model(use_dll) help!

[econactually]

I am trying to run .mod file with 'model(use_dll);' but I when I use dynare command with 'msvc' I have the error below:

??? Error using ==> mex at 208
Unable to complete successfully.

Error in ==> mj at 75
eval('mex -O LINKFLAGS="$LINKFLAGS /export:Dynamic" mj_dynamic.c')

Error in ==> dynare at 132
evalin('base',fname) ;

-->when I use 'cygwin' command instead I get :

??? Error using ==> mex at 208
Unable to complete successfully.

Error in ==> mj at 75
eval('mex -O PRELINK_CMDS1="echo EXPORTS > mex.def & echo mexFunction >> mex.def & echo
Dynamic >> mex.def" mj_dynamic.c')

Error in ==> dynare at 132
evalin('base',fname)



Does anybody know how can I handle these problems?
does using model; or model(use_dll); commands make huge differences? Because the code runs perfectly once I write model; instead of mode(use_dll);.

Thanks

use_dll used to be the only option for higher-order approximations. Today it is mostly a matter of speeding up larger models.
Did you make sure your compiler is installed correctly in Matlab (not Dynare), i.e. used

Code: Select all

mex -setup;

.

Thank you for you reply. So if using model(use_dll) has no difference than just using model anymore, I will continue with using the latter.
