Dlib failed to build due to many errors: error C2065 and C2338

[Agustinm28]

I tried to build Dlib on Windows with VS2017 Update2. It failed to build due to many errors: such as error C2065, C2338 or MSB6003. Could you please help take a look at this? Thank you!

Expected Behavior

Build successfully.

A lot of these errors are due to ssize_t being undefined. You can fix this by editing C:\Users\agust\Downloads\dlib-19.22\dlib\external\pybind11\include\pybind11/numpy.h

Find these lines of code near the top of the file after the #include statements:

#if defined(_MSC_VER)
#  pragma warning(push)
#  pragma warning(disable: 4127) // warning C4127: Conditional expression is constant
#endif

Change to:

#if defined(_MSC_VER)
#  pragma warning(push)
#  pragma warning(disable: 4127) // warning C4127: Conditional expression is constant
#include <BaseTsd.h>
typedef SSIZE_T ssize_t;
#endif

This will provide a definition for ssize_t and allow the compiler to continue
I had this problem too. After the change above, dlib built with no issues.

Hope this helps

The better solution might be to use Py_ssize_t instead of ssize_t in numpy.h. (As this is a python only file, there are noch compatability issues with the rest of the library)

Other libraries have faced the same issue: jpype-project/jpype#1009

@davisking can you make new release? Latest release is 3 days before this patch, so it still fails for regular folks who do pip install dlib.

[davisking]

Done :)
