top level: perf.c:238: error: ‘PERF_VERSION’ undeclared here (not in a function) make: *** [/home/git/build/perf/perf.s] Error 1 make: Leaving directory `/home/git/linux/tools/perf' [acme@sandy linux]
Do I have to go to tools/perf and do it from there, trying...
[acme@sandy perf]$ make O=/home/git/build/perf /home/git/build/perf/perf.s CC /home/git/build/perf/perf.s perf.c: In function ‘handle_options’: perf.c:111: error: ‘PERF_HTML_PATH’ undeclared (first use in this function) perf.c:111: error: (Each undeclared identifier is reported only once perf.c:111: error: for each function it appears in.) perf.c: At top level: perf.c:238: error: ‘PERF_VERSION’ undeclared here (not in a function) make: *** [/home/git/build/perf/perf.s] Error 1 [acme@sandy perf]$ make O=/home/git/build/perf perf.s make: *** No rule to make target `perf.s'. Stop. [acme@sandy perf]$
Same result, what am I doing wrong?
