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.
