EasyAsn

Features

1. Easy to use (that is why we call it EasyAsn)
2. Automatically generate codec source codes (C style only for the moment) for 3GPP NGAP, S1AP, X2AP, XNAP etc.
3. Automatically generate dummy test source codes
4. Automatically generate wireshark-like message dumpping codes (for trouble-shootings)

Quick Start

0. Prerequisite

   Any Linux style system with gcc 4.3.0 or above.

1. Clone project to local folder, saying /workings/tmp/easyasn_ngap

   NOTE: Do not change the sub folders' structure.

2. 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   
   asn_aper_gen_v125  ngap_asn  README  test   
   linux-vm2:/workings/tmp/easyasn_ngap # ./asn_aper_gen_v125 NGAP ./ngap_asn/ngap-class-0.8.0.asn ./ngap_asn/ngap-const-0.8.0.asn ./ngap_asn/ngap-main-1.0.0.asn LTE_ ./test/ngap_codes/

3. Check that codes shall be generated in sub-folder test/ngap_codes

   linux-vm2:/workings/tmp/easyasn_ngap # ls test/ngap_codes/
   LTE_NGAP_Dec.c  LTE_NGAP_Dec.h  LTE_NGAP_DISP.c  LTE_NGAP_DISP.h  LTE_NGAP_Enc.c  LTE_NGAP_Enc.h  LTE_NGAP_IE.h  LTE_NGAP_TST.c  LTE_NGAP_TST.h

4. Build test executable ngap_code_tst based on the generated codes

   linux-vm2:/workings/tmp/easyasn_ngap # cd test/release/   
   linux-vm2:/workings/tmp/easyasn_ngap/test/release # make clean   
   linux-vm2:/workings/tmp/easyasn_ngap/test/release # make
   Building file: ../ngap_codes/LTE_NGAP_DISP.c   
   Invoking: GCC C Compiler   
   gcc -O3 -Wall -c -fmessage-length=0 -MMD -MP -MF"ngap_codes/LTE_NGAP_DISP.d" -MT"ngap_codes/LTE_NGAP_DISP.d" -o "ngap_codes/LTE_NGAP_DISP.o" "../ngap_codes/LTE_NGAP_DISP.c"   
   ...   
   Finished building target: ngap_code_tst

5. Run the test executable and generate a log file

   linux-vm2:/workings/tmp/easyasn_ngap/test/release # ls   
   makefile  manual  ngap_codes  ngap_code_tst   
   linux-vm2:/workings/tmp/easyasn_ngap/test/release # ./ngap_code_tst    
   >> [INFO ] Choice bunch 1 ...   
   >> 1 Test OK, 0 Test failed.

6. The test result is logged into file ngap_src_test.log

   linux-vm2:/workings/tmp/easyasn_ngap/test/release # ls
   
   makefile  manual  ngap_codes  ngap_code_tst  ngap_src_test.log
