unresolved external symbol in class?

[roccomoretti]

Looks like it's having an issue finding the function std::pair< std::string, std::string > binder::function_arguments_for_lambda( clang::FunctionDecl const *, int) when attempting to link std::string binder::bind_constructor( clang::CXXConstructorDecl const *, std::pair< std::string, std::string > const &, unsigned int, bool, binder::Context &)

Which is odd, as that function should be present with binder/function.cpp ... unless there's an issue with the conversion of int to uint to Windows.

@lyskov I don't think uint is a standard C++ type. Where is the definition of this type supposed to be coming from? I couldn't find a typedef in binder proper, nor does it look like the LLVM headers use/define it. Windows having problems with the uint type might explain the issue.

I do not have Windows machine so i can not replicate this. But it looks like problems with linking, particularly that you might need to alter linking command line and instruct your compiler to link the right libstdc++ (i would guess then one that VC uses)...

[trelau]

hmmm...anything in that error look like a missing library? I can never decipher these things...

I used the /FORCE command to get an executable, and it was able to generate bindings for everything except classes since this error is in the class.obj file.

looping in @csarn since some success has been mentioned in the pull request.

@roccomoretti I converted all uint to unsigned int in my local repo. I'll admit I'm just blindly changing some source code to try and resolve it (I don't have a lot of experience in C++). Thanks for the input. I'll keep working on it.

[trelau]

jeez...when I replaced uint with unsigned int I had inconsistent types in the function_arguments_for_lambda method (one had int and the other had unsigned int)...typo..i'll close the issue

[lyskov]

Wow good find @roccomoretti i totally misread that error message!

[lyskov]

@trelau re unit: the simplest solution to workaround it would probably be to add uint typedef in some of the Binder header and make it conditional for Windows platform with defines. Pull-request doing this will be welcome!
