Hi, I attempted to cross-build v3.9-rc3's perf tool for an arm system today, and got the following out of the build system:
CHK libnewt Makefile:655: newt not found, disables TUI support. Please install newt-devel or libnewt-dev [...] builtin-report.c: In function ‘__cmd_report’: builtin-report.c:478:15: error: ‘K_SWITCH_INPUT_DATA’ undeclared (first use in this function) builtin-report.c:478:15: note: each undeclared identifier is reported only once for each function it appears in builtin-report.c: In function ‘cmd_report’: builtin-report.c:821:13: error: ‘K_SWITCH_INPUT_DATA’ undeclared (first use in this function) make: *** [builtin-report.o] Error 1 make: *** Waiting for unfinished jobs.... I've bisected this down to ad0de0971b: "perf report: Enable the runtime switching of perf data file". It looks like when NEWT_SUPPORT is defined, builtin-report.c gets K_SWITCH_INPUT_DATA via util/hist.h, which includes ui/keysyms.h. When NEWT_SUPPORT isn't defined, util/hist.t doesn't include ui/keysyms.h and the build fails. I'm able to reproduce the problem on my x86 desktop by uninstalling libnewt-dev. As far as I can see, we can't just always include ui/keysyms.h as it includes libslang.h (which may or may not be present if libnewt isn't, and we don't check for it independently). I'm not sure what the best way to fix this would be.
