Build fails with missing 'pthread.h' in Caffe.vcxproj

[jpsacha]

I am building using VS12 on Windows 7 following instructions in readme (after correction for #18). It goes for a while fine till it stop on error in Caffe.vcxproj. The actual error message is in
Caffe-prefix\src\Caffe-build\CMakeFiles\CMakeError.log:

Determining if the include file pthread.h exists failed with the following output:

...

D:\build\Caffe-prefix\src\Caffe-build\CMakeFiles\CMakeTmp\CheckIncludeFile.c(1): fatal error C1083: 
   Cannot open include file: 'pthread.h': No such file or directory [D:\build\Caffe-prefix\src\Caffe-build\CMakeFiles\CMakeTmp\cmTC_12ae6.vcxproj]

Look that I need to add pthreads library somewhere. What is the proper way to to it?

Never seen that one. By VS12 you mean 2013 right? You should not need to add pthreads but use Win32 Threads instead. The threads in caffe are checked here:

See cmake doc for FindThreads:

Thanks for the hint. It let me eventually realize that I was looking not at the cause of the problem but the last reported error that was not important.

Error above that one was

Could not find PROTOBUF Compiler

Very similar to situation described in Issue #17, so I followed advise there. Had to edit Caffe-prefix\src\Caffe-build\CMakeCache.txt and add location for PROTOBUF_PROTOC_EXECUTABLE and PROTOBUF_LIBRARY that are located in install/vsprojects/Release of the build directory, and PROTOBUF_LIBRARY_DEBUG located in install/vsprojects/Debug. It is important to have both Release and Debug defined to avoid linking errors in the default build.

I followed the instruction for using CMake but I got the same problem...
