Dear Sebastien, When trying to use the use_dll-option with Dynare 4.3.0 or .2 (Windows 7 64 with Visual Studio 2010), I get the following error message: LINK : error LNK2001: unresolved external symbol Dynamic C:\Users\Johannes\AppData\Local\Temp\mex_yBgjEV\templib.x : fatal error LNK1120: 1 unresolved externals C:\PROGRA~1\MATLAB\R2011A\BIN\MEX.PL: Error: Link of 'example1_static.mexw64' failed. ??? Error using ==> mex at 208 Unable to complete successfully. Error in ==> example1 at 66 eval('mex -O LINKFLAGS="$LINKFLAGS /export:Dynamic" example1_static.c example1_static_mex.c') Error in ==> dynare at 120 evalin('base',fname) ; 4.2.5 runs on the same machine with use_dll. Any idea what is going on? This is a replication of the problem described here: http://www.dynare.org/phpBB3/viewtopic.php?f=1 <http://www.dynare.org/phpBB3/viewtopic.php?f=1&t=4351> &t=4351 The generated C-files are attached.
