undefined reference to `stpcpy' problem during compilation #16
Description
Thanks for providing such cool tutorial! However, I encounter a problem in linking process. It says undefined reference to stpcpy. Then, I search stpcpy in the android source code, I did not see any definition. I have been stuck for the whole day, could you give some hints if possible?
