[Ace-users] [ace-users] Problems at linkage of TAO to ACE, target VxWorks 6.2

[Douglas C. Schmidt]

Hi,

Thanks for using the PRF.

>CE VERSION: 5.6.1
>
>    HOST MACHINE and OPERATING SYSTEM:
>        Solaris
>
>    TARGET MACHINE and OPERATING SYSTEM, if different from HOST:
>    COMPILER NAME AND VERSION (AND PATCHLEVEL):
>      VxWorks 6.2

I believe that VxWorks 6.2 has some significant bugs that make it hard
to use with ACE+TAO.  Johnny, can you please confirm/deny?

thanks,

Doug
