-B

Category

Compiler customization

Pragma equivalent

None.

Purpose

Specifies substitute path names for XL C/C++ components such as the assembler, C preprocessor, and linker.

You can use this option if you want to keep multiple levels of some or all of the XL C/C++ executables and have the option of specifying which one you want to use. However, it is preferred that you use the -qpath option to accomplish this instead.

Defaults

The default paths for the compiler executables are defined in the compiler configuration file.

Parameters

prefix

Defines part of a path name for programs you can name with the -t option. You must add a slash (/). If you specify the -B option without the prefix, the default prefix is /lib/o.

Usage

The -t option specifies the programs to which the -B prefix name is to be appended; see -t for a list of these. If you use the -B option without -tprograms, the prefix you specify applies to all of the compiler executables.

The -B and -t options override the -F option.

Predefined macros

None.
