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

[zhengchuansh]

I has install caffe, and successfully run examples . erros: head lines: make: /usr/local/MATLAB/R2012a/bin/mexext: Command not found g++ src/caffe/net.cpp -pthread -fPIC -DNDEBUG -O2 -DUSE_MKL -I/usr/include/python2.7 -I/usr/lib/python2.7/dist-packages/numpy/core/include -I/usr/local/include -I.build_release/src -I./src -I./include -I/usr/local/cuda/include -I/opt/intel/mkl/include -Wall -Wno-sign-compare -c -o .build_release/src/caffe/net.o 2> .build_release/src/caffe/net.o.warnings.txt \ || (cat .build_release/src/caffe/net.o.warnings.txt; exit 1)

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: https://github.com/kyamagu/mexopencv/issues/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: https://github.com/kevinlin311tw/caffe-cvprw15/issues/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!!
