Hi professor, I was trying to apply x13 to my data, however, the error said:
What does it mean. How can I solve this problem. Could you please give me a hint. Thank you so much.
Do you have codes to replicate the issue?

Thank you for your help. I am uploading the zip file for your reference. Thank you so much.
Yes I can replicate this on my mac, very weird because on my Linux machine I don’t get this error. So this seems to be mac specific, I’ll investigate this.
Could you run the following commands in a terminal (not MATLAB command window):
/Applications/Dynare/5.2/matlab/modules/dseries/src/../externals/x13/macOS/64/x13as
ls /usr/local/opt/gcc/lib/gcc
ls /opt/homebrew/opt/gcc/lib/gcc
and post the result?
On my machine I get either the following for the Intel version of Dynare:
dyld[7402]: Library not loaded: '/usr/local/opt/gcc/lib/gcc/11/libgfortran.5.dylib'
Referenced from: '/Applications/Dynare/5.2-x86_64/matlab/modules/dseries/externals/x13/macOS/64/x13as'
Reason: tried: '/usr/local/opt/gcc/lib/gcc/11/libgfortran.5.dylib' (no such file), '/usr/local/lib/libgfortran.5.dylib' (no such file), '/usr/lib/libgfortran.5.dylib' (no such file)
or the following error for Dynare’s ARM version:
dyld[7233]: Library not loaded: '/opt/homebrew/opt/gcc/lib/gcc/11/libgfortran.5.dylib'
Referenced from: '/Applications/Dynare/5.2-arm64/matlab/modules/dseries/externals/x13/macOS/64/x13as'
Reason: tried: '/opt/homebrew/opt/gcc/lib/gcc/11/libgfortran.5.dylib' (no such file), '/usr/local/lib/libgfortran.5.dylib' (no such file), '/usr/lib/libgfortran.5.dylib' (no such file)
So for me this was related to different versions of gcc and the required libraries. I had version 12 installed while we use version 11 to compile x13as. So a quick fix is to symlink the folder with the libraries. That is,
- If you’ve installed the Intel version (i.e. you get missing libraries with the above command in the /usr/local folder), then run the following:
ln -s /usr/local/opt/gcc/lib/gcc/12 /usr/local/opt/gcc/lib/gcc/11
- If you’ve installed the ARM version (i.e. you get missing libraries with the above command in the /opt/homebrew folder), then run the following:
ln -s /opt/homebrew/opt/gcc/lib/gcc/12 /opt/homebrew/opt/gcc/lib/gcc/11
But maybe @sebastien has a more elegant way of fixing this?
Thank you so much Professor for your help. I followed what you post and this is the result. When I run the first command, it showed
dyld[3128]: Library not loaded: /usr/local/opt/gcc/lib/gcc/11/libgfortran.5.dylib
Referenced from: /Applications/Dynare/5.2/matlab/modules/dseries/externals/x13/macOS/64/x13as
Reason: tried: '/usr/local/opt/gcc/lib/gcc/11/libgfortran.5.dylib' (no such file), '/usr/local/lib/libgfortran.5.dylib' (no such file), '/usr/lib/libgfortran.5.dylib' (no such file)
Then I run the second command, it said:
ln: /usr/local/opt/gcc/lib/gcc/11: No such file or directory
It seemed still not successful, because the x13 didn’t worked. I post the whole picture here for your reference.How can I solve this problem? Thank you so much again.
I see that you don’t have homebrew installed. Normally, we ship a local homebrew install with the package but for x13as this is somehow not picking up, which is a bug that we would need to fix in a future release. To solve your problem right now, install homebrew and gcc. That is, in the terminal, first install the Intel version of homebrew:
arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
and then the gcc package:
brew install gcc
Lastly, do the symbolic linking;
ln -s /usr/local/opt/gcc/lib/gcc/12 /usr/local/opt/gcc/lib/gcc/11
Thank you so much Professor. I followed your command and the problem was successfully solve. Thank you again!
Hi, I have the same issue but your suggested fix for some reason does not work.
My steps:
- first, I run
/Applications/Dynare/5.2/matlab/modules/dseries/src/../externals/x13/macOS/64/x13as
ls /usr/local/opt/gcc/lib/gcc
ls /opt/homebrew/opt/gcc/lib/gcc
I get the outcome
dyld[47156]: Library not loaded: '/usr/local/opt/gcc/lib/gcc/11/libgfortran.5.dylib'
Referenced from: '/Applications/Dynare/5.2/matlab/modules/dseries/externals/x13/macOS/64/x13as'
Reason: tried: '/usr/local/opt/gcc/lib/gcc/11/libgfortran.5.dylib' (no such file), '/usr/local/lib/libgfortran.5.dylib' (no such file), '/usr/lib/libgfortran.5.dylib' (no such file)
zsh: abort
ls: /usr/local/opt/gcc/lib/gcc: No such file or directory
which is the same to your error for dynare’s Intel version.
-
installed gcc, using
brew install gcc -
If I do
ln -s /usr/local/opt/gcc/lib/gcc/12 /usr/local/opt/gcc/lib/gcc/11,
I getln: /usr/local/opt/gcc/lib/gcc/11: No such file or directory -
If I do
ln -s /opt/homebrew/opt/gcc/lib/gcc/12 /opt/homebrew/opt/gcc/lib/gcc/11,
I getln: /opt/homebrew/opt/gcc/lib/gcc/11/12: File exists
After all these steps, I continue getting the same errors
Thanks
P.s. my mac is m1 but I use dynare’s intel version
