ACE & TAO build fine.
DOES THE PROBLEM AFFECT:
COMPILATION?
LINKING?
On Unix systems, did you run make realclean first?
EXECUTION?
OTHER (please specify)?
My Application is affected on execution, setting up the server. Started from a clean build.
SYNOPSIS:
Upon binding CosNaming::Name I get a SIGABRT from libc, originating from the _this () method generated by TAO_IDL.
