Modern equivalent of --with-egl-window-system=rpi ?

[Michael Tyson]

It is:

./configure --build=arm-linux-gnueabihf --prefix=/usr --includedir=${prefix}/include --mandir=${prefix}/share/man --infodir=${prefix}/share/info --sysconfdir=/etc --localstatedir=/var --libexecdir=${prefix}/lib/gst-plugins-bad1.0 --srcdir=. --disable-maintainer-mode --disable-dependency-tracking --disable-silent-rules --libdir=${prefix}/lib/arm-linux-gnueabihf --disable-examples --enable-DEBUG --enable-debug --enable-experimental --with-package-name=GStreamer Bad Plugins (unknown Debian derivative) --with-package-origin=http://packages.qa.debian.org/gst-plugins-bad1.0 --disable-pvr --enable-gtk-doc

That’s with my NEED_GLES2 modification which, you’re right, should have been a —enable-gles2 flag.

Here’s config.log: http://cl.ly/0K1P0w1t0I2Y

Thank you!

Adding "NEED_GLES2=yes” to configure.ac:719 causes configure to disable GL instead ("Disabling Desktop GL support”), but unfortunately the build fails on target libgstgl_dispmanx_la-gstglwindow_dispmanx_egl.lo with the following: http://goo.gl/iQ5ngZ("error: conflicting types for ‘GLintptr’”, etc).
