[llvm-dev] why there is no libclang_rt.asan-x86_64-android.so
Hi all,
I want to do fuzzing test on Intel x86_64 platform, however I
cannot find the shared library for libclang_rt.asan-x86_64-android.so, can
anyone tell me where I can find this library?
Best Regards

Compiler-rt libraries for android are not built automatically because they need a target toolchain and a sysroot. The usual approach is 1. Build standalone ndk toolchain 2. Configure a build tree for compiler-rt with freshly built clang as the compiler, -B and --sysroot in CMAKE_C_FLAGS and CMAKE_CXX_FLAGS pointing to the ndk toolchain. Optionally, -DCOMPILER_RT_OUTPUT_DIR=$LLVMBIN/../lib/clang/5.0.0 would put the new library directly where clang can find it. 3. ninja asan in the compiler-rt tree Having said that, this configuration (x86_64 android) is completely untested, but I've just checked that it at least builds.
