MSVC 2015U3 compile error in tvec4<T, P>::tvec4(ctor)

[ma30002000]

When updating GLM from 0.9.7.6 to 0.9.8.1, the following compile error occurs in MSVC 2015U3:

Adding a default ctor call for all element fixes the issue:

You don't need to initialize all members, just one will suffice.

This issue should be fixed in GLM 0.9.8 and master branches.

Thanks for reporting,

Unfortunately, this issue is still there - the referenced commit only fixes #555, but not this ticket.

[ma30002000]

Could you please reopen the issue?

[Groovounet]

Could you use #define GLM_FORCE_MESSAGES, build and copy paste the information GLM returns?
I couldn't repro.

Thanks,
Christophe

[Groovounet]

Do you have a simple code sample to repro?

[Groovounet]

How do you get GLM: C++11? Visual C++ 2015 is not fully C++11 compatible and should return C++0x.

[Groovounet]

This issue should be fixed in GLM 0.9.8 and master branches.

I think you are using GLM_FORCE_CXX11 in your code with Visual C++ however Visual C++ doesn't fully support C++11.

By default GLM will automatically detect the compiler and its version to use only the feature set supported by the compiler. Using GLM_FORCE_CXX11, you override this system to use the C++11 features.
