Hi Eddie,
I'm picking up on this discussion because it seems related to a
problem I'm having.
First can you explain the difference between ftp.embedded and
oz.embedded ? At first view they seem identical but here you refer to
files on both implying a difference.
I'm using the "full debian" image booted via nfs. Using this setup I
am able compile my own .c file example based on Jim's adc_logger and
it works.
My current problem is I'm trying to build simple module to interface
to /proc. A trivial example to get this set up.
Now I have installed the ts11 kernel source tarball provided but any
attempt to call make within the tree spews a lot of errors like this:
:linux# make menuconfig
/bin/sh: line 1: cd: /usr/src/linux-2.4.26-ts11/../../tools/crosstool/
arm-9tdmi-linux-gnu/gcc-3.3.4-glibc-2.3.2/bin/: No such file or
directory
/bin/sh: line 1: cd: /usr/src/linux-2.4.26-ts11/../../tools/crosstool/
arm-9tdmi-linux-gnu/gcc-3.3.4-glibc-2.3.2/bin/: No such file or
directory
/bin/sh: line 1: cd: /usr/src/linux-2.4.26-ts11/../../tools/crosstool/
arm-9tdmi-linux-gnu/gcc-3.3.4-glibc-2.3.2/bin/: No such file or
directory
/bin/sh: line 1: cd: /usr/src/linux-2.4.26-ts11/../../tools/crosstool/
arm-9tdmi-linux-gnu/gcc-3.3.4-glibc-2.3.2/bin/: No such file or
directory
/bin/sh: line 1: cd: /usr/src/linux-2.4.26-ts11/../../tools/crosstool/
arm-9tdmi-linux-gnu/gcc-3.3.4-glibc-2.3.2/bin/: No such file or
directory
This would seem to be a relic of the development system from which
the kernel tree was pulled.
You asked me to signal this sort of problem in another thread.
I can understand that the source tree is supplied separately due to
it's size but it does not seem to correspond to the debian tarball.
These images would be much more useful if self consistent (eg the
missing modules directory) and worked together.
Maybe I have pulled incompatible tarballs from different parts of the
server.
If I should get a different src tarball could you please give a link?
Otherwise indicate how to get make to use the working debain
toolchange not a non-existant cross-compiler.
Many thanks.
Jacques.
