when I use "make all -j8", occur this errors

[zhengchuansh]

I has install caffe, and successfully run examples .
erros:

Caffe has several dependencies. Check this for more information: http://caffe.berkeleyvision.org/installation.html

[zhengchuansh]

after I install dependencies, then run demo.m, occur this error:

LD_LIBRARY_PATH=/usr/lib/libstdc++.so.6
or check this: kyamagu/mexopencv#45

[zhengchuansh]

and I also has use: sudo ln -sf /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.19 /usr/local/MATLAB/R2011a/bin/glnxa64/libstdc++.so.6, so run successfully.
thank you very much!

[kevinlin311tw]

Hope you are well.
If you got "Warning: Problems with file" when running run_cifar10, make sure you have download the images or check this: #1

[zhengchuansh]

when run demo, I got "Warning: Problems with file" , because we must add "." to img_list.txt. like this "./examples/cvprw15-cifar10/imgs/horse2.jpg" ,then everything will be ok. And I also find if I want to run run_cifar10, I must add path for other functions, such as: path(path,'./matlab/caffe/');

But the result is very strange:
Elapsed time is 0.075924 seconds.
Complete Query [Hamming] 0.08 seconds
query 10000
Warning: Converting non-floating point data to double.

In pdist2 at 219
In precision at 20
In run_cifar10 at 61
Elapsed time is 0.081869 seconds.
Complete Query [Hamming] 0.08 seconds
MAP = 0.105777

MAP should be 0.897373

In analysis folder, binary-train.mat and binary-test.mat, they are all one.
so the result is wrong

[kevinlin311tw]

You didn't get the binary codes. Some suggestions as below:

1. Launch matlab at caffe's root folder, or run startup.m before testing any function.
2. Add "." to train_file_list.txt and test_file_list.txt. For example, "./examples/cvprw15-cifar10/dataset/batch1/4590.jpg"

[zhengchuansh]

I first run startup.m, and delete other inaccurate .mat data, then got the right result.
thank you!

[kevinlin311tw]

Great!!
