| | \0 is really zero, so try replacing that with just 0. |

| Found out this Error is because of a bug in one of the GCC files.
I just removed the -Werror flag and it compiled fully after changing all "\0" with 0. | | Top |

| That flag just makes warnings become errors. They always were warnings, but with that flags it won’t let you compile them.
The idea behind that is the warnings are there for a reason, and you may find that even though it compiles you may have run time issues. |

| This is a confirmed bug of "snprintf" in GCC 7 and 8
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80924
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78969
I believe Its just the warning coming up is the bug but the code should still work | | Top |
