[omniORB-dev] Compilation Error: OmniORB 4.3.2 on AIX7.2 with xlClang Compiler

[Sasimohan_Chandran at amat.com]

Hi Team,

We are attempting to build OmniORB 4.3.2 on AIX 7.2 using the xlClang compiler.

Compiler Version:
IBM XL C/C++ for AIX, V16.1.0  (5725-C72, 5765-J12)
Version: 16.01.0000.0007
We encountered the following error during the compilation process.
+ rm -f _omniidlmodule.so.4.3

However, we were able to successfully compile using the xlC_r 16.1.0 compiler on the same AIX 7.2 machine.
It appears that different library paths and flags are being used based on the compiler being used. Please refer to the log provided below for more information.

I would like to confirm if OmniORB 4.3.2 is compatible with the xlClang compiler. If it is, please provide us with instructions on how to proceed.

NOTE: "src\tool\omniidl\cxx\cccp\dir.mk" file includes a guard specifically for xlC_r, but there is no such guard for xlClang.
