eCos and GCC 4.1.0

[Marco Aurélio da Cruz]

Hi.
I've downloaded the ecos-trunk-20060319 snapshot from eCoscentric and
tried to compile it on arm-elf-gcc 4.1.0.

I got the errors below:

.../include/cyg/kernel/sched.hxx:181: error: extra qualification
'Cyg_Scheduler::' on member 'thread_entry'
.../include/cyg/kernel/thread.hxx:315: error: extra qualification
'Cyg_Thread::' on member 'reinitialize'

I edited the files in /packages/kernel/current/include and removed the
qualifiers. So it compiled OK.

sched.hxx

from:
/// perform thread startup housekeeping/
void Cyg_Scheduler::thread_entry( Cyg_Thread *thread );

to:
/// perform thread startup housekeeping/
void thread_entry( Cyg_Thread *thread );
 

thread.hxx

from:
/// Re-initialize the thread back to it's initial state./
void Cyg_Thread::reinitialize();

to:
/// Re-initialize the thread back to it's initial state./
void reinitialize();


Regards

Marco Cruz

Please could you produce a proper patch, with ChangeLog entries.

I've read some messages about doing this but I'm not aware how to...

I edited my local /packages/kernel/current/include files, changed the  
/packages/kernel/current/ChangLog but I'm not able to generate the diff
file. I'm so newbie with CVS and patches...

Go to the "ecos" directory (where the packages is located).

and do:

cvs -d :pserver:anoncvs@...:/cvs/ecos diff -u packages >
packages.01.diff

You then get all modifications in the packages.01.diff

Such an old version of eCos, version 2.0, will not work with 4.1.1. See

The warnings about boilerplate C++ options being ignored in C is normal. But
the single actual error at the end of that is the result of a nonstandard
(and pointless) bit of syntax that the earlier compilers were willing to
forgive, but eventually was ruled illegal in the more recent compiler. It
was fixed in the latest rev of the eCos source code in the obvious manner.

This is a toolchain/debugger problem, not an eCos problem. Try looking
on the gcc mailling lists and talk to the tech support for axd.

And what exactly does the debugger say?

What does Wind River say?

Like i said, this is a tool chain problem, not eCos.
