[ECOS] Questions about CodeSourcery g++ Lite tool chain and eCos

[Eigil Krogh Sørensen]

Hi


. Is it possible to use CodeSourcery g++ Lite toolchain for eCos? I would like to use that because the compiler is newer, gcc-4.5.1, than the gnutools for ARM, that comes with eCos, gcc-4.3. gcc-4.5. can make code ARM11 and Cortex-R/A.

. Can CodeSourcery g++ Lite toolchain be used together with eCos config tool in Windows?

. Which version of the CodeSourcery g++ Lite toolchain should be used with eCos?

I'm using latest CodeSourcery toolchain for eCos (the arm gcc). If you want to
use cygwin you need make version 3.80, because the latest make doesn't work
correctly with non-cygwin paths and a correctly set CYGPATH variable. Build
directly in ecos config tool does not work, but creating a config and running
make in the *_build dir does.

I hope this helps you.

Bye...

Hi again Stefan


Which version of the CodeSourcery tool chain do you use. I have "arm-none-eabi". When I use that chain to compile eCos + app. I have the problem, that e.g. printf doesn't call the eCos function and thus nothing is printed.

Did you build the libraries youself?

I use arm-none-eabi and I like with: "-Ttarget.ld -nostdlib
-L<path>/ecos_install/lib"

Which arm cpu do you use?

I have succesfully used Sourcery G++ Personal to compile and link eCos 
in Windows. The graphical config tool works. I assume the latest version 
of SG++ Lite also works, but you'll have to test this.

It is a bit of a hassle, though.

1. SG++ is a native Windows program, meaning it expects Windows paths. 
Fortunately, it also supports CygWin paths. To enable this, the 
"cygpath" utility (installed with CygWin) must be made available:

1.1 Append your CygWin "/bin" directory to Windows path (right-click on 
My Computer, select "Properites", "Advanced", "Environment variables").

e.g. PATH="other stuff;C:\cygwin\bin"

1.2 Add a Windows system variable named "CYGPATH". Set it's value to 
"cygpath".

1.3 Start a new CygWin termial, verify that Bash shell can see both 
changes you made.

2. You need to add SG++ system headers to eCos. Before you do this the 
project should be cleaned.

In eCos configuration tool, under "Configuration", "Global build 
options", "Global compiler flags" following options should be added:

-isystem /cygdrive/c/Program\ Files/CodeSourcery/Sourcery\ G++\ 
Lite\lib/gcc/m68k-elf/4.3.3/include
-isystem /cygdrive/c/Program\ Files/CodeSourcery/Sourcery\ G++\ 
Lite\lib/gcc/m68k-elf/4.3.3/include-fixed

This assumes SG++ is installed to "C:\Program 
Files\CodeSourcery\Sourcery G++ Lite" and the GCC version is 4.3.3. 
Update this to match your setup.

3. Then ask the linker to not use it's standard library. Click on 
"Global linker flags". Add flag "-nostdlib".

Now save the configuration and select "Build", "Generate build tree".

4. Do not start the build from within configtool because it will not 
pass environment variables to compiler.

Instead, start a CygWin terminal, navigate to your eCos build directory, 
cross your fingers and type "make -j4".

I may have forgotten some details, but this should be the bulk of it.

Oh, and replace the "m68k-elf" with your architecture.
