About the Libraries

In IDE for GR, in order to reduce the compilation time, most libraries archive and use compiled objects, and their sources are deleted.

The archive file uses gr_common.a generated by the build of the web compiler, but when changing the library, it is recommended to use an IDE that allows project management such as e2 studio.
