So, before this patch:
[acme@ssdandy perf]$ make
BUILD: Doing 'make -j8' parallel build
config/Makefile:425: No libunwind found. Please install libunwind-dev[el] >= 1.1 and/or set LIBUNWIND_DIR
config/Makefile:709: No libbabeltrace found, disables 'perf data' CTF format support, please install libbabeltrace-dev[el]/libbabeltrace-ctf-dev
Auto-detecting system features:
... dwarf: [ on ]
... glibc: [ on ]
... gtk2: [ on ]
... libaudit: [ on ]
... libbfd: [ on ]
... libelf: [ on ]
... libnuma: [ on ]
... libperl: [ on ]
... libpython: [ on ]
... libslang: [ on ]
... libunwind: [ OFF ]
... libdw-dwarf-unwind: [ on ]
... libbabeltrace: [ OFF ]
... zlib: [ on ]
... DWARF post unwind library: libdw
It tries to build babeltrace in, does not find the devel files, emits that "No libbabeltrace found"
and then marks it as OFF, ok.
Now, I am ok with the intent of this patch, but... After applying it we get:
[acme@ssdandy linux]$ cd -
/home/acme/git/linux/tools/perf
[acme@ssdandy perf]$
[acme@ssdandy perf]$ make
BUILD: Doing 'make -j8' parallel build
config/Makefile:423: No libunwind found. Please install libunwind-dev[el] >= 1.1 and/or set LIBUNWIND_DIR
config/Makefile:713: No libbabeltrace found, disables 'perf data' CTF format support, please install libbabeltrace-dev[el]/libbabeltrace-ctf-dev
Auto-detecting system features:
... dwarf: [ on ]
... glibc: [ on ]
... gtk2: [ on ]
... libaudit: [ on ]
... libbfd: [ on ]
... libelf: [ on ]
... libnuma: [ on ]
... libperl: [ on ]
... libpython: [ on ]
... libslang: [ on ]
... libunwind: [ OFF ]
... libdw-dwarf-unwind: [ on ]
... zlib: [ on ]
... DWARF post unwind library: libdw
GEN common-cmds.h
It continues trying to find babeltrace, does not find it, emits the warning and
just doesn't show the OFF message :-\
Can you explain _why_ this is needed? I.e. is it to speed up feature checking?
In what way, etc. For casual readers the intent of this patch may be difficult
to grasp, no?
What am I missing?
