1 | # Hints for the PowerUX operating system running on Concurrent (formerly |
2 | # Harris) NightHawk machines. Written by Tom.Horsley@mail.ccur.com | |

4 | # Note: The OS is fated to change names again to PowerMAX OS, but this |
5 | # PowerUX file should still work (I wish marketing would make up their mind | |
6 | # about the name :-). | |

8 | # This config uses dynamic linking and the Concurrent C compiler. It has | |
9 | # been tested on Power PC based 6000 series machines running PowerUX. | |

2755218d | 11 | # Internally at Concurrent, we use a source management tool which winds up |
94b6baf5 AD |
12 | # giving us read-only copies of source trees that are mostly symbolic links. |
13 | # That upsets the perl build process when it tries to edit opcode.h and | |
14 | # embed.h or touch perly.c or perly.h, so turn those files into "real" files | |
15 | # when Configure runs. (If you already have "real" source files, this won't | |
16 | # do anything). | |

84 | # PowerMAX OS has support for a few different kinds of filesystems. The |
