Compilation error when trying mnist and fcn

[xjtuljy]

Hi, @terrychenism , thank you very much for providing us this windows caffe which can do fcn. I succeeded in compiling the caffe.cpp, but got errors when I tried to either compile FCN.cpp and convert_mnist_data.cpp, from the examples, could anyone suggest me the reason? I am quite new to caffe and hopefully someone could help. Thank you!

here is the error when compiling FCN.cpp in /examples/fcn/:

here is the error when compiling convert_mnist_data.cpp in /examples/mnist/:

[terrychenism]

what kind of system do you use? windows or linux? This fcn branch only support windows.

Thanks for your reply @terrychenism . I downloaded the 'fcn' branch. I am using windows 7 64-bit, visual studio 2012, and CUDA 6.5. I didn't do any modifications except for resetting the 3rd party path in the project properties.

I tried to build these two which failed:
#include "../examples/fcn/FCN.cpp;
and
#include "../examples/mnist/convert_mnist_data.cpp;

but /tool/caffe.cpp can be built successfully.

And I noticed that "tools/train_net.cpp" and "tools/test_net.cpp" are not completed, while in the readme.md, train_net.cpp is suggested to be built, which is confusing somehow. Did I do anything wrong or downloaded the wrong version?

Thank you.

Please do not use "tools/train_net.cpp" and "tools/test_net.cpp", cuz "caffe.cpp" contain train and test function. Also, "fcn.cpp" should be work for this FCN branch. I didn't check "convert_mnist_data.cpp" for this branch, sorry about that.

Thanks Terry. I tried to debug the FCN.cpp and then it can be built:

1. #include < direct.h >
2. replace Caffe::set_phase(Caffe::TEST); with TEST;
3. Net < float > caffe_test_net(argv[2],caffe::TEST);

From the code, it seems that this FCN.cpp is only used for testing, but there is neither trained fcn-8s-pascal.caffemodel.caffemodel nor fcn-8s-pascal-deploy.prototxt existing in the ../examples/fcn folder.

Did I miss anything?
