[ECOS] target.ld error

[ECOS] target.ld error

[ANILA SOOMRO]

I am using the eCos user guide to compile sample program hello.c but I get this error: cannot open linker script file target.ld: No such file or directory
although target.ld exists.
I am using cygwin bash on WinXp, can anyone help? I am new to Cygwin and eCos.
 
Thanks in advance.

Hello,

I am not very experienced with eCos, I am also almost new to it. But I
think I can help you. (such problem are not far for me) It is maybe
just a problem of path.
What is you target platform ?
Can you post us the makefile you use or the command you type and the
complier/linker output ?

Antoine

Re: [ECOS] target.ld error

[Alexandre]

I had the same problem actually ^^

Seems like cygwin has got problem registering your virtually mounted
"c" to reach your target.ld.
Try to check if it works with the target.ld in the same directory
(well it should undoubtly but that may give you your first glimpse at
ecos ^^). Then you'll have to figure out how to make cygwin now
exactly where your c (or d or e or f ...) drive is actually located.

I never actually managed to compile from the cygwin bash but it works
real fine for me when i do so in the windows command prompt, you may
try that as well and see how the ecos install directory is inputed in
your makefile.

Good luck !

RE: [ECOS] target.ld error

[ANILA SOOMRO]

It helped. Thanks.

I was building the kernel library with the right compiler but the problem was with my path. After adding the path to XP settings, everything started working.

However when I run the program I get the following instead of the program output:

Starting program: /ecos-c/ecos-work/PPC_install/a.out
core_find_mapping() - access to unmaped address, attach a default map to handle
this - addr=0xf000101a nr_bytes=0x1 processor=0xc871c0 cia=0x4514

I don't know how to get around this. Also, let me tell you when I use the config tool to build the library for PowerPC simulator target, I get certain conflicts. I just continue building. Is the above error due to the conflicts?

Thanks
dranne

> I choose the PowerPC simulator target and build it.

Did you build your kernel library with the PowerPC compiler or your
native compiler (gcc) ?  What's the value of
CYGBLD_GLOBAL_COMMAND_PREFIX in your kernel configuration?

If you don't know how to find the value of CYGBLD_GLOBAL_COMMAND_PREFIX:
1.) Select Edit -> Find... in the ConfigTool.  A find dialog box should pop up.
2.) Set the "Search In" field to "Macro Names"
3.) Search for CYGBLD_GLOBAL_COMMAND_PREFIX

It should be "powerpc-eabi-".  If it is, then you've been compiling
with the powerpc-eabi-gcc compiler that's on your Windows machine.
That's a good thing!

This means that either you don't have have the powerpc-eabi-gcc
compiler, or (more likely) that the command's path is not in your PATH
environment variable.

Usually the eCos cross compilers reside in C:\cygwin\opt\gnutools.  My
powerpc-eabi-gcc resides in:

C:\cygwin\opt\gnutools\powerpc-eabi\bin\powerpc-eabi-gcc

Make sure to use a cygwin formatted path (i.e. /cygdrive/c/...).

Hope this helps,
Mike

RE: [ECOS] target.ld error

[ANILA SOOMRO]

Hello

Unfortunately nothing seems to solve my problem.
Let me tell you exactly what I am doing.
As specified in the eCos user guide, I am using the ConfigTool for Windows.
I choose the PowerPC simulator target and build it.
My installation or build directory is c:\eCos-Work\PPC_install.
After doing this and following the user guide, I try to compile the hello.c example.
When I use the powerpc-eabi-gcc command, I get this error: bash: powerpc-eabi-gcc: command not found.
I don't know how to resolve this error. So I just try gcc, it works but gives the target.ld error as mentioned in my earlier emails.
I don't know if I am following the right procedure, all I want is to run the example programs on the PowerPC simulator using eCos.
Can anyone of you help me and tell me how to proceed. How to edit the makefile, etc. Am I doing the right stuff as I am absolutely new to eCos.


Thanks in anticipation.
dranne

Re: [ECOS] target.ld error

[Antoine Zen-Ruffinen]

The error come probably from your BASE_DIR variable. As cygwin emulate
a UNIX system, you should use the UNIX file path, not windows. I think
you set BASE_DIR as somting like
c:\path_to_my_workspace\some_other_dir\, no ?
Then you should set it to /cygdrive/c/path_to_my_workspace/some_other_dir/.
I develop under linux, so I can not be sure about cygwin config, but I
think it can be that.

Hope it help.

Re: [ECOS] target.ld error

[Antoine Zen-Ruffinen]

First, as somebody told me yesterday, it is important to reply also to
the mailing list, not only me. Some others will be maybe interested by
your issue.
With this makefile, does the error is just linking or does is not compile also ?

 I am attaching the makefile as well. Its the makefile present within
the examples directory.
I have edited it and the install directory is PowerPCSimulated_install.
