| |
Make the default build options a more preferred set, such as making BPF skeletons default and failing the build if jevents or libtracevent dependencies fail. The binutil dependencies are opt-in given license restrictions. abi::__cxa_demangle demangling support is added so that libiberty, from binutils, isn't necessary for C++ demangling.
Some build/test dependencies are fixed and the code cleaned up.
Ian Rogers (13): perf build: Support python/perf.so testing perf build: Make BUILD_BPF_SKEL default, rename to NO_BPF_SKEL perf build: Remove unused HAVE_GLIBC_SUPPORT perf build: Error if no libelf and NO_LIBELF isn't set perf util: Remove weak sched_getcpu perf build: Error if jevents won't work and NO_JEVENTS=1 isn't set perf build: Make binutil libraries opt in tools build: Add feature test for abi::__cxa_demangle perf symbol: Add abi::__cxa_demangle C++ demangling support perf build: Switch libpfm4 to opt-out rather than opt-in perf build: If libtraceevent isn't present error the build tools headers: Make the difference output easier to read perf build: Remove redundant NO_NEWT build option
