Then I guess its the scratchbox-toolchain-arm-linux-cs2010q1-202-1.0.17-2-i386.tar.gz the toolchain I will need..? where can I read info about the specific toolchain? > > > what is the soft/hard distinction ?? >> > > The soft/hard disctinction is for softfp/hardfp.

Which command did you use to > install the c-library? I used sb-menu to create test targets. Navigating through 'new target' creation, I chose a toolchain (f.e. scratchbox-toolchain-arm-linux-cs2010q1-202-1.0.17-2-i386.tar.g), then i chose devkits (f.e. qemu, perl and debian-* ) and then it would ask me whether to install a rootstrap -to which i answered no- and whether to install files - to which i answered yes. Next screen would take me to choose among options : C-library, C-runtime. gdb, xtrace and few other options. I chose all of them and next thing that appeared was a msg stating that installation of C-library failed on target <target_name>. > > > Finally, i am fuzzy about the qemu-arm and qemu-armeb cpu-transparency >> methods... >> > > The latter is for big endian architectures. > > Regards, > > Jussi > ______________________________**_________________ > Scratchbox-users mailing list > Scratchbox-users@lists.**scratchbox.org<Scratchbox-users@lists.scratchbox.org> > http://lists.scratchbox.org/**cgi-bin/mailman/listinfo/**scratchbox-users<http://lists.scratchbox.org/cgi-bin/mailman/listinfo/scratchbox-users> >
