Summary0005260: Can't play fullscreen on Mac OS X Lion (bug in outdated SDL)
DescriptionWhen you try to take DF fullscreen from the prompt, the following error appears:

Feb 18 10:12:05 smaug.local dwarfort.exe[2246] <Warning>: CGDisplayBaseAddress is obsolete and returning NULL for display 0x42801c0
Steps To Reproduce(1) Set init.txt to PROMPT mode for windows/fullscreen
(2) Start df
(3) Answer "YES" to the fullscreen prompt.
Additional InformationManager's note: Suggested fix: update SDL to SDL 1.2.15
1. Download SDL-1.2.15.dmg from [^] (under Mac OS X). Direct link as of May 2016: [^]
2. Open the downloaded .dmg file
3. Replace SDL.framework (possibly displayed as "SDL") in the libs folder in your DF folder with the downloaded version of SDL.framework
TagsFixed in 0.43.05?, SDL

Try changing the PRINT_MODE in init.txt (to STANDARD or whatever).

Does not help at all to change the PRINT_MODE to standard.

The only way i can play is windowed with massive resolution to come close to my screen size.

But making windowed mode exactly my screen sizes crashes the game.

I get an error every time about SDL using the QuickDraw library which is completely depreciated in Mac OS X Lion, it should be using QuartzCore.

This would explain earlier Macs being about to run the game properly, because QuickDraw has not been fully Depreciated on those machines.

I can verify that this can be fixed by using SDL 1.2.15. I was able to substitute the 1.2.15 SDL.framework by placing it into the <DF_ROOT>/libs/ directory in place of the old one, opening terminal to <DF_ROOT>/libs/SDL.framework/Versions/A/, and running `install_name_tool -id @executable_path/../Frameworks/SDL.framework/Versions/A/SDL SDL` After that, Dwarf Fortress could be run in fullscreen without crashing, or indeed without any issues at all.

If toady can compile the next DF release against SDL 1.2.15, that should fix the problem. In the mean time, enterprising users can apply the same fix I did (note that install_name_tool comes with the XCode command line tools package).

(Manager's note: The install_name_tool step may not be necessary.)

I can confirm that philomory's hack works. It would be great if SDL 1.2.15 was included in the next official MacOS build.

This bug still exists in v0.40.02 for OS 10.7.5.

Issue still exists with DF 0.40.15 and OS X 10.10 (Yosemite). The fix from philomory still works.

Could someone help me with philomory's trick?

I successfully switched the SDL.framework, put in the terminal line (which I assume had an extra "SDL" at the end), got this:

Usage: /Library/Developer/CommandLineTools/usr/bin/install_name_tool [-change old new] ... [-rpath old new] ... [-add_rpath new] ... [-delete_rpath old] ... [-id name] input

but the problem is still happening. Mar 9 19:08:30 Matthews-MacBook-Pro.local dwarfort.exe[23390] <Warning>: CGDisplayBaseAddress is obsolete and returning NULL for display 0x4280800

I am most likely making a stupid mistake right now as I am new to all of this stuff.

I think it should work without the install_name_tool step (i.e. just replacing SDL.framework should work). Can you provide the command you used?

Edit: There was not an extra "SDL" at the end of the command; it was intentional (but you don't need to run it, as far as I can tell).

I downloaded Dwarf Fortress 0.42.06 (most recent at time of writing) and the game would not even start unless I applied philomory's fix.

Mac OS X 10.11.3 "El Capitan".

Please update to the latest version of SDL (1.2.15, released in 2012!) when building the Mac version in the future.

May be fixed in 0.43.05, since Toady reports that he is using SDL 1.2.15 now.

This looks like it's working in 0.43.05 for me. Please PM me on the forums to reopen this report if not.
