# SunOS 5.x (Solaris 2.x) with g++

# NOTE: with g++ 2.8.0, you'll need to disable optimization in order to
#       instantiate ACE_Map_Manager (ace/Map_Manager.cpp).  The easiest
#       way to do that is to set "optimize = 0", either below or on
#       your make command line.

# NOTE: On Solaris86, you'll need to use GNU as instead of /usr/ccs/bin/as,
#       if you want -gstabs+ and -pipe support.

    AREA/CLASS/EXAMPLE AFFECTED:
I cannot compile a sample program included at the end that is using a 
sequence<string> construct.

    DOES THE PROBLEM AFFECT:
        COMPILATION? 
My application does not want to compile the included example.

    SYNOPSIS:
I am trying to write a helper function to assign a data value to a 
CORBA::String_out type and it will not compile while attempting to 
process an instance of a sequence<string>.  This code does compile and 
execute properly using orbix.

    DESCRIPTION:
I have the following idl:

    REPEAT BY:

I have tried to compile this on our Solaris box and it will not compile.  
If I move the code to another Solaris box with Forte and orbix, and
slightly massage the #include "myTestC.h" to be "myTest.h", the above
example code will compile and run as expected.


theUserTxId.theAppId  = 1234
theUserData.serverName  = This CORBA string has been populated
theUserData.userPools[0]  = This CORBA string has been populated

    SAMPLE FIX/WORKAROUND:
Use a temporary string object and then do the assignment in the main module.
