mingw-caffe: A Shell repository from lemonsqueeze

Binary packages: Releases

These files can be used to build a minimal cpu-only caffe package for msys2 / mingw-w64.
Build pulls latest caffe sources from git (master branch).

To build, run an MSYS2 shell, install dependencies:

pacman -S git make patch diffutils

# 32-bit build:
pacman -S mingw32/mingw-w64-i686-tools-git          # gendef, dlltool
pacman -S mingw32/mingw-w64-i686-gcc
pacman -S mingw32/mingw-w64-i686-boost
pacman -S mingw32/mingw-w64-i686-protobuf-c
pacman -S mingw32/mingw-w64-i686-gflags
pacman -S mingw32/mingw-w64-i686-glog
pacman -S mingw32/mingw-w64-i686-hdf5
pacman -S mingw32/mingw-w64-i686-openblas

# 64-bit build:
pacman -S mingw64/mingw-w64-x86_64-tools-git        # gendef, dlltool
pacman -S mingw64/mingw-w64-x86_64-gcc
pacman -S mingw64/mingw-w64-x86_64-boost
pacman -S mingw64/mingw-w64-x86_64-protobuf-c
pacman -S mingw64/mingw-w64-x86_64-gflags
pacman -S mingw64/mingw-w64-x86_64-glog
pacman -S mingw64/mingw-w64-x86_64-hdf5
pacman -S mingw64/mingw-w64-x86_64-openblas

Navigate to mingw-w64-caffe directory and run makepkg-mingw.

The MINGW_INSTALLS variable can be set to mingw64 if you only want to build the win64 version,
or mingw32 if you only want to build the win32 version.

To install the built package on your system:

pacman -U *.pkg.tar.xz

Issues

Linking with caffe binary package fails.
Most likely boost / glog / gflags packages have been updated and caffe needs to be rebuilt.
Caffe fails to compile: error near STRICT in src/caffe/proto/caffe.pb.h
A header in current boost package is messed up, #defines STRICT when it really shouldn't. Try this:
```
patch -d/ -p0 < boost_header_fix_mingw32.patch
patch -d/ -p0 < boost_header_fix_mingw64.patch
```
When linking statically, caffe fails with 'Unknown layer type: Input'
Currently you need this for static link to work:
```
-Wl,--whole-archive -l:libcaffe.a -Wl,--no-whole-archive
```
or modify caffe to only pull in the layers you need (see 'mini' branch for example).
Can't link statically, libglog.a and libprotobuf.a are missing.
Need glog / protobuf packages with static libraries.

Based on DavidEGrayson's mingw-packages-deg

Fixed dll and 'Failed to parse NetParameter file' issues.

No extensive testing, loading and forwarding trained networks works though.
