Definition of template class member function specialization doesn't emit symbol unless its unspecialized...
I'm reposting this problem, which I also encountered with Windows10, Visual Studio 2015.
Could someone tell me the recent progress of it?
Look at the following example. https://godbolt.org/g/wUavhy It seems
like for every compiler except Visual Studio it doesn't matter if
unspecialized function definition is outside or inside class. But MSVC
emits symbol for specialization only for variant with #define
INNER_DEFINITION 0. And for me it seems like it shouldn't matter too.
Since this issue results in a linker error it may be quite
counter-inutive to a programmer.

Looks like MSVC bug to me. I imagine, you have unresolved symbols linker error in real life?

yes @SergeyA, I'm trying porting this repo to Windows: github.com/zhangxaochen/surfelmeshing, which produces the same error (I think so)... currently I have to move the non-specialized function body outside the class as a workaround, but wondering if there is a standard solution.

You might try to submit bugreport to MSFT? As an alternative, you might use a non-MSVC compiler for Windows - gcc (through MinGW) or CLang.

I'm voting to close this question as off-topic because it's a question for the MS support team about how they progressed with their bugfixes.

@SergeyA yes gcc should work, but I'm just curious... is inlining the specialized member functions a good way?
