Initial Mac OS X Support, X Improvements – SDK

Here is the first attempt at supporting Mac OS X. For now the interface & graphics driver run on X11. Support for a more native solution such as Carbon is planned for the future, but it is not a priority for the moment. This should allow Mac folks to give the Ecere SDK a try, and hopefully attract contributors who would like to improve Mac support.

There are a few glitches with Ecere on X on Mac. To get anywhere you will most likely need the server rather than the old XFree86. comes by default with Leopard, but for those still on Tiger, here is where you can obtain prebuilt binaries for it. Also take a look at this page. You will also need the same dependencies as for Ecere on Linux, such as libjpeg, libpng, freetype, fontconfig, etc., some of which might not be already installed on your system. Some other problems seem to be caused by the interaction with quartz-wm (another window manager might work better). For some reason, new windows always want to be positioned at the top-middle position of the desktop. I had to patch the X driver to get around this problem, but it still causes some annoying repositioning of the windows. Sadly, the overall performance especially with text seems a lot slower for me than on Linux/ 7.3. I am not sure what is making XRender so much slower on my Mac. On my system the IDE has a little trouble dialoguing with the installed GDB 6.1 which prevents the integrated debugger to function. It might work on a more recent version of GDB.

Please give me feedback on how Ecere on Mac works out for you in the comments.

A few important improvements were also made to the X driver. Windows can now be closed through the window manager. Repositioning windows from the Window manager doesn’t confuse their positions anymore. 15/16 bit displays are now supported.

I found that the Xrender API documentation is very difficult to find, and quite incomplete. Here is where the latest Xrender protocol is at and here is a copy of Xrender library API documentation. Trying to get 16 bit working, the XRenderFindFormat function was particularly difficult, but I learned that the count parameter which the above documentation isn’t so clear about had to be 0. The color masks should also not be shifted.
