[ECOS] math and stdlib problem problems which I found

Hi all,
 
    After I update the eCos from cvs and Alex 
recommand I could build the I386 PC target. At this time, I could test and 
download my sample program to target PC, and run it. But now I also have some 
problems as follow:
 
    1. When I build the tests, the test program 
for strtoul will fail.
    2. When I build the library and tests, the 
program s_tanh will fail.
 
    To solve the problems, I modified the cdl 
for stdlib and libm, and it works. And I found that those tow programs are the 
last item of the cdl file. I hope this will be useful.
 
    And after I modified the cdl files, the 
corresponding makefile did not update, does it correct???
 
    Thanks for the help from the mail 
list.

Please adjust your email software to send in plain text only. Not
everybody uses MIME-aware mail readers, and sending messages in both
text and html is just a waste of bandwidth.

You do not say what changes you have made to the CDL files so I cannot
comment on whether or not that is a sensible way of fixing the
problems with strtoul and s_tanh. However, after making any changes to
a CDL file or to a saved configuration it is necessary to regenerate
the build tree. From the command line this means running "ecosconfig
tree" again. When using the GUI tool I suspect you will have to exit
and restart the tool.

Adding makefile support for regenerating the build tree automatically
following a change to the saved configuration or to a CDL script,
along similar lines to autoconf's --enable-maintainer-mode facility,
is on the to do list. There are some implementation difficulties,
especially consistency problems for people using the GUI tool.

You *still* haven't described what exactly fails, with an excerpt of the
error output. No-one can help you until you do!
