Can't Compile External sequences

[ddreyer]

When I compile the following:

BEGIN

  MyObject ::= EXTERNAL

  SomeObject ::= SEQUENCE {
    body SEQUENCE OF MyObject
  }

END

The SEQUENCE member of SomeObject_t, body, compiles as A_SEQUENCE_OF(struct MyObject) list, where MyObject is forward declared but never declared anywhere else. It seems like it should compile to A_SEQUENCE_OF(struct MyObject_t) list. Is this supposed to occur?

Hi @ddreyer,

It seems like it should compile to A_SEQUENCE_OF(struct MyObject_t) list. Is this supposed to occur?

I agree that this could be improved but also it should work as is because this type is used only to define a pointer.

Also note that it is not directly related to the EXTERNAL and you could reproduce it with any other SEQUENCE (and probably with other types as well)

My-Schema DEFINITIONS ::=

BEGIN

MySequence ::= SEQUENCE {
	...
}

MyObject ::= MySequence -- EXTERNAL

SomeObject ::= SEQUENCE {
	body SEQUENCE OF MyObject
}

END

SomeObject.h

/* SomeObject */
typedef struct SomeObject {
	struct body {
		A_SEQUENCE_OF(struct MyObject) list;

MyObject.h

/* MyObject */
typedef MySequence_t	 MyObject_t;

The code that emits the type name in A_SEQUENCE_OF(...) is

asn1c/libasn1compiler/asn1c_C.c

Lines 841 to 843 in 4cc779f

	OUT("%s", asn1c_type_name(arg, memb,
	(memb->marker.flags & EM_UNRECURSE)
	? TNF_RSAFE : TNF_CTYPE));

Understood, it just threw me off a bit because I was expecting a MyObject_t pointer rather than a MyObject pointer.

Also I forgot to mention that I am using this version: #295 (comment)
