Stupid standards writers really abuse ASN.1, making it impossible for their definitions to compile with "normal" tools.

This seems to be yet another example of that. I think the cause is circular dependency similar to #78 that you hit in XNAP. I suspect the solution would be similar too...

Maybe re-ordering the ASN.1 files that were concatenated together could help? I don't know.

Wish I could help more. But extending asn1c to handle this is beyond my skill and available time.

from asn1c.

@gatopeich I checked the generated *.[ch] files, and observed this:

$ rg asn_PER_memb_id_constr_282 *.[ch]
ProtocolExtensionField.c
12103:static asn_per_constraints_t asn_PER_memb_id_constr_282 CC_NOTUSED = {
23585:			&asn_PER_memb_id_constr_282,

ProtocolIE-Field.c
18573:static asn_per_constraints_t asn_PER_memb_id_constr_282 CC_NOTUSED = {
30409:			&asn_PER_memb_id_constr_282,

Perhaps your problem is caused by CC_NOTUSED? If CC_NOTUSED is present - perhaps you can manually remove it from the definition, and try to compile again?

Also, I tried to compile the converter-example, but apparently the order of the includes and their circular dependencies are in the way. Do you have a way past this?

Yep, I worked around the (apparent) circular deps by manually reordering ProtocolIE-Field file, like explained in #78
The dependencies are not really circular, but they are badly ordered when generating Protocol-XXX files.
