Error with Xelatex when building DemoSensors

[BusFactor1Inc]

When testing, I can build Calculator fine, but when trying to build DemoSensors I get the following errors:

bash-3.2$ ./configure DemoSensors ios

I've install xelatex using macPorts on Mojave.

Removing xelatex packages allows the use of libgd, and the error does not occur.

The problem is still interesting as it seems to be either an incomplete xelatex or a package conflict of some sort in your installation. If you don't need latex support for anything else, this should work well though.

[BusFactor1Inc]

What else would latex support be needed for other than rendering strings?

[mgorges]

For lambdanative that is correct, but I for example need it to typeset papers?

[BusFactor1Inc]

Oh, haha. I thought it might be used for other things in LN. Thanks for the clarification.

Calculator did build using latex for some reason using the install, but not the DemoSensors. I didn't notice a difference in image quality between the latex and libgd renderings, so I'll stick with libgd since it works :)

[mgorges]

I find this odd, as why would xelatex work in one case but not the other? DemoSensors builds these FONTS: cmss.ttf 7 12,30 ascii and uses cmss.ttf also for its strings Calculator uses these FONTS DejaVuSans.ttf ascii7.set 32,24,14 calc and has no STRINGS.

--> It seems to be related to rendering the exit string, which is cmss.ttf 24 "Exit" exit
