From: Emil Velikov Date: Mon, 11 May 2015 22:43:48 +0000 (+0100) Subject: egl/main: expose only core EGL functions statically X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e3cc5ad49d2f3f08c29d0b64d1c0c52560789d93;p=mesa.git egl/main: expose only core EGL functions statically The EGL 1.3, 1.4 and 1.5 spec (as quoted below) explicitly mentions that providing static symbols for functions provided by EGL extensions is not portable. Considering that relatively recently we've seen a non-mesa desktop EGL implementation, the fact that we opt for such behaviour has gone unnoticed. From the EGL 1.5 specification: For functions that are queryable with eglGetProcAddress, implementations may choose to also export those functions statically from the object libraries implementing those functions. However, portable clients cannot rely on this behavior. To encourage devs against writing such non-portable code, let's hide the symbols similar to the official binary driver from NVIDIA. v2: Quote the EGL 1.5 spec, as suggested by Chad.
