However, in the cases covered by this patch, it's always a value that fits in int being stored temporarily as a pointer and then converted back later, which is safe. Casting through the pointer-sized integer type intptr_t convinces the compiler that this is OK.

* Clear header file namespace separation (<X11/...> vs. <nx-X11/...>).Mike Gabriel2015-12-281-3/+3
| | | | | | | | | | | | | | | | | | | | In the process of building nxagent against more and more system-wide installed X.org libraries, we come to the limit of including structs from this (bundled nx-X11) and that (system-wide X.Org) library. This commit introduces a clear namespace separation of headers provided by nx-X11 and headers provided by X.Org. This approach is only temporary as we want to drop all nx-X11 bundled libraries from nx-libs. However, for a while we need to make this separation clear and also ship some reduced fake X.Org headers that avoid pulling in libX* and libNX_X* symbols at the same time. This patch has been tested on Debian jessie and unstable and requires no overall testing on various distros and distro versions, as we finally will drop all libNX_X* libraries and build against X.org's client libs. For now, this hack eases our development / cleanup process.

| | | | | | | | | | | | The client-side library libNX_GL.{a,so} is not built when building nx-libs. However, nx-X11/lib/GL/** ships several imake include files (Imakefile.inc) that are also used in nx-X11/programs/Xserver/GL/**. These files have been moved from the nx-X11/lib/GL/ code subtree to the nx-X11/programs/Xserver/GL/. Furthermore, we don't provide module builds of the GL extension anymore, as that feature is neither used in nx-libs.
