Pull Request - Travis CI build

[Yashiroo]

Hello, I've just contributed to this project by adding a new feature that enables the export of specific flags. I've opened a pull request but the Travis CI build is not passing, for some reason (i think it's the 'release' part of the configuration). Could someone please let me know if you guys want to add my contribution, and if so what i should do to fix this build issue? Thanks
