[omniORB] omniidl2 compiler bug ????? in omniORB2.6.0

[Gary D. Duzan]

   I haven't checked your IDL specifically, but it sounds somewhat like
a bug I uncovered recently which had to do with proprocessor #line
directives. Try the attached patch and see if it helps. You'll probably
have to do a:

  chmod u+w src/tool/omniidl2/fe/lex.yy.cc

before applying the patch. If this doesn't help, you might look for
similar code in the same file.

=>Hi CORBAholics,
=>
=>it's me again and I have found a strange behaviour of the idl compiler
=>in omniORB 2.6.0.
=>It was possible to reduce my very complex idl files to an example which
=>shows following
=>error while compile time:
=>
=>omniidl2: "/tmp/idli_a05314.cc", line 16: error in lookup of symbol:
=>MyException
=>omniidl2: Main.idl: found 1 error
=>
=>This error indicates that the include statement doesn't work. Some
=>changes to the code
=>leave to a complete compilation (all changes to Main.idl)
=>
=>If I delete the comment in the first line -> it works
=>If I delete the comment only, leaving two lines before the #ifndef -> it
=>doesn't work
=>If I insert a comment line "// abcdefg" between #define and first
=>#include -> it works
=>
=>I think it's very very very strange. Does anybody be able to reconstruct
=>this error with his
=>2.6 idl compiler? If yes it could be a bug (one have to be careful with
=>such a statement right?)
=>If no, it could help us to find hints for the error source

=>Best regards
