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
