[ft] Freetype cross-compilation issue - Inconsistent results

[Rasmus Kjeldsen]

Hi All

I have a program which uses Freetype (through libgd). When I run the program on my host computer (i386 Ubuntu) I get the desired result, but when cross-compiling it to ARM (an Gumstix Verdex) I get a slightly different result.

The program is listed below, attached is two png images, one from the i386 and one from the arm machine.

Note how the text is slightly distorted on the arm image.

I'm using libfreetype 2.3.5 on both machines, libgd 2.0.35 on the arm, libgd 2.0.34 on the i386 host.

Any suggestions?

Cheers
