Indeed, several downstream projects don't follow ICU development and still use icu-config for library detection. ICU upstream doesn't force the pkg-config library detection either. That's why I still need to ship icu-config which is the barrier of co-installation of multi-arch packages. The way of dependency is intentional. Not all ICU dependent programs need icu-le-hb but all icu-le-hb dependent packages need ICU.
> Yes, you really need to fix the dependency cycle soon. I would like to. Of course, I can do an intermediate step to break the dependency cycle. But the best would be to drop icu-le-hb for being unmaintained and mainly unneeded. Only OpenTTD uses it and its maintainers are noted even via Debian[1] that icu-le-hb and its functionality is long deprecated. > In the mean time, we can perform the native build pass without > libicu-le-hb-dev.

Please consider applying the attached > patch. As noted above, it would break OpenTTD big when cross building. You need to manually bootstrap ICU as I had to with native builds. Yes, first build it without icu-le-hb and remove the layoutex library from the installation. Then build icu-le-hb with the new ICU and install it. Then you can build without disabling the layoutex library and be able to build OpenTTD as well. This I remove the patch tag. But if your intention is to cross-build ICU only and don't mind if OpenTTD is unbuildable, then add back the patch tag and I'll upload this change somewhen. Meanwhile, Matthijs can you tell us how the OpenTTD layout work goes? May you have any ETA from its upstream? It would be good to drop icu-le-hb very soon.
