-qpath
Category
Pragma equivalent
None.
Purpose
Specifies substitute path names for XL C/C++ components such as the compiler, assembler, linker, and preprocessor.
You can use this option if you want to keep multiple levels of some or all of the XL C/C++ components and have the option of specifying which one you want to use. This option is preferred over the -B and -t options.
Syntax
.-------. V | >>- -q--path--=----+-a-+-+--:--directory_path------------------>< +-b-+ +-c-+ +-C-+ +-d-+ +-I-+ +-L-+ +-l-+ '-p-'
Defaults
By default, the compiler uses the paths for compiler components defined in the configuration file.
Parameters
- directory_path
- The path to the directory where the alternate programs are located.
The following table shows the correspondence between -qpath parameters and the component names:
| Parameter | Description | Component name |
|---|---|---|
| a | The assembler | as |
| b | The low-level optimizer | xlCcode |
| c, C | The C and C++ compiler front end | xlCentry |
| d | The disassembler | dis |
| I (uppercase i) | The high-level optimizer, compile step | ipa |
| L | The high-level optimizer, link step | ipa |
| l (lowercase L) | The linker | ld |
| p | The preprocessor | xlCentry |
Usage
The -qpath option overrides the -F, -t, and -B options.
Predefined macros
None.
Examples
To compile myprogram.c using
a substitute xlc compiler
in /lib/tmp/mine/ enter:
xlc myprogram.c -qpath=c:/lib/tmp/mine/To compile myprogram.c using a
substitute linker in /lib/tmp/mine/,
enter:
xlc myprogram.c -qpath=l:/lib/tmp/mine/
