Problems with vensim compilation

[Christian.Chaboud]

Dear Colleague and Vensim expert,

I try to compile a Vensim program using Microsoft Visual Studio 10.0
My operating system is Vensim7 (64 bites)

After asking for compiled vensim run I obtain the fllowing error message :
-------------------------
LINK : fatal error LNK1104 : impossible d'ouvrir le fichier 'LIBC.lib'
Errors while linking sim.dll - make sure complied simulations were propoerly installed .. .
-------------------------

Thanks for help

I use the following mdl.bat:

What version of Vensim are you using?

[Administrator]

You could also try changing
LINK /DLL /OUT:sim.dll /def:%1sim.def mdl.obj %1simext.obj %1vensim.lib
to
LINK /DLL /OUT:sim.dll /NODEFAULTLIB:libc.lib /def:%1sim.def mdl.obj %1simext.obj %1vensim.lib

I'm not sure it will work though. I've seen the error you specify before when using a MDL.BAT from an old version of Vensim.

Have you tried the modified link line I suggested?

[Christian.Chaboud]

I just used that modification

LINK /DLL /OUT:sim.dll /NODEFAULTLIB:libc.lib /def:%1sim.def mdl.obj %1simext.obj %1vensim.lib


It's OK now on my desktop !!

Thanks Very Much
