Caffe Windows Build failed when CMAKE_BUILD_SHARED_LIBS=1

[Paul Delamusica]

I am building caffe on Windows 7 using VC 2013 according to the instructions in https://github.com/BVLC/caffe/blob/windows/README.md

If I set CMAKE_BUILD_SHARED_LIBS=1, I got the following message and the build aborts. 

.....

"c:\projects\caffe\build\ALL_BUILD.vcxproj" (default target) (1) ->

"C:\projects\caffe\build\tools\upgrade_solver_proto_text.vcxproj" (default targ

et) (21) ->

Use the ninja generator. The vs generator is known mot to work for this configuration.

Thanks!

I downloaded ninja, put the *.exe into the search path, and re-run the build script. It seems the C compiler isn't correctly identified. Is MSVC 18 somewhere hard wired?

Here is the full error message:

Hi,

Where do we find this search path. I downloaded ninja but not able to figure out how to use it for caffe installation on windows10 with cuda8.0

Please help me out

Thanks

Hi Paul, 

Were you able to solve this problem? I'm also getting the same error when I try to build Caffe in Windows 10. If you found the solution please be kind enough to post here. 

Thanks!
