Can not use a structure in an Import

I had this 'bug' in macOS:
viewtopic.php?t=87191
Now I stumpled across the same error when I use the C backend (x86) in windows:
error: unkonw type_name 's_pjsip_cfg_t'
136 | extern s_pjsip_cfg_t v_pjsip_sip_cfg_var asm("_pjsip_sip_cfg_var");
purebasic.c in function 'f_startsipstack':
purebasic.c46167:20: error: request for member 'f_disable_tcp_swi
More is not visible in the Assembler error message requester.

Did you try with 6.30b3 ? I tried here with x86 and x64 on Windows and it seems to work
Code: Select all
Macro pj_bool_t : i : EndMacro
Structure pjsip_cfg_t Align #PB_Structure_AlignC
allow_port_in_fromto_hdr.pj_bool_t
accept_replace_in_early_state.pj_bool_t
allow_tx_hash_in_uri.pj_bool_t
disable_rport.pj_bool_t
disable_tcp_switch.pj_bool_t
disable_tls_switch.pj_bool_t
follow_early_media_fork.pj_bool_t
req_has_via_alias.pj_bool_t
resolve_hostname_to_get_interface.pj_bool_t
disable_secure_dlg_check.pj_bool_t
use_compact_form.pj_bool_t
accept_multiple_sdp_answers.pj_bool_t
keep_inv_after_tsx_timeout.pj_bool_t
EndStructure
ImportC ""
pjsip_sip_cfg_var.pjsip_cfg_t
EndImport
a = pjsip_sip_cfg_var

I just tried 6.30b3 x86 C backend,
but I can not compile the project because:
Declare does not fit the real procedure
Code: Select all
Structure Object
Server_ID.i
Network_Thread_ID.i
EndStructure
Prototype.i Prototype_Event_Callback(*Object, *Client, Event.i, *Custom_Structure=#Null)
Declare.i Event_Callback(*Object.Object, *Callback.Prototype_Event_Callback)
Code: Select all
Procedure.i Event_Callback(*Object.Object, *Callback.Prototype_Event_Callback)
Declare and Procedure are identical
In 6.21 it works without this problem.

Yes, I corrected this issue for the next beta.

So I have to wait for the next beta to test this.

drop the pointer or move procedure to where you don't need to declare it and leave the pointer
Code: Select all
Declare.i Event_Callback(*Object.Object, Callback.Prototype_Event_Callback)
Procedure.i Event_Callback(*Object.Object, Callback.Prototype_Event_Callback)
When I came across it, I suffered a little hair loss from being a dyslexic

I still can not compile the code with the C compiler. (PB 6.30 beta 4 x86 windows)
Now I get a PureBasic - Assembler error window with:
error: exected expression before ',' token 69864 | .cSize equ 2
purebasic.c .69884:26 error: unknown type name 'get'
69884 | movzx eax, byte [edx] ; get type
purebasic.c69885:1 error: expected '=', ',',';

Maybe there is Inline assembler code?

No.
There is no inline assmbler line in th whole project.

Maybe it's from the LTO stage, its not Intel format.

Does PB use LTO (Link Time Optimization)?
But if so, it would be a linker error, not a compiler error.

I think it does use LTO now otherwise I don't see the point of changing from polink
if its not from that then maybe its from the Assembler stage why would the message be in att format.
it's like its compiled the c and then its dumping the disassembly.

Seems like you have inline assembly code in your project, did you check that ? If not, please send me the part of the generated output which show that (you can compile with /COMMENTED flag from the commandline using pbcompilerc.exe
