Mac 10.8 10.9: Java says it needs X11 on the machine - install XQuartz

Asked by slothbear

I'm totally new to Sikuli, so please excuse if this is a totally doofus question. When I try to run a script, I get the following message:
   To open "java," you need to install X11.

The docs are pretty thorough and mention other prerequisites, but I didn't notice X11. I've also searched and searched and didn't find anyone else mentioning this – or other questions about X11 here.

Perhaps my system is misconfigured and the X11 message is spurious?

I'm running Mac OS X 10.9.2.
I re-installed Java tonight, but... the file I downloaded and ran was called jre-7u55-macosx-x64.dmg, and when I check 'java -version', I see
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)

I'm not familiar with Java versioning, but '55' seems different than '45'. Perhaps the X11 message is happening because I've messed up my system.

If X11 is required, I can go with that. If X11 is not required – just let me know and I'll work on sorting out my installation somehow.

I got the same X11 message during the setup phase – when it tried to run a test I think. These lines at the bottom of the SetupLog seem to say it found my screen, which is 1440x900. These are the last lines in the log file.

And if X11 is required, are there any recommendations on which version to use? The message is offering to install Apple's X11, but I found an opinion that suggests XQuartz may be better:

I am not aware of this.
But a quick googling revealed, that this might be a case since X11 is no longer with OSX automatically since 10.8

But I will check that the next weeks.

Meanwhile you do no harm to your system installing XQuartz (http://xquartz.macosforge.org/landing/), which is the package supported and recommended by Apple itself.

Thanks for the quick help! Yes it is true that Apple stopped including X11 with Mac OS X.

I agree that it would do no harm to install XQuartz, but if X11 is a prerequisite for Sikuli, it would be helpful to list it as such.

Thanks again! I'm having a great time watching automation now. such great fun.
