h1. Sangoma Wanpipe DAHDI some random notes on bulding DAHDI drivers for Sangoma AFT104 cards on a modern Debian 11 / buster h2. Sources * wanpipe 7.0.34 (e.g. via https://git.osmocom.org/wanpipe) * dahdi-linux (e.g. https://github.com/osmocom/dahdi-linux) h2. Building # build + install dahdi-linux #* usual make + sudo make install h3. building sangoma wanpipe drivers <pre> $ cp ~/dahdi-linux/drivers/dahdi/Module.symvers ~/wanpipe/patches/kdrivers/src/net $ make -j4 dahdi DAHDI_DIR=/home/laforge/dahdi-linux KBUILD_EXTRA_SYMBOLS=/home/laforge/dahdi-linux/drivers/dahdi/Module.symvers </pre> 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: This somehow fails, the Module.symvers gets overwritten and the module fails with various related errors: <pre> [ 4874.442680] wanpipe: no symbol version for dahdi_hdlc_putbuf [ 4874.442702] wanpipe: Unknown symbol dahdi_hdlc_putbuf (err -22) [ 4874.442754] wanpipe: no symbol version for _dahdi_ec_span [ 4874.442760] wanpipe: Unknown symbol _dahdi_ec_span (err -22) ..
