perf tools: Add feature check for libbabeltrace
Adding feature check for babeltrace library [1], which will be used for
perf data file CTF [2] conversion in following patches.
The babeltrace library is now automatically detected as standard
feature. It's possible to specify LIBBABELTRACE_DIR make variable to
specify location of installed libbabeltrace, like:
$ make LIBBABELTRACE_DIR=/opt/libbabeltrace/
BUILD: Doing 'make -j4' parallel build
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: [ on ]
... libbabeltrace: [ on ]
... libdw-dwarf-unwind: [ on ]
... zlib: [ on ]
... DWARF post unwind library: libunwind
NOTE The installation of the [1] to to used by above make:
$ git clone git://git.efficios.com/babeltrace.git
$ cd babeltrace
$ vim README
$ ./bootstrap
$ ./configure --prefix=/opt/libbabeltrace
$ make prefix=/opt/libbabeltrace
$ sudo make install prefix=/opt/libbabeltrace
Please make sure that the /opt/libbabeltrace/lib directory is in your
LD_LIBRARY_PATH:
$ export LD_LIBRARY_PATH=/opt/libbabeltrace/lib
