GCC can't find Adress Sanitizer

[zharr]

Hey,
I've tried compiling my project with -fsanitize=address a few times now (tried across 14-16) but it never manages to find "/usr/local/lib/libasan_preinit.o" which it needs for linking.

Code: [Select]

gcc -print-search-dirsShows it is not looking in "/usr/local/lib", which I assume is why it doesn't work. A quick and dirty fix that does make it work:

Code: [Select]

sudo ln -s /usr/local/lib/libasan_preinit.o /usr/lib/Since this persisted across a few version without anybody else complaining it might not be super critical but perhaps it can get addressed in the next version. Until then, hopefully the people encountering that issue find this.
Thanks for your work on piCore!

gcc is built for /usr/local, so not sure why its not including that by default.  You can define your search paths with enviroment variables too.

17.x is already built, did you look at that?

I haven’t seen that error, but I’ve seen a similar error with libgomp - up until now I’ve been unable to fix it without resorting to a similar symlink.

Thanks, can confirm setting "LIBRARY_PATH=$LIBRARY_PATH:/usr/local/lib" also works.
Have not tried 17 yet, and likely won't for a bit. Fully switching versions is quite a lot of work, though ig I could try it out normally
