- I have gcc 2.3.1 compiled on a DECstation 3100, Ultrix 4.2.
- ghostscript 2.5.2 compiles with gcc without giving any warning
- messages, but when I try to run it. I get the following message
-
- > ./gs -DNODISPLAY
- Initializing... Unrecoverable error: Unrecoverable error: Unrecoverable error: Unrecoverable error: Unrecoverable error: Unrecoverable error: Unrecoverable error: Unreco
-
- The "Unrecoverable error" keeps repeating as fast as possible. Ultrix
- cc compiles gs 2.5.2 correctly.
-
- I did some hunting with gdb, and the following may be useful. I can't
- be sure because I don't know ghostscript well enough.
-
- (gdb) cont
- Continuing.
