Yes, Debian allows you to install RPMs. You need the "alien" program to 
install it. If you haven't got alien, then do this first (as root):

apt-get install alien

aptitude install alien

apt-get is depreciated.

However, i've never used the RPMs on my debian systems when installing
eCos. The toolchain comes as tgz and i build the host tools from
sources. The only trick is you need to specify which version of tcl
and tk to use and you need to give the path to them when running the
configure script. This is talked about in the README file.

You might also want to try

aptitude install ecosconfig

and 

aptitude install ecos

I've never used these, so i've no idea how up to date they are.

[ECOS] context.S problem

[Wendell Liu]

 
Hello, Andrew and other eCos experts,

I just started using eCos with SH4 for my next project, and I try to build
eCos image. On my machine, I always encountered the following errors:

sh-elf-gcc -c -I/... src/hal_sh_arch_context.o
/cygdrive/c/cygwin/opt/ecos/ecos/packages/hal/sh/arch/current/src/context.S

/cygdrive/c/cygwin/opt/ecos/ecos/packages/hal/sh/arch/current/src/context.S:
Assembler messages:
/cygdrive/c/cygwin/opt/ecos/ecos/packages/hal/sh/arch/current/src/context.S:
257:
Error: Cannot represent relocation type BFD_RELOC_SH_IMM4BY4

I checked the ecos-discuss mailing list, and found Andrew ever answered the
assembler question, but I couldn't get the clue.

I used the following versions:
make -v
GNU  Make version 3.79.1

sh-elf-gcc -v
gcc version 3.2.1 (eCosCentric)

sh-elf-as -v
GNU assembler version 2.13.1 (sh-elf) using BFD version 2.13.1

Could Andrew or someone else please help me to get this out?

Highly appreciate your help.
Wendell

I don't see the correct compiler flags there. How are you trying to build 
eCos? Have you read the user manual?

Thanks, Jonathan.

I didn't put all the flags in the email. Yes, I read almost all the manuals
and the Anthony J. Massa's eCos book. The build should be quite straight
forward. My issue is probably related to my computer setting/environments
etc. Could you give me some hints here?

Thanks again,
Wendell

The line in question in context.S does not appear to have a relocation on 
it *unless* CYGARC_JMPBUF_SP has somehow not been defined. Check the 
contents of install/include/cyg/hal/sh_offsets.inc. And try a clean build 
from an empty tree.

The two SH header files:
...install\include\cyg\hal\sh4_offsets.inc
...install\include\cyg\hal\sh_offset.inc 

Both are empty, i.e. 0 size.

If I replaced these two empty files with pre-compiled files, then I can
build the image.

I don't know when to create these two SH header files? Could you instruct
here?

Appreciate your help,
Wendell

RE: [ECOS] Re: context.S problem

[Wendell Liu]

 
Hi Jonathan,

This is not context.S issue at all. It's reated to the fgrep.

In my environment, fgrep just contains:
!<syslink>grep

However, fgrep can not be executed as below:
$fgrep
/usr/bin/fgrep: 1: Syntax error: redirection unexpected.

If I just copy grep.exe to fgrep.exe, I can build my eCos image smoothly.

Does this mean that somehow I lost symlink here? Do you know how to fix it?

Many thanks,
Wendell

Did that fgrep come from cygwin? It might make some sense if it came from 
elsewhere. Is this a new cygwin install? It's possible they broke things :-|.

What do you have in the ethernet.tdf file? You need something like:

Yes there is, but i use only:

isn't it sufficient?

The documentation says that is sufficient, but it also lists the
disadvantages of not specifing which tap device and the MAC address.

Does the tap device appear in your ifconfig list?

Do you have the rawether program? Is it suid?
