The toolchain you've selected above actually is softfloat and EABI. You don't have to change anything, just do the steps you've mentioned above and 'ptxdist go'. > Unfortunately there is an error about mismatch in the linux-kernel > headers. Please send the exact error message (if too long, please off-list, to me and "Marc Kleine-Budde <m.kleine-budde@xxxxxxxxxxxxxx>"). > My Host PC has linux-kernel of 2.6.24 and not 2.6.27. That's no problem; the toolchain you are trying to build is based on the 2.6.27 sanitized kernel headers. It's usually no problem at all using such a toolchain on a variety of other kernel versions. > My target is working under 2.6.26.8-rt14 kernel.

You may want to check that we have an update for 1.99.3 here: http://www.pengutronix.de/oselas/toolchain/download/OSELAS.Toolchain-1.99.3.1.tar.bz2 There has been a build error on some distros and it might happen that you are seeing exactly this issue. rsc -- Pengutronix e.K. | | Industrial Linux Solutions | http://www.pengutronix.de/ | Peiner Str. 6-8, 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 | -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
