( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/492079 ) Change subject: From 2.8 onwards, ASAN not working for libganesha_nfsd ...................................................................... From 2.8 onwards, ASAN not working for libganesha_nfsd Currently getting this warning when I enabled address sanitizer: CMake Warning at cmake/modules/sanitize-helpers.cmake:161 (message): AddressSanitizer disabled for target ganesha_nfsd because there is no sanitizer available for target sources. Call Stack (most recent call first): cmake/modules/FindASan.cmake:58 (sanitizer_add_flags) The reason is because the library libganesha_nfsd is made up entirely of object libraries without any source files of its own and hence the cmake script sanitizer_add_flags rejects enabling sanitizer for it. Current patch removes creating of FsalCore as Object library and instead directly add the c files as sources of target ganesha_nfsd. This is inline to what is suggessted in the cmake documentation: "Some native build systems (such as Xcode) may not like targets that have only object files, so consider adding at least one real source file to any target that references $<TARGET_OBJECTS:objlib>." https://cmake.org/cmake/help/v3.12/command/add_library.html The other change in this patch is that when SANITIZE_ADDRESS is enabled we should not use --no-undefined as mentioned in the ASAN docs: Q: When I link my shared library with -fsanitize=address, it fails due to some undefined ASan symbols (e.g. asan_init_v4)? A: Most probably you link with -Wl,-z,defs or -Wl,--no-undefined. These flags don't work with ASan unless you also use -shared-libasan (which is the default mode for GCC, but not for Clang). https://github.com/google/sanitizers/wiki/AddressSanitizer Signed-off-by: ashish.sangwan <ashishsangwan2(a)gmail.com&gt; Change-Id: Ibaf837804eed595eaa990b40b1ea5e11a229d571 --- M src/MainNFSD/CMakeLists.txt 1 file changed, 9 insertions(+), 8 deletions(-) git pull ssh://review.gerrithub.io:29418/ffilz/nfs-ganesha refs/changes/79/492079/1 -- To view, visit https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/492079 To unsubscribe, or for help writing mail filters, visit https://review.gerrithub.io/settings Gerrit-Project: ffilz/nfs-ganesha Gerrit-Branch: next Gerrit-Change-Id: Ibaf837804eed595eaa990b40b1ea5e11a229d571 Gerrit-Change-Number: 492079 Gerrit-PatchSet: 1 Gerrit-Owner: Ashish Sangwan <ashishsangwan2(a)gmail.com&gt; Gerrit-MessageType: newchange
