rrc-dump doesn't compile

[DerrickMartinez]

I got the latest spec of 25331 (C10) Rel 12 and copied it into my directory. After several minutes of successful compiled code, it blows up at:

I got it compiled by fixing the code, but I just wanted to make it known here.

Great you got it compiling!

The current code generation approach would not allow me to quickly change the anonymous structures in macro thing which breaks your compiler. One approach would be to use gcc to compile this module, and use this library with the rest of the project using that non-gcc/clang compiler that you're apparently using.

[olegarch]

Same with gcc:
gcc -DASN_PDU_COLLECTION -I. -o PLMNIdentitiesOfNeighbourCells-v860ext.o -c PLMNIdentitiesOfNeighbourCells-v860ext.c

MultiplePLMNsOfInterFreqCellsList.h:29:10: error: redefinition of ‘struct multiplePLMN_list’
struct multiplePLMN_list {

Can you share the fix you did?

hi, @olegarch and @msivaprakash,

I found that for the two IEs MultiplePLMNsOfInterFreqCellsList and MultiplePLMNsOfIntraFreqCellsList in 25.331's ASN.1 definition :

MultiplePLMNsOfInterFreqCellsList ::=   SEQUENCE (SIZE (1..maxCellMeas)) OF SEQUENCE {
    multiplePLMN-list   SEQUENCE (SIZE (1..6)) OF PLMN-IdentityWithOptionalMCC-r6 OPTIONAL
}

MultiplePLMNsOfIntraFreqCellsList ::=   SEQUENCE (SIZE (1..maxCellMeas)) OF SEQUENCE {
    multiplePLMN-list   SEQUENCE (SIZE (1..6)) OF PLMN-IdentityWithOptionalMCC-r6 OPTIONAL
}

MultiplePLMN-List ::= SEQUENCE (SIZE (1..6)) OF PLMN-IdentityWithOptionalMCC-r6

Since IE MultiplePLMN-List has the same construction as member multiplePLMN-list inside these two IEs. If I replace them as :

MultiplePLMNsOfInterFreqCellsList ::=   SEQUENCE (SIZE (1..maxCellMeas)) OF SEQUENCE {
    multiplePLMN-list   MultiplePLMN-List OPTIONAL
}

MultiplePLMNsOfIntraFreqCellsList ::=   SEQUENCE (SIZE (1..maxCellMeas)) OF SEQUENCE {
    multiplePLMN-list   MultiplePLMN-List OPTIONAL
}

MultiplePLMN-List ::= SEQUENCE (SIZE (1..6)) OF PLMN-IdentityWithOptionalMCC-r6

Then the generated C code can be compiled successfully using gcc 5.4.0 on Lubuntu 16.04

For your reference.
