OpenTTD 1.0 compiles and runs fine on armv7a (IGEPv2), so please add ~arm keyword. Thanks in advance! Reproducible: Always
I can second that. games-simulation/openttd-1.0.1 (bumped myself) built native on my N900, and games-simulation/openttd-1.0.0 built cross and played. CHOST=armv7a-unknown-linux-gnueabi The following optional dependencies of OpenTTD also built fine for me native on N900: games-misc/opengfx-0.2.4 games-misc/openmsx-0.2.1 games-misc/opensfx-0.2.3 games-util/catcodec-1.0.0 games-util/grfcodec-0_pre2306 games-util/nforenum-0_pre2309
~arm keywords added, thanks for the report.
