manual build with -DDLIB_NO_GUI_SUPPORT=0 giving weird bug #10

Open nateGeorge opened 8 years ago

nateGeorge commented 8 years ago

For some reason when I manually build, it's giving a weird bug. 

Boost.Python.ArgumentError: Python argument types in
    simple_object_detector.save(simple_object_detector, str)
did not match C++ signature:
    save(dlib::simple_object_detector_py, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > detector_output_filename)

I'm not sure if it's something about my local env variables or what. When I do

conda install -c menpo dlib=18.18

It works fine, but I want to have the GUI enabled, so I'm trying to do a custom build.

What operating system?

nateGeorge commented 8 years ago

Ubuntu 16.04 LTS 64bit. The error I posted is from trying to save a detector object.

patricksnape commented 8 years ago

Right, so that is likely due to the upgrade to GCC 5.x. It may have something to do with the slightly old build of Boost that I am using here. Likely Boost > 1.59 is required for C++11 builds.

nateGeorge commented 8 years ago

Hmm, so I should try to build with an older boost somehow? It says it is installing boost 1.59 when it is installing dlib. I also installed 1.61 to see if it helped, but I don't know which boost it's actually using.

patricksnape commented 8 years ago

I would build with a newer boost. I think conda-forge has a newer boost. Maybe if you try adding conda-forge to your .condarc channels list and then updating the boost in the recipe to 1.61?

nateGeorge commented 8 years ago

Alright, I'll see if I can figure that out. Thanks!

patricksnape commented 8 years ago

@nateGeorge Did you ever get this working?

nateGeorge commented 8 years ago

Nope, I never did. Just using python2 with dlib for the GUI.
