[Windows] DLL Path and Name

[tqchen]

@hjk41 Is it possible to make the windows dll libmxnet.dll instead of mxnet.dll? Since the later will be used by R libraries.

@yajiedesign

It is also great if we can point the build result path to lib/libmxnet.dll so it is consistent with linux/osx

[hjk41]

ok

@hjk41 Can you share the dll with me? Or can you help test the R package on Windows? I can tell you the steps.

https://github.com/dmlc/mxnet/releases/download/untagged-3801d7b98bea4a33b21c/mxnet_0.9_win64_cpu_only.zip

This is a draft and is very large: ~600MB. I am now working to shrink the
size. Please use it for now and I will post the refined package soon.

I have just compiled a version with statically linked opencv:

https://github.com/dmlc/mxnet/releases/download/untagged-175e0487d0d7aaff577b/mxnet_0.9_win64_cpu_only.7z

Please use this one and see if it works with R.

Thanks @hjk41 The file size is great. Do you think if you can give a script to "INSTALL" the library? I.e. put it in some location and have a script to setup Path automatically

[tqchen]

As far as I understand, mxnet_shell.cmd only works for this command line, but did not setup env for the system

[hjk41]

ok... I can make a installer for this.

I think we like to have the zip version, so advanced user can put things wherever they like and setup path manually. And a additional setup script in the zip to help user to install things when they donnot know what to do

@hjk41 Hi, just a small problem. R on Windows is compiled using sjlj and you are using seh.

Besides, it seems to depend on VCOMP120.dll. (I have really little knowledge about Windows, so I don't know what it is.)

Can you give some instructions on how to compile it on Windows using MinGW-w64?

[tqchen]

@thirdwing The dll might be VS 2013 runtime. The exception handling mechanism should be fine, as we catch most exceptions in the libmxnet.dll and return a 0 in the C API. So exception would not cross the dll boundary

[thirdwing]

After switching to sjlj, we don't need to include libgcc_seh.dll.

[hjk41]

libgcc_seh.dll is the dependency introduced by openblas.

So you are using precompiled openblas? It will be better if you can compile it using sjlj. But it doesn't matter, I think.
