Arguments

n

Is the ABI implementation. Possible values are:

0	Requests the latest ABI implementation.
1	Requests the ABI implementation used in gcc 3.2 and gcc 3.3.
2	Requests the ABI implementation used in gcc 3.4 and higher.

Default

Varies

The compiler uses the ABI implementation that corresponds to the installed version of gcc.

Description

This option tells the compiler to select a specific ABI implementation. This option is compatible with gcc option -fabi-version. If you have multiple versions of gcc installed, the compiler may change the value of n depending on which gcc is detected in your path.

Note

gcc 3.2 and 3.3 are not fully ABI-compliant, but gcc 3.4 is highly ABI-compliant.

Caution

Do not mix different values for -fabi-version in one link.

Alternate Options
