| 3418 | 1 ## gdb init file for XEmacs -*- ksh -*- |
| 2 ## This is the source for src/.gdbinit. Edit it, and rerun configure. | |
| 3 ## (Running config.status is not enough.) | |
| 4 ## The generated file depends on src/config.h (currently only in one place). | |
| 5 | |
| 6 ## To insert comments that will remain in the generated file, we use the | |
| 7 ## imake XCOMM convention. Lines beginning with "XCOMM " exactly (no | |
| 8 ## leading whitespace, one trailing ASCII space, case sensitive) will be | |
| 9 ## transformed to gdb command file comments in the generated file. | |
| 10 | |
| 11 XCOMM gdb init file for XEmacs | |
| 12 XCOMM AUTOMATICALLY GENERATED FROM etc/gdbinit.in BY configure -- DO NOT EDIT. | |

| 38 ## Some useful commands for debugging emacs with gdb 4.16 or better. | |
| 39 ## | |
| 40 ## Since this file is called `.gdbinit', it will be read by gdb | |
| 41 ## automatically when gdb is run in the build directory, which is where | |
| 42 ## developers usually debug their xemacs. You can also source this | |
| 43 ## file from your ~/.gdbinit, if you like. | |
| 44 ## | |
| 45 ## Configure xemacs with --debug, and compile with -g. | |
| 46 ## | |
| 47 ## See also the question of the XEmacs FAQ, titled | |
| 48 ## "How to Debug an XEmacs problem with a debugger". | |
| 49 ## | |
| 50 ## This can be used to debug XEmacs no matter how the following are | |
| 51 ## specified: | |
| 52 | |
| 53 ## USE_UNION_TYPE | |
| 54 | |
| 55 ## (the above all have configure equivalents) | |
| 56 | |
| 57 ## Some functions defined here require a running process, but most | |
| 58 ## don't. Considerable effort has been expended to this end. | |
| 59 | |
| 60 ## See the dbg_ C support code in src/alloc.c that allows the functions | |
| 61 ## defined in this file to work correctly. | |
| 62 | |
| 63 #define NOT_C_CODE | |
