- Easy to use (that is why we call it EasyAsn)
- Automatically generate codec source codes (C style only for the moment) for 3GPP NGAP, S1AP, X2AP, XNAP etc.
- Automatically generate dummy test source codes
- Automatically generate wireshark-like message dumpping codes (for trouble-shootings)
-
Prerequisite
Any Linux style system with gcc 4.3.0 or above.
-
Clone project to local folder, saying /workings/tmp/easyasn_ngap
NOTE: Do not change the sub folders' structure.
-
Generate example codec using the shipped tool asn_aper_gen_v125
linux-vm2:/ # cd /workings/tmp/easyasn_ngap/
linux-vm2:/workings/tmp/easyasn_ngap # ls
