Can't compile EXTERNAL type

[immesys]

I'm trying to compile the following:

My-Schema DEFINITIONS ::=
BEGIN

  MyObject ::= EXTERNAL

END

And I get

FATAL: Cannot compile "MyObject" (4a:1) at line 4
FATAL: Cannot compile "MyObject" (4a:1) at line 4

What am I doing wrong?

Hi @immesys,

See #140. You need to apply b3bdced to the master.
Tomorrow I'll try to rebase it and open a PR.

You could also try these forks

https://github.com/mouse07410/asn1c/tree/master
https://github.com/brchiu/asn1c/tree/mouse_master_misc_changes

[immesys]

I am struggling with both of those forks. Mouse07410 master gives:

gcc: error: asn1p_l.c: No such file or directory
gcc: fatal error: no input files
compilation terminated.

And the brchiu branch compiles but when run on the snippet above gives:

FATAL: Unknown type "EXTERNAL" referenced by "MyObject" at line 6 in foo.asn

If you manage to rebase an open a PR I would be very grateful. Thanks!

Here it is #295

The EXTERNAL is tested in

asn1c/tests/tests-asn1c-compiler/159-EXTERNAL-OK.asn1

Lines 1 to 4 in 6dba416

	TEST DEFINITIONS ::=
	BEGIN
	T ::= EXTERNAL
	END

asn1c/tests/tests-c-compiler/check-src/check-159.c

Lines 122 to 126 in 6dba416

	/* Check exact buf1 */
	check(&t, buf1, sizeof(buf1), sizeof(buf1));
	compare(&t, buf1_reconstr, sizeof(buf1_reconstr));
	asn_fprint(stderr, &asn_DEF_T, &t);
	ASN_STRUCT_FREE_CONTENTS_ONLY(asn_DEF_T, &t);

And the Travis builds

@velichkov could I ask you to rebase and submit your PR against https://github.com/mouse07410/asn1c/tree/vlm_master ? I tried to apply your PR #295 as-is, but got several conflicts that I can't resolve on my own. :-(

I thought support for EXTERNAL was merged last year - but it appears that it's not there. I'm getting the same error as the OP does:

$ asn1c -v
ASN.1 Compiler, v0.9.29
Copyright (c) 2003-2017 Lev Walkin <[email protected]> and contributors.
$ cat MySchema.asn1 
MySchema DEFINITIONS ::=
BEGIN

  MyObject ::= EXTERNAL

END
$ asn1c MySchema.asn1 
FATAL: Cannot compile "MyObject" (4a:1) at line 4
FATAL: Cannot compile "MyObject" (4a:1) at line 4
$

P.S. https://github.com/mouse07410/asn1c/tree/vlm_master is the current default of my fork, and should be used for all the work. https://github.com/mouse07410/asn1c/tree/master is old, doesn't have the latest updates and fixes merged, and does not have OER support.

The way the tests are organized, makes supporting multiple forks very difficult.

Thank you!!

The way the tests are organized, makes supporting multiple forks very difficult.

Is there anything we can do about it? Say, one big radical change that would make life easier down the road?
