Error when run "deepcl_unittests.exe" on Win7 x64

error code:-1

C++ exception with description "Error getting OpenCL device
 ids: -1" thrown in the test body.

It seems that it can't find my GPU.But other tests can find it. You can see the last part of test log as follows:

Hmmm, I'm going to guess that:

• you have two OpenCL platforms
• the first one doesnt have a GPU

I've pushed some changes in https://github.com/hughperkins/DeepCL/commit/c87dfce77c628549de92e78bdcea6c3ec1899fb9 , which should hopefully address this issue. Can you pull down the latest changes, and retry please?

[aqua7regia]

Thx for your reply. I have pull the latest code, but I can't build the project in VS2010. The error was found in binary zip files. So, would you update those files on http://deepcl.hughperkins.com/Downloads/ please? I'm still searching the reason of build failure in VS2010. Thanks a lot.

[hughperkins]

For the vs2010 build failure, please give me the error you are seeing, or the entire build log (via eg a github gist), or a screenshot of the error you are seeing.

For the built zip file, you can find it for win64 at: http://deepcl.hughperkins.com/Downloads/deepcl-win64-v8.2.0alpha1.zip

[aqua7regia]

I use the new built file to run unit test. Now all tests have passed!

I may mistake some config in cmake. So I re-config and re-generate projects. Now all projects can build successfully in VS2010.

The problem has been solved.

Thanks~

Ok, great!
