Dynare forums

I try to compile the SVN version of dynare, but it does not work for mw.

Following the instruction in Dynare Wiki: http://www.dynare.org/DynareWiki/BuildingDlls, I run the build_matlab.m file. Below is the error message:

Furthermore, the compile of the binary file does not work well. Here is the link to the Wiki: http://www.dynare.org/DynareWiki/BuildingPreprocessor.
I type "make" under the same directory where the file "makefile" is . Unfortunately, the message in CYGWIN is too long and can't be copied. After the compilation, when I try running some .mod file, an error message pops up:

'"C:\JH\dynare_v4\dynare_v4_svn\trunk\matlab\dynare_m"' is not recognized as an internal or external command,
operable program or batch file.

Does anyone know how to fix it?

Hi, You have at least three problems here:

1. You are trying to compile with lcc (the c compiler distributed with matlab) files with a cc extension (c++)... I think that for isopenmp.cc and the kronecker product related files you can change the cc extensions with c extensions (these files contain pure c code). But this simple fix won't work for the gensylv related files (these are real c++ files).
2. More generally you have to use gcc instead of lcc, we will never test our routines against lcc.
3. Before the end of the week I will remove from build_matlab.m the compilation of isopenmp.cc. This mex file detects if your PC has a recent openmp library (a library used for parallel computing). But this is a very unstable feature, so we decided to remove this from the matlab script and to create another script for "advanced users".

For the compilation of the preprocessor, I don't know... Could you post, at least, the begining of the error message ? Are you using windows XP/vista 32/64 bits?

Best,
Stéphane.

Thanks for your response, Stephane. How should I compile with gcc, if I only have Matlabe. As for the compilation of preprocessor, I don't know how to copy the messages from CYGWIN. The message is too long and moves too fast. I can only see the end of it. I am using windows XP 32 bit with Matlab 2008b.

You will find some informations about the compilation of the mex files with cygwin/gcc [url=http://www.dynare.org/DynareWiki/BuildingDlls]here[url] (you will need the file mexopts.bat to configure the matlab command mex). I am not a Windows user so I have no experience with this...

You can redirect the output given by the compilation in a log file. For instance, if you type:

Code: Select all

make > make.log


you won't see any output in the command window but a file named make.log will be created (with all the messages inside).

Best, Stéphane.

Deare Stephane:

I figured out the compilation of the preprocessors. Actually, I didn't create the symbolic link in the director /usr/include/mingw. Instead, I copy the file directly. I should type "make" under the directory of preprocessor, instead of "trunk", even the file" makefile" is under the latter directory.

As for the compiling of DLLS. How should I run mexopts in CYGWIN? I run it under windows and it generates a folder under the director of Matlab. Is that supposed to be the case?

Thank you very much for your help.

You do not have to run mexopts.bat, but to save it under your matlab directory as described on the DynareWiki.

Stéphane.
