[Ace-users] Re: [tao-users] [tao-bugzilla] : ["tao_idl -GA" can generateincompilable code]

[Johnny Willemsen]

Hi,

Thanks for using the PRF form. The -GA option is added to reduce footprint
but has it restrictions. In the past it was more flexible but because of the
refactoring of the Any/TypeCode support we had to change it a little. Try to
move the Exception out of the interface, then it should generate compiling
code again, or remove the -GA option from the commandline.

Regards,
