Error: 'make all'

[ycliu1217]

I ran

cp Makefile.config.example Makefile.config
make all

as suggested on the website to complete the installation.
I use Ubuntu 14.04 with CUDA and OpenBlas.

The error messages showed as follows

I only modified Makefile.config.

I googled but there seemed no similar issues.

I have no idea about it.

Can anyone give me some help?
Thanks!

Did you make modifications to the source code?
And can you reformat the comment as it is very difficult to read through.
Add three back-ticks at the beginning and at the end of the error part so that it becomes more readable (back-tick = ``` . Add three of these at the start and at the end)

[ycliu1217]

@IMG-PRCSNG Thanks for you reminding. I added line and back-ticks to separate the error messages.

Well, just in case, you are compiling with a wrong flag to blas.
For using open blas, you must set BLAS := open ( and not OpenBlas ).
Similar errors were encountered in #2348 and #2353.
I am not saying this is the solution, but you can try cleaning your previous build and follow the steps in the referenced issues. Kindly let me know what happens.

[ycliu1217]

@IMG-PRCSNG
I used the method in #2348 .
Input the commands as follows

mkdir build
cd build
cmake ..
make all

The process was done without error.
Then I changed to the caffe folder to execute make all.
But the errors still existed.

And BLAS := OpenBlas was changed to BLAS := open.

If you're using cmake, you don't also use the Makefile (in the root caffe directory). You use one or the other.

Also, please ask this question on the caffe-users list.

Please do not post usage, installation, or modeling questions, or other requests for help to Issues.
Use the caffe-users list instead. This helps developers maintain a clear, uncluttered, and efficient view of the state of Caffe.
