| 3 | some random notes on bulding DAHDI drivers for Sangoma AFT104 cards on a modern Debian 11 / buster |
||
| 4 | |||
| 5 | h2. Sources |

||
| 16 | |||
| 17 | <pre> |
||
| 18 | $ cp ~/dahdi-linux/drivers/dahdi/Module.symvers ~/wanpipe/patches/kdrivers/src/net |
||
| 19 | 2 | laforge | $ make -j4 dahdi DAHDI_DIR=/home/laforge/dahdi-linux KBUILD_EXTRA_SYMBOLS=/home/laforge/dahdi-linux/drivers/dahdi/Module.symvers |
| 20 | 1 | laforge | </pre> |
| 21 | |||
| 22 | 2 | laforge | the importance is to pass the correct Module.symvers from the DAHDI build as KBUILD_EXTRA_SYMBOLS, as otherwise the wanpipe drivers will fail to load with errors like this: |
| 23 | |||
| 24 | 1 | laforge | This somehow fails, the Module.symvers gets overwritten and the module fails with various related errors: |
| 25 | <pre> |
