Created attachment 625882 [details, diff] libnipper-format-security.patch I couldn't recreate this when adding CFLAGS="-O2 -pipe -march=native -falign-functions=32:25:16 -fno-common -Werror=format-security -Wformat", so I don't know if my toolchain would need compiling differently, but I think I've understood the error anyway. Essentially there's a variable that could be changed which doesn't contain a format argument. Since in the code the value doesn't ever actually change, I've made the entire thing a fixed const, which hopefully then will be accepted by the compiler. Is there any way to easily test this patch in your build system, or let me know what changes I'd need to make to my system to be able to reproduce the error?
