Pragma equivalent
None.
Purpose
Determines substitute path names for XL C/C++ executables 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++ executables and have the option of specifying which one you want to use. This option is preferred over the -B and -t options.
Syntax
>>- -q--path--=--+-a-+--:--directory_path---------------------->< +-b-+ +-c-+ +-C-+ +-d-+ +-E-+ +-f-+ +-I-+ +-L-+ +-l-+ +-m-+ '-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 executable names:
| Parameter | Description | Executable name |
|---|---|---|
| a | Assembler | as |
| b | Low-level optimizer | xlCcode |
| c | Compiler front end | xlcentry, xlCentry |
 C |
C++ compiler front end | xlCentry |
| d | Disassembler | dis |
| E | CreateExportList utility | CreateExportList |
| f |
c++filt utility | c++filt |
| I | High-level optimizer, compile step | ipa |
| L | High-level optimizer, link step | ipa |
| l | Linker | ld |
| m |
Linkage helper | munch |
| p | Preprocessor | n/a |
Usage
The -qpath option overrides the -F, -t, and -B options.
Note that using the p suboption causes the source code to be preprocessed separately before compilation, which can change the way a program is compiled.
Predefined macros
None.
Examples
xlc myprogram.c -qpath=c:/lib/tmp/mine/
xlc myprogram.c -qpath=l:/lib/tmp/mine/
