Not really, Wang, we need to update that feature detection test to state what is the minimum required LLVM/clang version, one that has those functions, which, unfortunately, isn't the one in the latest fedora, fedora 25: [acme@jouet linux]$ rpm -q llvm-devel clang-devel llvm-devel-3.8.0-1.fc25.x86_64 clang-devel-3.8.0-2.fc25.x86_64 [acme@jouet linux]$ LINK /tmp/build/perf/libperf-gtk.so INSTALL GTK UI /tmp/build/perf/libperf.a(libperf-in.o): In function `perf::createCompilerInvocation(llvm::SmallVector<char const*, 16u>, llvm::StringRef&, clang::DiagnosticsEngine&)': /home/acme/git/linux/tools/perf/util/c++/clang.cpp:56: undefined reference to `clang::tooling::newInvocation(clang::DiagnosticsEngine*, llvm::SmallVector<char const*, 16u> const&)' /tmp/build/perf/libperf.a(libperf-in.o): In function `perf::getModuleFromSource(llvm::SmallVector<char const*, 16u>, llvm::StringRef, llvm::IntrusiveRefCntPtr<clang::vfs::FileSystem>)': /home/acme/git/linux/tools/perf/util/c++/clang.cpp:68: undefined reference to `clang::CompilerInstance::CompilerInstance(std::shared_ptr<clang::PCHContainerOperations>, bool)' /home/acme/git/linux/tools/perf/util/c++/clang.cpp:69: undefined reference to `clang::CompilerInstance::createDiagnostics(clang::DiagnosticConsumer*, bool)' /home/acme/git/linux/tools/perf/util/c++/clang.cpp:76: undefined reference to `clang::CompilerInstance::setInvocation(clang::CompilerInvocation*)' /home/acme/git/linux/tools/perf/util/c++/clang.cpp:78: undefined reference to `clang::EmitLLVMOnlyAction::EmitLLVMOnlyAction(llvm::LLVMContext*)' /home/acme/git/linux/tools/perf/util/c++/clang.cpp:79: undefined reference to `clang::CompilerInstance::ExecuteAction(clang::FrontendAction&)' /home/acme/git/linux/tools/perf/util/c++/clang.cpp:82: undefined reference to `clang::CodeGenAction::takeModule()' /home/acme/git/linux/tools/perf/util/c++/clang.cpp:68: undefined reference to `clang::CompilerInstance::~CompilerInstance()' /tmp/build/perf/libperf.a(libperf-in.o): In function `perf::getModuleFromSource(llvm::SmallVector<char const*, 16u>, llvm::StringRef, llvm::StringRef)': /home/acme/git/linux/tools/perf/util/c++/clang.cpp:92: undefined reference to `clang::vfs::getRealFileSystem()' /home/acme/git/linux/tools/perf/util/c++/clang.cpp:92: undefined reference to `clang::vfs::OverlayFileSystem::OverlayFileSystem(llvm::IntrusiveRefCntPtr<clang::vfs::FileSystem>)' /home/acme/git/linux/tools/perf/util/c++/clang.cpp:94: undefined reference to `clang::vfs::InMemoryFileSystem::InMemoryFileSystem(bool)' /home/acme/git/linux/tools/perf/util/c++/clang.cpp:100: undefined reference to `clang::vfs::OverlayFileSystem::pushOverlay(llvm::IntrusiveRefCntPtr<clang::vfs::FileSystem>)' /home/acme/git/linux/tools/perf/util/c++/clang.cpp:101: undefined reference to `clang::vfs::InMemoryFileSystem::addFile(llvm::Twine const&, long, std::unique_ptr<llvm::MemoryBuffer, std::default_delete<llvm::MemoryBuffer> >)' /tmp/build/perf/libperf.a(libperf-in.o): In function `perf::getModuleFromSource(llvm::SmallVector<char const*, 16u>, llvm::StringRef)': /home/acme/git/linux/tools/perf/util/c++/clang.cpp:109: undefined reference to `clang::vfs::getRealFileSystem()' /tmp/build/perf/libperf.a(libperf-in.o): In function `clang::CompilerInvocation::~CompilerInvocation()': /usr/include/clang/Frontend/CompilerInvocation.h:102: undefined reference to `clang::CompilerInvocationBase::~CompilerInvocationBase()' /tmp/build/perf/libperf.a(libperf-in.o): In function `void __gnu_cxx::new_allocator<clang::PCHContainerOperations>::construct<clang::PCHContainerOperations>(clang::PCHContainerOperations*)': /usr/include/c++/6.2.1/ext/new_allocator.h:120: undefined reference to `clang::PCHContainerOperations::PCHContainerOperations()' collect2: error: ld returned 1 exit status Makefile.perf:491: recipe for target '/tmp/build/perf/perf' failed make[1]: *** [/tmp/build/perf/perf] Error 1 Makefile:108: recipe for target 'install-bin' failed make: *** [install-bin] Error 2 make: Leaving directory '/home/acme/git/linux/tools/perf' [acme@jouet linux]$
