Permission Denied when compile Caffe by "make all"

[Steve Lu]

Hi,

When I was compiling Caffe with Matlab interface by make all, I got the following wrong message at the beginning:

make: execvp: /usr/local/MATLAB/R2014a: Permission denied

I modified line 40-43 of the file Makefile.config, which is actually uncomment the third line to enable the Matlab directory.

# This is required only if you will compile the matlab interface.
# MATLAB directory should contain the mex binary in /bin.
MATLAB_DIR := /usr/local/MATLAB/R2014a
# MATLAB_DIR := /Applications/MATLAB_R2012b.app

If I comment the third line, the make all process works.

The platform is Ubuntu 14.04. Could you please advise me any solution to this? Thanks!

Have you tried with 'sudo make all' instead of 'make all' ?

[Steve Lu]

Yes, I tried, but failed. I also found that if I make all the Caffe without this line in Makefile.config (which runs correctly) and after the compilation, I still cannot compile Matlab wrapper by make matcaffe. Thanks!

I have the same problem as Steve Lu ......

Did anyone solve this problem?

Hey,

I had the same problem and it seems that something in the cmake files is wrong.
I changed the shell for compilation to /bin/bash and it showed 'XX is a directory' instead of 'Permission denied'.
Use 'make SHELL=/bin/bash all' for that.
If you're facing the 'XX is a directory' problem than proceed as follows:

- To fix the issue you have to change the 'build.make' file in 'BUILD_DIR/matlab/CMakeFiles/matlab.dir/'.
- Search for '/usr/local/MATLAB/R2014a' and replace it with' /usr/local/MATLAB/R2014a/bin/mex'
- Now rerun 'make all' again and everything should be fine.

Good luck

Hi Fabian,

When I try to do make SHELL =/bin/bash all, I get:

make: *** empty variable name.  Stop.

I run this command from the caffe folder.

I'm not sure what I'm doing wrong.

Also, I am new to Caffe, so when I go to install the matlab interface, do I do:

make matcaffe
make all

or

make all matcaffe

or

make all
make matcaffe

? Does it matter?

where can I find the path BUILD_DIR/matlab/CMakeFiles/

matlab.dir

I found that this happens when there is an extra space after the matlab path in the Makefile.config file.

Yes that's right. Thanks Yang you saved much of my time!

Yes, you are right! Thank you for saving my time!!

There should be no extra space at the end of MATLAB_DIR := /usr/local/MATLAB/R2014a.
