MORIN Date: Sat, 19 Apr 2014 22:01:43 +0000 (+0200) Subject: package/mesa3d: always enable openGL X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=384d601d4ea2c41bb7928f756bfe88af4d38b38b;p=buildroot.git package/mesa3d: always enable openGL Currently, we only pass --enable-opengl is at least one DRI driver is enabled, since full OpenGL is only possible with a DRI driver (and the X.Org stack). Otherwise, we pass --disable-opengl on the assumption that OpenGL is not possible. But mesa3d's ./configure is a bit weird: enabling OpenGL-ES and diabling full OpenGL is an error (see autobuild failure below). It turns out that, if there is no DRI driver enabled, but --enable-opengl is passed, ./configure will behave properly wrt OpenGL-ES, and will not build the full OpenGL libgl. Thanks to Paul for explaining this. Fixes: http://autobuild.buildroot.net/results/61c/61c1c566dc0e829cb663ca30b1fd6cf9cc6cd931/ Signed-off-by: "Yann E.
