Most probably the layer23 has not been configured with |--enable-transceiver flag. Try to reconfigure it with using the following commands |

cd |/root/trx/src/host/layer23/     ./configure --enable-transceiver     make|| |

And if it still fails execute the following commands and provide their full output

for lib in $(find / -name libosmodsp.so); do echo $lib; objdump -T $lib | grep osmo_cxvec_free; done     grep osmo_cxvec_free $(find / -name cxvec.h)| ||||head -10 /root/trx/src/host/layer23/config.log || ||grep -i "OSMODSP" |/root/trx/src/host/layer23/config.log ||    grep -R -i "OSMODSP" |/root/trx/src/host/layer23/src/transceiver/| ||||||||cd |||||||||/root/trx/src/host/layer23/src/transceiver/| && make V=1|||||||| ||||

Hello I was able to reproduce the bug to compile transceiver don't go in /root/trx/src/host/layer23/src/transceiver make fails here Rather than that do the following go to root folder # git clone https://github.com/osmocom/osmocom-bb trx

# cd trx/src # nano target/firmware/Makefile (tx enable...) # git checkout jolly/testing # make HOST_layer23_CONFARGS=--enable-transceiver

*Shell #3* # cd trx/src/host/layer23/src/transceiver/ # sudo ./transceiver -a [YOUR ARFCN FOUND WITH RSSI] -2 -r 99 This command doesnt work in trx folder. (kali 18.1)

How to build transceiver file ?
