<p>Hi,<o:p></o:p></p>
<p>The challenge will be to find the necessary changes for just the compiler, I think the AIX defines where used for both the OS and the compiler. AIX support was removed in 7.1.0, so you could try
<a href="https://urldefense.com/v3/__https:/github.com/DOCGroup/ACE_TAO/releases/tag/ACE*2BTAO-7_0_11__;JQ!!AKgNyAfk550h-spHnEo!YKyXg3N3DW8O2avNcpaLe0DxPlLBl7aTEze8F206vOMtb3hQwa017u3wMrEBfwT73Ay4U3WePiGM86OvwKM9r3M-mg$">
https://github.com/DOCGroup/ACE_TAO/releases/tag/ACE%2BTAO-7_0_11</a> as last version before the code was removed.<o:p></o:p></p>
<p>std::auto_ptr has been removed from C++17, we removed the usage from it from ACE completely, check the documentation what C++ standard is the default for the compiler.<o:p></o:p></p>

<p class="MsoNormal">Hi Johnny, thanks you for responding. I have tried 6.5.21 but it fails as the Open XL C/C++ compiler is very different to the IBM XL C/C++ compiler, both in terms of the actual compiler executable names and the options recognised by the
compiler. I have tried amending the make include file to use the new compiler executable names and to change the compiler options to the Open XL C/C++ equivalents.<o:p></o:p></p>
