when you compile a project created by project-creator under linux, you will get this error

Have you submitted a pull request or issue? I’m having the same issues on Linux Mint 16, gcc 4.8.1. Even after running the Linux dependency installation script.

Edit: Submitted an issue with a link to this thread. :slight_smile:

Hello guys,
I think I’ve found the same problem, but I solved it in the end.
I’m using Ubuntu 14.04, which libglfw2 was installed automatically.
So I uninstall it first, just typing “sudo apt-get purge libglfw2”
and then execute the script “cocos2d-x-3.3/tools/travis-scripts/install_glfw.sh” and after that, I can build my “hello project” properly.
Hope this idea can help you.
Love Linux, Love cocos

@ffpwserver Thanks! It is due to the original libglfw.
