Hello list, I was getting the following error message after building with CFLAGS='-fsanitize=address -static-libasan' LDFLAGS=-static-libasan and trying to run the generated executable. ==5331==Your application is linked against incompatible ASan runtimes. Please note that the project also contains a shared library, which libtool was always linking while ignoring the "-static-libasan" flag. So the library was linking to "libasan.so" while the binaries were linked with the static runtime. The attached patch on the generated libtool script solved the issue to me. Feel free to use it upstream, if it makes sense. Thanks, Dimitris _______________________________________________ https://lists.gnu.org/mailman/listinfo/libtool
