Specifies the C++ ABI version for binary compatibility with different levels of GNU C++.
>>- -q--abi_version--=--+-1-+---------------------------------->< '-2-'
where:
- 1
- Specifies the same C++ ABI behavior as in GNU C++ 3.2.
- 2
- Specifies the same C++ ABI behavior as in GNU C++ 3.4, if this version is supported by the Linux operating system.
The option -qabi_version is provided for compatibility with the GNU C++ option -fabi-version=n, which allows the user to specify the version of the C++ abstract binary interface used during compilation. The default setting of -qabi_version depends on the compiling machine itself and the level of GNU C++ configured during the installation of XL C++. The default is -qabi_version=1 if GNU C++ 3.2 or 3.3 is installed on the compiling machine.
Informational messages
The value of -qabi_version can be ascertained by compiling with -qlistopt in effect.
