Well, I'd estimate 90% of all lib* packages do work OTB. It's the packages' authors who ship broken configurations, because they hard-code stupid things like run-time checks or hard-coding compiler/system features (byte-order, type-sizes etc.). > > Few packages do support mixed native/cross compilation and even less do > > support multi-target configurations. > > > > > Packages in _general_ won't cross-compile. > > Yes, because many packagers don't test it and because rpm doesn't > > support it. > > I've spent a lot of time attempting to cross-build the distribution. > RPM actually handles it just fine -- the problems were mostly caused by > the (possibly incorrect) use of autotools in the package itself. Well, this is NOT my experience. RPM doesn't even get the target/host/build-tuple right for native noarch building. Building cross-compilers (Note: These are native apps!) is PITA, because RPM doesn't handle foreign binaries correctly (stripping, debug info etc. all are treated as <native>-elf). Cross building (rpmbuild --target= ...) isn't even close to be be functional, because rpm screws up various target/host/build platforms setting (e.g. %rpmopt), and doesn't properly distinguish between target/host/build and contain many hard-coded redhat specifics (We are cross building cross-toolchain rpms to mingw, cygwin and solaris). > I agree, however, that there is nothing _fundamentally_ evil about > autotools.
