I don't think that this bug has to be fixed for bullseye. There are around 800 other FTCBFS patches filed in the bts. It seems very unlikely that we even fix half of them in time for bullseye and this one is in no way special. > I'm a bit confused about your proposed change to krb5-config. > People search for krb5-config by that name not with a multiarch tripple. That is correct. My proposed change does not change the name of krb5-config. Doing so would be an option of autoconf users though. Like pkg-config, krb5-config could provide an additional, triplet-prefixed version that would automatically be discovered by consumers using AC_PATH_TOOL. > If that became multi-arch dependent, how would you install more than > one set of krb5 libs at the same time? That's precisely the tradeoff: You cannot. Now the question is whether that is a reasonable tradeoff. There are two features that are in conflict here: * krb5-config just works without exporting CC. * You can coinstall krb5-multidev for multiple architectures. While it is certainly nice to be able to coinstall development packages for multiple architectures, it is more of a convenience feature than an enablement feature. Much of the time, you only need the -dev package for the host architecture. Exceptions to this rule include zlib1g-dev, but that is a little more central. For instance, libgpg-error-dev is not M-A:same and thus far, this hasn't been a problem to cross building. On the other hand, teaching each and every consumer to export CC in order to use krb5-config is quite some work and not the "it just works" experience we are aiming for. It's not as clear (to me), which way is best here. That's why my patch uses the simple an non-intrusive way. But long term, the option of fixing this in krb5-config may be better (or not). For that reason, I attempted to sketch all possible solutions. I hope I could draw a clearer picture now. Helmut
