           Summary: Unable to build with gcc 3.3.1
           Product: kdevelop
           Version: CVS
          Platform: Mandrake RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kdevelop-devel at kdevelop.org
        ReportedBy: chris at hypocrite.org


Version:           CVS (using KDE KDE 3.1.3)
Installed from:    Mandrake RPMs
Compiler:          gcc 3.3.1 Default with Mandrake 9.2
OS:          Linux

I am unable to compile KDevelop from cvs.  I reported this to the mailing list several days ago and got confirmation but no help.  I get hundreds of errors compiling the AdaParser.cpp file in languages/ada.  These are all along the lines of:

AdaParser.cpp:34: error: invalid static_cast from type `antlr::RefAST' to type `RefAdaAST'

I get similar error messages in other files, including files dealing with the Pascal language.  The problem seems to stem from the static cast from ASTRefCount<AST> to ASTRefCount<AdaAST> which is, I believe, not allowed under C++ standards.  I could be wrong on that.  Gcc 3.3.x has better support for C++ than 3.2 does which is why this error does not appear with an older version of the compiler.  I will attach a patch which uses C-style casts instead of C++-style casts which at least makes the code compile.  HOWEVER, I believe the cast is invalid and therefore the results (either with the patch or, with an older version of gcc, without the patch) are undefined.
