Re : undefined symbole '_mclInitializeApplication_proxy@8' reference in .c

[jdorne]

hello,

I want to integrate a dll compiled with matlab in a labwindowsCVI project. i have installed matlab runtime r2012b on my pc and add the dll library, mclmcrrt.lib and paths of .h files to the project. I have also included paths « C:\Program Files\MATLAB\MATLAB Compiler Runtime\v80\extern\include » and « C:\Program Files\MATLAB\MATLAB Compiler Runtime\v80\extern\lib\win32\microsoft » to the project.

when compile the project i got this project link error: undefined symbole '_mclInitializeApplication_proxy@8' reference in .c

in mclmcrrt.h i found this #undef mclInitializeApplication #define mclInitializeApplication mclInitializeApplication_proxy

i do include mclmcrrt.h in file .c, could anyone help me with this problem?

Bonjour Jdorne, 

Il faut savoir que CVI utilise aussi le compilateur "lcc", comme vous pouvez le voir sur cette documentation: 
http://digital.ni.com/public.nsf/allkb/A87F4E249F1929ED86257117004C34E8?OpenDocument 

Ensuite concernant l'appel de DLL sous CVI vous avez ce lien : 
http://zone.ni.com/devzone/cda/tut/p/id/3341#toc4

Ce qu'il faut noter c'est : 
"Because LabWindows/CVI is an ANSI C compiler, it can call only functions that have been exported as C-style functions. "

Un forum à déja était posté concernant la création et l'utilisation de dll Matlab sous CVI.

Je vous invite à le consulter.

Je vous souhaite une bonne journée,

Hello Jdorne,
 
You should know that   CVI uses the "lcc" compiler, as you can see from this documentation:

http://digital.ni.com/public.nsf/allkb/A87F4E249F1929ED86257117004C34E8?OpenDocument

Regarding the call of the DLL in CVI :

What should be noted is:

"Because LabWindows / CVI is an ANSI C compiler, it can only call functions That Have Been Exported as C-style functions."
 
 
A forum was already posted on the creation and use of Matlab dll in CVI.

I invite you to consult it.
