如何在Android NDK GCC上使用AddressSanitizer？

Question

I want use AddressSanitizer to check memory problems in Android Native C++ Code compile with GCC 4.9.

so, I set

SET (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS}  -g1 -fsanitize=address -fno-omit-frame-pointer")
SET (CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -g1 -fsanitize=address -fno-omit-frame-pointer")
SET (CMAKE_SHARED_LINKER_FLAGS "${CMAKE_SHARED_LINKER_FLAGS} -fsanitize=address -static-libasan")

in my CMakeLists.txt file.

but I got an error:

ld.exe: error: cannot find -lasan",i find in NDK directory,i do not find libasan.so

Is NDK GCC different from NDK Clang? in NDK,just Clan Support AddressSanitizer?

Answer 1

You can't use ASAN with GCC in the NDK. Those libraries were never shipped. ASAN is supported with Clang, and GCC is not supported at all in current NDKs.

Is NDK GCC different from NDK Clang?

In the same way that non-NDK GCC is different from non-NDK Clang, yes. They're different compilers.
