In Response To: esqlc / warning messages (Charles, Emma)

Someone else told you the way to retain the ESQL/C file (and the C file,
and the 4EC file) is with the -keep option.

It is helpful to include platform and version information. Which version
6.0x are you using - I'd be surprised if that is not what you are using.

The problem is some fallout from the dreaded bug number 31661 (it's still
seared into my brain these 7 years later). I suspect that most of the
answer is 'upgrade' as the issue has been substantially resolved in the
latest releases of I4GL. However, what is happening is that I4GL is
attempting to preserve the pre-6.00 behaviour of keeping statement names
private to a source file even though the underlying ESQL/C has changed the
behaviour (starting with ESQL/C 5.00 - there was no version of I4GL that
used ESQL/C 5.x) so that statement names are global to an application. It
does this by "mangling" the name you write - hence the I0000166F_0FD5F679
identifier which you did not write in your source code. The mangling
algorithm first used was far from perfect (sorry), and sometimes hashed two
distinct statement names to the same hashed value. And, apparently, this
problem is afflicting you. If you track down the statement name in the
source code and change it (radically), the problem should vanish. Or, as I
suggested, you can try an upgrade instead (or as well).

There's a lot more that could be said; there are more recent bug numbers
than B31661 that apply, but that is the original bug.

CONFIDENTIALITY [...does not apply to publicly posted messages...]

I am trying to compile a 4GL program and come across a warning message as :

c4gl -c -I/usr/informix/incl ecform24.4gl

esqlc: "ecform24.ec", line 587: Warning -33071: The statement id
'I0000166F_0FD5
F679' has already been used.

1 warning(s)

The compilation is successful and the 4ge is made (ecform24.4ge)

However, I do not like this warning message and there is no way to read the

line 587 from ecform24.ec as this file is already deleted after
compilation.
