Hi @rajugbv,

If the application is not present after you rebuilt the code, then there was most likely an issue and it did not build correctly. I suggest you try to build the code again paying close attention that there are no errors. Also, double-check that you have reinstalled the dependencies correctly after formatting your PC.

But it finds SCTP library, see log

yes i did, as i am was using Ubuntu i have run this command "sudo apt-get install cmake make gcc g++ pkg-config libfftw3-dev libmbedtls-dev libsctp-dev libyaml-cpp-dev libgtest-dev"

Note that cmake ../ only prepares a bunch of Makefiles in the build directory. To do the actual build, you have to run make or make -j NUM with NUM being the number of CPUs.

**this are the file changes i have done in /home/raju/open5gs/configs/open5gs path

in srsran this are the changes i have done**

so when i tried to run the gnb application i am getting this error below
. is there any problem with config or there is issue with srsran application?

raju@raju-ThinkPad-P16s-Gen-1:~/srsRAN_Project/build/apps/gnb$ sudo ./gnb -c /home/raju/srsRAN_Project/configs/gnb_rf_b200_tdd_n78_20mhz.yml

Start your AMF first then start gNB so that a SCTP connection can be established

It looks like an issue in your AMF configuration file. Please go through this guide extensively - https://open5gs.org/open5gs/docs/guide/01-quickstart/ to configure your AMF correctly
