Platform configuration files for the SCons based build system |
| 2 |
------------------------------------------------------------- |

|

<platform>.cfg |
| 5 |
-------------- |
| 6 |
|
| 7 |
The <platform>.cfg files in this directory are used to determine |
| 8 |
the right settings, libraries, source files etc. on the platform |
| 9 |
where you are building Radiance. The build system will select the |
| 10 |
appropriate file automatically. |
| 11 |
|
| 12 |
If your platform isn't supported yet, then you can create a new |
| 13 |
file with an appropriat name (SCons should tell you what it |
| 14 |
expects). Usually, you will start by copying the file of the most |
| 15 |
similar suupported platform, and then make the necessary changes. |
| 16 |
|
| 17 |
On unix based platforms without a specific config file, the file |
| 18 |
"posix.cfg" will be used (which may or may not work well enough). |
| 19 |
|
| 20 |
As of this writing, the following platforms are included |
| 21 |
(although not all of them have been tested very recently): |
| 22 |
|
| 23 |
* linux.cfg Linux |
| 24 |
* freebsd.cfg FreeBSD unix |
| 25 |
* darwin.cfg Macintosh OS-X |
| 26 |
* sunos.cfg Sun Microsysems Solaris Unix |
| 27 |
* irix.cfg sgi IRIX Unix release 5.x or later |
| 28 |
* irix4.cfg sgi IRIX Unix release 4.x (obsolete) |
| 29 |
* irix3.cfg sgi IRIX Unix release 3.x (obsolete) |
| 30 |
* hpux.cfg Hewlett Packard HP-Unix |
| 31 |
* aix.cfg IBM AIX Unix |
| 32 |
* posix.cfg default for unknown Unix systems |
| 33 |
* win32.cfg MS Windows (Visual C compilers) |
| 34 |
* cygwin.cfg Cygwin on MS Windows http://www.cygwin.com/ |
| 35 |
* mingw.cfg MingW on MS Windows http://www.mingw.org/ |

<platform>_custom.cfg |
| 39 |
--------------------- |
| 40 |
|
| 41 |
If you want to experiment with changes to the shipped file, then |
| 42 |
you can create a copy named <platform>_custom.cfg, and make your |
| 43 |
changes there. If such a file exists, then it will be used in |
| 44 |
place of the original. |
| 45 |

Contents and format |
| 48 |
------------------- |
| 49 |
|
| 50 |
Any text starting with a hash character (#) until the end of the |
| 51 |
line is ignored as a comment. |
| 52 |
|
| 53 |
A config file consists of several sections, each of which is |
| 54 |
introduced by a keyword in brackets. |
| 55 |
Within each section, a configuration directive starts with a |
| 56 |
keyword and a colon, followed by the data assigned to that keyword. |
| 57 |
