Dynare forums

Hi,

I have tried to install Dynare on Mac OS Lion and ran into a couple of issues: First I tried this using matlab 2010b and 2011a, same issue;

running build_dynare I get this result:

Note: I have Xcode 4.1 installed and there is a c compiler on my mac. Any suggestions how I can get this to work? Thanks.

Hi,

Following the instructions found here: http://www.dynare.org/DynareWiki/InstallOnMacOSX I have been able to build the Dynare mex files and run dynare on OS X Lion.

Are you certain you have installed the latest version of Xcode (4.1.1)? The reason I ask is that when you run the configure script, it does not find make:

checking whether make sets $(MAKE)... no

, which would obviously not allow you to build the mex files. If you open Terminal (Applications->Utilities->Terminal.app) and type

Code: Select all

make --version

at the command prompt, what's the output? If you then type

Code: Select all

gcc --version

, what's the output? Please also do the same in Matlab (i.e., open Matlab and at the prompt type:

Code: Select all

system('make --version')

and

Code: Select all

system('gcc --version')

) and send me the output.

Also, please post

Code: Select all

/Applications/Dynare/4.2.1/src/mex/build/matlab/config.log

Best,
Houtan

thanks.
I got it to work. For some reason it worked after un- and reinstalling Xcode.
