EiffelStudio 6.2 GPL /COM library error

[Hubert Cater]

If I add the COM library to my project I receive the following error
upon initial compilation:

Visibility Conflict, external class name different: INTEGER_32_REF and
INTEGER_REF

Anyone know why this might be reported and how I can work around this?

I've never seen that particular error, Hubert, but INTEGER_REF is an
alias for INTEGER_32_REF. They are one and the same class: two names,
one class. Maybe your ECF is declaring both names as "visible". Just a
guess.

Hi Peter,

It is a strange error as this is the standard library for COM included
in the 6.2 release.  Looking at the com.ecf file the only reference to
either INTEGER_32_REF or INTEGER_REF is in the following line:

<library name="base" location="$ISE_LIBRARY\library\base\base.ecf">
                        <visible class="INTEGER_32_REF"/>

Changing it to INTEGER_REF did not seem to make a difference.

Just an update that if I removed the offending line, i.e. <visible
class="INTEGER_32_REF"/> from the com.ecf file I was able to
successfully compile but there still seems to be an issue with COM on
6.2 as my projects will not run without an Operating System Signal.

I've submitted a bug report as I can no longer test 6.2 without getting
past this issue.

The issue is that both com.ecf and your ecf file have a different visible clause
for the same class. In your ecf file it is INTEGER_REF and in the com.ecf file it
is INTEGER_32_REF thus the error by the compile, the same class cannot be known
under 2 different names on the non-Eiffel side.
