Hi Martin,

Do you have the tarball ?

Hi Craig.

I am successfully using a cross-tool chain I compiled myself on OSX. It works for the TS7250 using the default 2.4.26 kernel.

I want to move to the new TS7500 as a platform, which has the 2.6.24 kernel. It is not possible to build the toolchain on OSX, because there is place where there are two files of the same name but differing in case. The workaround is to create a case-sensitive filesystem on a disk image and mount that. I can't be bothered to do that, so I use Ubuntu 8.04 in a Parallels Desktop virtual machine which allows me to use a prepackaged cross compiler.

I had some grief compiling it so it might be best if I upload a tar.gz to the files area of this group, if I can. It's 29MB.

I'll also put some sample Makefiles in as guidance.

I use these environment variables defined in .profile:
CROSSTOOL=/opt/crosstool/gcc-3.3.4-glibc-2.3.2/arm-unknown-linux-gnu
ARM=arm-unknown-linux-gnu

This means my makefile looks like this:

CC=$(CROSSTOOL)/$(ARM)/bin/gcc
NAME=victron

all: $(NAME)
$(CROSSTOOL)/$(ARM)/bin/strip $(NAME)
mv $(NAME) $(NAME).new

$(NAME): $(NAME).c

This creates the executable as a stripped file called in this case victron.new; just a local convention.

Do you want the crosstool.tar.gz file?
