Make sure to use latest version of C4droid installed from Google Play.
Dear pirates! I think that it will be fair to don't write your reviews here. If app doesn't work/install it's a problem of hackers, not my app.
Anyway if app doesn't work, write your review to C4droid, not to plugin, pirates can't do that, so their reviews here will be ignored =)
It's a plugin for c4droid, that allows it to compile C and C++ source code using GCC.
It contains gcc 4.7.1 with Bionic (Android libc). Source code hadn't been modified, so you can compile it yourself, if you want.
