Re: [uClinux-dev] elf2flt error with ARM Cortex-R4 toolchain
Hello Pankaj
I've successfully built a toolchain for an arm926ejs that allow me to build an
simple c hello world (i haven't tested multithread, c++, or complex project
with lot of dependancies, ...)
I used the git://sources.blackfin.uclinux.org/git/users/vapier/elf2flt.git
sources with the attached patch.
The script used for compiling the toolchain is
https://gitorious.org/bif/bif/blobs/master/framework/packages/toolchain-uclinux_uclibc/toolchain-uclinux_uclibc.sh
It's a personal job that should not be taken as a reference... and perhaps you
could also see the sources of busybox, crosstools-ng or openembedded ...
Regards.
Paul.
