error: no member named 'int16' in namespace 'ceres'

[ubuntuslave]

I'm trying to build cyres by going to the source folder and running:

python setup.py build

but I get errors relating to the ceres::int16 data type not existing. Is this a Cython issue with clang on Mac OS X?

What version of ceres-solver are you trying to build with? My hunch is it's related to not having updated cyres to work with the most recent version.

[ubuntuslave]

I home-brewed ceres-solver version 1.10.0. In addition, I'm using Numpy 1.9.2 and cython 0.22. Do you recall which version of ceres-solver worked for you?

[arjun810]

I've got 1.8.0 right now. I think it changed in a recent version of ceres, and it looks like someone actually fixed this in a fork:
PolarNick239@1fb4674

I generally go through and make similar fixes every time I upgrade ceres, but I haven't upgraded recently.

[ubuntuslave]

I fixed this problem by changing the data type from int16 to int32 in a couple of files in the src folder.

In addition. I had to avoid linking to GPU-related libraries that my system doesn't support (for exemple, "cholmod", "camd", "amd", "colamd", "cxsparse") in the setup.py script.

I'm not sure if I should create pull request since this only solves my particular problem. I think a more dynamic setup.py is needed.

I wonder if @PolarNick239 could make a pull request for 1fb4674? That commit fixed this issue for me.

I am sorry, I forgot/not realized to do so. Will do soon (in a couple of days).
