Issue when compile

Hi,
I tried to compile your code using Ubuntu 14.04 with matlab 2014b I got mistakes:

gpml toolbox is compiled

Do you have any idea how to solve that?

@zizhaozhang
This looks like a problem in compiling the lbfgs-b module of GPML toolbox. You probably can find some useful information by referring to the README file of the GPML toolbox.

Anyway, it is not critical if you still cannot solve problem. You can just comment out the code for compiling lbfgs-b in ./gp-general/gp_setup.m and in ./dependency/compile_dependency.m

The code will automatically try other solvers (e.g., the LBFGS solver in minFunc, and the minimize toolbox) if lbfgs-b solver doesn't exist.

I probably will also disable lbfgs-b compilation in the next commit, since several people met problems here.

Thanks for your quick response. Another issue is that I follow the instructions and it automatically download some models which includes model_svm_struct and model_svm_linear. However the data inside (e.g., categ_list.mat classifier) has 0 size (file exists but with 0 size). The data in subfolder "cnn" looks fine. Could also let me know the solutions. Thanks!

Oops ... There is a wrong link in get_voc_2007.sh
I corrected in the latest commit.
Thanks for pointing it out!

Thanks you! Yuting
