How can I compile mex file in SPM12 on macos Monterey?

I wonder how can I fix the error below.

“Error using file2mat (line 16)

file2mat.c not compiled - see Makefile”

Also when I try to compile the mex, I met the error below.

mex -O -largeArrayDims -c spm_vol_utils.c -DSPM_UNSIGNED_CHAR

make: mex: No such file or directory

make: *** [utils_uchar.mexmaci64.o] Error 1

I cannot directly answer your question since I also am not able to use spm on Mac OS Monterey but if you do not get any answers here, there may be an answer on the spm mailinglist in the future (https://www.fil.ion.ucl.ac.uk/spm/support/) - hopefully.

First of all, make sure that you can run "mex" in the command line in Matlab.

And then, just navigate to the folder, for example, ~/MatLab_ToolBox/SPM/***, and then run "mex file2mat.c" in the command line.

Warnings may be generated. But it really works.

Hi, I met the similar Q. I solved it as followings:

1. make sure you could run "mex -setup". 2. if not, please download the Xcode in Appstore, and open it to make the settings (default). 3. if yes, using the Finder to find the file2mat.c. 4. Then paste the path of folders (contains the file2mat.c) in matlab (see below).

5. after located at this folder (contains the file2mat.c), run "mex fild2mat.c".
