According to HOWTO in the Doc directory for the Snapgear LITE you can build either 2.0 or 2.4 -- so I didn't try 2.6. >> the later failure which is caused by a non-existant directory >> path being passed to mkdep: >> >> -I /usr/local/lib/gcc/m68k-uclinux/4.1.1//include >> >> That's wront because my toolchain is not installed in >> /usr/local. I was unable to figure out where that path was coming from so as temporary work-around, I set up a symbolic link from /usr/local/lib/gcc/m68k-uclinux to the proper directory. After that I did get a successful build for the SnapGear Lite. It turns out that the SnapGear units I've got sitting around are Pros and not Lites, so I'll try building for the Pro... -- Grant _______________________________________________ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
