Well to have full debuging support (ie. filenames and line numbers in gdb) |
| 13 |
you need to add -g to your CFLAGS and export the env variable DEBUGBUILD |
| 14 |
(which will stop the debuging symbols being striped). |
| 15 |
If just having the function names in a gdb backtrace is enough just make |
| 16 |
sure -fomit-frame-pointer is NOT in your CFLAGS. |
| 17 |
Full debug support will take up ALOT more space and isn't really needed as |
| 18 |
you rarely have to debug system libraries. I just compile the application |
| 19 |
which I am working on with -g, just getting the function names in gdb for |
| 20 |
libraries is fine for me. |
