Compiler flags and so on are mainly handled by rpmbuild based on the macros for the architecture it's building on. So it's not like patching thousands of packages. > We could branch out a cortex or a v7 release, but that is more > logistic issues, and honestly by dropping arm5tel support.

I am very interested in running Fedora on armv5tel as we can today. > Tablets, laptops, embedded servers would be more realistic, and There is a quite wide spread of arm hardware about, it is not going to be the case that suddenly everything is Cortex. For example these last days I have been using Arm Fedora on NXP LPC3250 which is a new, cheap chip based on the ARM926EJ core which is armv5; Fedora is working great on SD Card. The last thing I worked on uses Fedora on an iMX31 CPU which is ARM1136 / armv6. If it makes a big difference to build for high end cortex specifically, then I hope we're able to keep armv5 while the chips are still current and being designed into things along the lines of i386 / x86_64. > As far as actually moving forward... > > If it is possible to cross-compile RPMS, and get sane results, it I think trying to make Fedora build cross is a whole other issue. Building stuff cross is a trickier business than you might think. Many packages with recent autotools can build cross OK, plus or minus some magic needed to work with rpmbuild like that, but there is no point doing all that work if there are fast ARM high-end machines available that can build them native. Surely it's clear that high end arm machines are clearly going to approach x86 kinds of speed anyway in the next years reducing any pay back from the effort of going cross. -Andy _______________________________________________ arm mailing list arm@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/arm
