| 4 | # How to make a DEBUGGING VERSION of perl for DECs cc compiler |
| 5 | # |
| 6 | # If you want to debug perl or want to send a |
| 7 | # stack trace for inclusion into an bug report, call |
| 8 | # Configure with the additional argument -Doptimize=-g2 |
| 9 | # or uncomment this assignment to "optimize": |
| 10 | # |
| 11 | #optimize=-g2 |
| 12 | # |
| 13 | # and (re)run Configure. Note: Configure will automatically |
| 14 | # add the often quoted -DDEBUGGING for you) |

| 50 | # 23-Jan-1997 Achim Bohnet <ach@rosat.mpe-garching.mpg.de> |
| 51 | # |
| 52 | # * Added comments 'how to create a debugging version of perl' |
| 53 | # |
| 54 | # * Fixed logic of this script to prevent stripping of shared |
| 55 | # objects by the loader (see ld man page for -s) is debugging |
| 56 | # is set via the -g switch. |
| 57 | # |
| 58 | # |
| 59 | # 21-Jan-1997 Achim Bohnet <ach@rosat.mpe-garching.mpg.de> |
| 60 | # |
| 61 | # * now 'dl' is always removed from libswanted. Not only if |
| 62 | # optimize is an empty string. |
| 63 | # |
| 64 | # |
| 65 | # 17-Jan-1997 Achim Bohnet <ach@rosat.mpe-garching.mpg.de> |
| 66 | # |
| 67 | # * Removed 'dl' from libswanted: When the FreePort binary |
| 68 | # translator for Sun binaries is installed Configure concludes |
| 69 | # that it should use libdl.x.yz.fpx.so :-( |
| 70 | # Because the dlopen, dlclose,... calls are in the |
| 71 | # C library it not necessary at all to check for the |
| 72 | # dl library. Therefore dl is removed from libswanted. |
| 73 | # |
| 74 | # |
| 75 | # 1-Jan-1997 Achim Bohnet <ach@rosat.mpe-garching.mpg.de> |
| 76 | # |
| 77 | # * Set -Olimit to 3200 because perl_yylex.c got too big |
| 78 | # for the optimizer. |

| 84 | # Where configure gets it wrong: |
| 85 | # |
| 86 | # - FUNCTIONS PROTOTYPES: Because the following search |
| 87 | # |
| 88 | # % grep _NO_PROTO /usr/include/sys/signal.h |
| 89 | # #ifndef _NO_PROTO |
| 90 | # #else /* _NO_PROTO */ |
| 91 | # #endif /* _NO_PROTO */ |
| 92 | # % |
| 93 | # |
| 94 | # is successful and because _NO_PROTO is not included already |
| 95 | # in the ccflags, Configure adds -D_NO_PROTO to ccflags. :-( |
