Spec files need to be written appropriately for cross-compilation to be supported as you need to override the compiler used (and possibly other tools) and configure scripts need to be passed a host system name. Also depending on the cluefulness of a given maintainer/team, packages might be easy or difficult to cross-compile -- heavy patching is required in some cases. For the way I am using RPM to cross-compile you might visit my FTP site at 'ftp://ftp.ds2.pg.gda.pl/pub/macro/' (mirrored at 'ftp://ftp.rfc822.org/pub/mirror/ftp.ds2.pg.gda.pl/pub/macro' -- thanks, Flo). There are source and binary packages as well as configuration files I use. Read the READMEs and look at a few spec files and everything should be clear. Many of the *.mipsel.rpm packages available there were cross-built -- you may verify it with `rpm -qip': "macro" is my i386-linux system, while "3maxp" is my mipsel-linux one (still no i386-linux cross-compiler on my mipsel-linux system, sigh... :-( ). You need to build cross-binutils, cross-gcc and cross-glibc to start. I've already written and sent a detailed description on cross-gcc bootstrapping here. I'm not sure if the list is archived, or not. If not, I may dig through my mail archives and send it again. If you have any specific questions, don't hesitate to ask me. Maciej -- + Maciej W.
