Thank you very much for the quick reponde. I tryied your suggestion and
I get this at compilation time:
make[1]: Entering directory
`/d/cygwin/home/portolan/testbenches/build/mingw_ecos/new_CR/tima_ft/current'
make[1]: *** No rule to make target `src/compile', needed by
`libtarget.a.stamp'. Stop.
what does it mean?
I think you typed the line incorrectly. Compare what you've done
with similar lines in other CDL files - you'll see how to fix it.
For example, look at the RedBoot CDL file .../redboot/current/cdl/redboot.cdl
Query reponse: it was just an old file I used when I started tapering
with interruptions,and no more used. I forgot to exclude it from the cdl.

I still cannot use the functions I added in a new package: I will try
to be as clear as possible:
-- when building eCos my .c file is compiled
-- when I compile e progrma linking on ecos libraries everything is
fine too (I can call my functions)
-- when executing I get error
If I debug with DDD I notice that the function defined in my packages
are empty! Looking up the souirce list I can find the .h, but not the
.c!! I think that is the problem, I charge only the prototype and not
the real functions...But where I am wrong? The file is compiled?
Maybe something amiss in the cdl file?
Please someone help me, I cannto really go any further by myself!!!

Ps: here is the cdl file for my package:
cdl_package CYGPKG_TIMA_FT {
display "Tima funtionalities"
description " Blah blah blah 1"
# ====================================================================
# OPTIONS
cdl_component CYGPKG_TIMA_FT {
display "Blah blah 2"
flavor bool
compile rollback.c intr_rollback.S
default_value 1
requires CYGPKG_LIBC_SETJMP
description " Blah blah blah 2.1"
cdl_option CYGPKG_TIMA_FT_TRACE {
display "Enables Trace assertions"
default_value 0
description "
Blah blah 3"
}
}
}
And here how I call it up from ecos.db
package CYGPKG_TIMA_FT {
alias { "blah blah 0" tima_ft rollback }
directory tima_ft
script tima_ft.cdl
description "Blah blah 0.1"
}
Are your functions ending up in the final eCos application?
Do you have an applications that calls [at least one] directly?
If not, the linker may be throwing them out.
Try changing your "compile" directive to look like this:
compile -library=libextras.a rollback.c intr_rollback.S
Then
ecosconfig tree
make clean; make
Query: what's up with the "intr_rollback.S" file? eCos is designed
such that it's *very* rare to ever need to write anything in assembly.
