Dynare forums

Hello all,

I am new to Matlab and Dynare but am fairly comfortable with other languages and numerical libraries. I have two problems installing Dynare. I am using the student version of matlab v. 7.8. The student version (unfortunately) only comes in 32-bit, and I am running 64-bit *ubuntu 9.10. I have successfully run the following

./configure --with-matlab=~/matlab MATLAB_VER=7.8
make

But when I run

make check

I receive the following error:

<snip>
Starting MATLAB/Octave computing.

error: DYNARE: Can't find bytecode DLL. Please compile it or remove the 'bytecode' option.
error: called from:

I am on linux, so I wouldn't have any DLLs. Is this a problem with my octave build or dynare? If dynare, what flag should I use to disable bytecode?

Figuring this error might not be such a big deal, I then sudo

make install

I receive the following error:

This directory doesn't exist, because I have the student 32-bit matlab, and the directory is ~/matlab/extern/lib/glnx86/. Possibly unrelated, but I tried to set MEXEXT=mexglx in the configure step, but I also got a complaint there. The matlab installer also had a similar problem with respect to its java runtime environment and I had to create a symbolic link to the glnx86 directory. Might something like that work in this situation?

Thanks for any help,
Skipper

For the record, I am building from source because I have compiled my own lapack/atlas from source, Octave from source and the packaged binaries also fail probably because of the mismatch between matlab 32-bit and my architecture.

Gotten a little further. I went ahead and created the symbolic link, so I no longer get the directory does not exist error. However, I get a -lmx cannot be found error. This is I think occurring because I'm using 32-bit matlab...

So I deleted the source directory and started over. Unzip the source, run

./configure --with-matlab=/PATH/TO/MATLAB MATLAB_VERSION=7.8 MEXEXT=mexglx

make

Now I get the error

How can I tell the configure step that I am using a 32-bit matlab? Do I just need to set compiler and linker flags = m32?

Any help would be appreciated, I'm tearing my hair out.

Hi,

Your problem seems complicated, for two reasons: you're using your own Octave build, and your MATLAB 32-bit doesn't match your 64-bit arch.

I suggest the following:

• configure Dynare without specifying a PATH to matlab, or even with the "--disable-matlab" option. Then "make" and "make check". You should get a fully working version of Dynare for Octave. If that fails, it is a problem with your Octave setup. Note that there is no "make install": you run Dynare from the place where you unpacked the source archive
• then, compile the MEX files from the MATLAB prompt by running the "build_matlab.m" script under "mex/sources"

Hope this can help

Best

I am back, because my preprocessor is failing undoubtedly due to build issues.

Ok I did this.

./configure
make
make check

Everything seems to be ok, except a test error due to my ATLAS install handled here.

Ok so I go into mex/sources and after changing my matlab/bin/mexopts.sh to use gcc-4.2 and g++-4.2, I get the following errors

$ matlab -nodesktop

Delete old mex files.

Two things that I notice.

One, I do not have a matlab/bin/glnxa64 but I am used to this with the 32-bit matlab so I make a symlink there from glnxa64 to glnx86 and it still is the same output.

Two, I don't have this lmwlapack, lmwblas, but I do have a system-wide liblapack.so can I just use this? If so, how do I point to /usr/lib/liblapack.so etc.

Thanks!

Skipper

Hmm, seems like I recall going through this with other packages before.

I renamed lmwlapack, etc. to

llapack, lblas, and ldl and now the output is

So basically, it still thinks I have 64 bit matlab even with the symlink set. Anyone know how I can specify my Arch manually? I don't see how to in mexopts.sh or in build_matlab.

Sorry for all the noise. Now I am just posting for posterity. Ok if you add

Arch="glnx86" right before the "case" switch in mexopts.sh then it will choose your right 32-bit install for 64-bit os, but now it tries to link against my system lapack, which is of course...64-bit!!

Am I going to have to build a 32-bit lapack to get this to install for 32-bit matlab or is there any other way to proceed?

Duh. Okay, matlab provides the needed lapack files. So switch this back to lmwlapack etc. Now, you need 32-bit compatible compilers, so sudo apt-get gcc-4.2-multilib I also created symlinks in /usr/lib32/ I'm not sure this step is completely necessary.

sudo ln -s libstdc++.so.6 libstdc++.so
sudo ln -s libgcc_s.so.1 libgcc_s.so

At this point, I received an error about some of the Dynare source saying that the compiled sparse_kroneker wasn't for i386. I thought it was maybe from a previously failed build, so I deleted everything, got the 4.1.1 source. Now I want to build, but it looks like the problem is with Dynare now. I want to keep everything the same, compilers, 32-bit, so I try to do the following, but how do I

./configure CC='gcc-4.2' CFLAGS='-m32' CXXFLAGS='-m32' CXX='g++-4.2' FFLAGS='-m32' --with-matlab=/home/skipper/matlab/ MATLAB_VERSION=7.8 mexext=mexglx

However it still thinks I want to use glnxa64 when I want glnx86. How can I tell Dynare this in the configure step? I am at the end of my capabilities here. After doing the above, I get

Whew. I think I got it working after some more fiddling, but I am not sure this is a correct installation, as I'm still seeing pre-processing failures. These are the steps that worked for me to build Dynare with 64 bit linux and a student version 32 bit matlab.

Make sure you have compatible compilers for matlab. This means gcc <= 4.2. You also need 32-bit compilers so

sudo apt-get install gcc-4.2 g++-4.2 gcc-4.2-multilib g++-4.2-multilib

You need to go into $MATLAB/bin and edit your mexpots.sh. Around line 33 before the "case" switch line insert on its line Arch="glnx86";. In the glnx86 section, make sure that CC="gcc-4.2" and CXX="g++-4.2". For some reason the CXXFLAGS did not include "-m32" but all the others did. Add this flag to the CXXFLAGS line. I then made the symlinks mentioned above, but I don't know that this was necessary. I got the dynare-4.1.1 source, untar'd and did

./configure --disable-octave --disable-matlab CFLAGS='-m32' CXXFLAGS='-m32' LDFLAGS='-m32'

I had to disable octave, because my octave build is 64-bit. The rest are flags to the compilers and linkers to make sure everything is 32-bit. Then

make

I skipped make check because it tries to use Octave (run_test_octave.m can't find the BYTECODE DLL) and fails. Then I cd'd to ./mex/sources

matlab -nodesktop
>>>build_matlab

I didn't receive any errors, so I guess that's that.
