Sangoma Wanpipe DAHDI¶

some random notes on bulding DAHDI drivers for Sangoma AFT104 cards on a modern Debian 11 / buster

Sources¶

• wanpipe 7.0.34 (e.g. via https://git.osmocom.org/wanpipe)
• dahdi-linux (e.g. https://github.com/osmocom/dahdi-linux)

Building¶

1. build + install dahdi-linux
   • usual make + sudo make install

building sangoma wanpipe drivers¶

$ cp ~/dahdi-linux/drivers/dahdi/Module.symvers ~/wanpipe/patches/kdrivers/src/net
$ make -j4 dahdi DAHDI_DIR=/home/laforge/dahdi-linux

This somehow fails, the Module.symvers gets overwritten and the module fails with various related errors:
