Allow for X11-less egl builds on linux #80
Conversation
We might be cross-compiling and hence host might be != target. Signed-off-by: Gustavo Zacarias <gustavo@zacarias.com.ar>
Since libgtk3 uses libepoxy and can be built for wayland alone without X11 support it doesn't make sense to force OpenGL support and a full X11 stack. Signed-off-by: Gustavo Zacarias <gustavo@zacarias.com.ar>
When building mesa egl without x11 and gles2 the headers need a MESA_EGL_NO_X11_HEADERS define, so put them in epoxy.pc as well since otherwise builds will fail. Signed-off-by: Gustavo Zacarias <gustavo@zacarias.com.ar>

I think pull request #52 handles this a bit cleaner. Is there something about that change that doesn't work well for you. |

You still need gustavoz@68e5f15 since otherwise using non-glx mesa with libepoxy will fail to build properly (or rather libgtk3 with libepoxy in that scenario), like so: .../sysroot/usr/include/EGL/eglplatform.h:119:22: fatal error: X11/Xlib.h: No such file or directory Another matter would be to build egl-less glx libepoxy, but that wasn't addressed by me either. |

Any news on these? |

I've already landed all the required patches in buildroot to make this possible, take a look at https://git.busybox.net/buildroot/tree/package/libepoxy |

There was a problem hiding this comment.
No need for that, PKG_CHECK_MODULES does it already.
This patch series allows a cross-compiled EGL X11-less build for linux.
It makes sense for embedded targets where you don't want to pull in a big chunk of X11 stack to build gtk3 with wayland for example (via mesa EGL).
