3D Interoperability

[amcom]

According to this link http://doc.spatial.com/index.php/Compiler_Flags_for_Windows_32-bit_Visual_C%2B%2B_2005_SP1 , SPA_NO_AUTO_LINK needs to be included in both debug and release project settings.

In my project, I have no problem for debug version. However, I got linking errors for release version (see below). The errors are gone if I remove SPA_NO_AUTO_LINK from the settings.

I am using VS 2005, SP1 and Windows XP, 32 bits.

I forgot to put my quesiton in the last post.

Is it OK to remove SPA_NO_AUTO_LINK from the project settings?

Thanks.

hello,

       we are able to reproduce the issue. We have found that this is the case with R21SP3. We are looking more into it. As of now I suggest not to use SPA_NO_AUTO_LINK.

Hi,

We could reproduce issue with Options.We got linking errors "error LNK2019: unresolved external symbol".However to reproduce user scenario we will require your sample project.Can you please create incident and attach sample project?

Thanks,

Hi,

With Options we are getting following linking errors after setting SPA_NO_AUTO_LINK

Error    9    error LNK2019: unresolved external symbol "__declspec(dllimport) public: __thiscall spa_unlock_result::~spa_unlock_result(void)" (__imp_??1spa_unlock_result@@QAE@XZ) referenced in function "void __cdecl unlock_license(void)" (?unlock_license@@YAXXZ)    unlock_license.obj

These linking errors are diffrent than what you mentioned.So to reproduce exact issue we request you to provide sample project by creating incident.

Thanks,

Sorry for late response. I was on vacation in last couple weeks.

Here is the sample project having link problems in release version. It is a dll to convert a catiav5 file to a iges file.

Another question if you can help. I got crash in debug mode after I finish the conversion. It happens when I try to exit the application. It stops at crtexe.c, line 610. Thanks.

if( !managedapp )

exit(mainret);

if(has_cctor == 0)

_cexit();
