tao_idl doesn’t generate all needed C++ code from idls

SYNOPSIS:

tao_idl doesn’t generate all needed C++ code (arg traits, templates) from idls

DESCRIPTION:

Trying to migrate from tao 1.5.10 to tao 3.0.6. Built the latter without issues.
But, when trying to compile the generated C++ code, a compilation error occurs (I tried to set/unset all tao_idl IMHO relevant flags, but no effect), the intermediary goal being a library containing the skeletons:

It appears the tao_idl doesn’t generate anymore the “Arg traits specializations” seen in the tao_idl-1.5.10 – generated C++ file.
Please find attached an archive containing the relevant idls(only in 3.0.6 directory, since common), the 1.5.10 (only BulkDataManagementClientC.cpp) and 3.0.6 generated C++ code (whole relevant).

REPEAT BY:

[What you did to get the error; include test program or session
transcript if at all possible. ]

SAMPLE FIX/WORKAROUND:

[If available ]
tao_idl_3.0.6_error.zip

[jwillemsen]

Please extend the TAO IDL_Test (see https://github.com/DOCGroup/ACE_TAO/tree/master/TAO/tests/IDL_Test) with a small reproducer that triggers the same error.

There is a warning about an anonymous type in your IDL, would recommend to resolve that warning first.

Hello
Sorry, but not being an active contributor to the tao_idl/tao in general (more like a user), I'm unsure what you mean... In the original post I attached an archive which contains, IMHO, all the relevant data, including the IDLs, the corresponding 1.5.10 and all the 3.0.6 generated files.

[jwillemsen]

Please fork the https://github.com/DOCGroup/ACE_TAO repository and extend the IDL_Test with a reproducer IDL. In case you need help, consider commercial support so that someone can assist you with this issue, see https://github.com/DOCGroup/ACE_TAO/wiki/ACE-and-TAO-Commercial-support, that includes @RemedyIT, the company I work for.
