Trouble linking pre-compiled lib from AppVeyor (VS 2017)

[Crisspl]

I'm having trouble linking shaderc_combined.lib to our project on MSVC x64 (Visual Studio 2017). I got the binary from AppVeyor as you suggested in README. However I'm getting linker errors about stuff from shaderc.h (interestingly all c++-linkage stuff [things from shaderc.hpp] seems to be linked perfectly fine as I don't get any errors about those).

I tried to link pre-compiled binary because I got an impression that your build system is designed strictly for Linux. Maybe I'll try to build it myself tomorrow, but I feel it's not going to be easy.

I'm currently having this exact issue ("unresolved external symbol shaderc_compiler_initialize" & friends) and the fact that this issue was closed without comment troubles me.

shaderc worked fine on macOS & Linux but for some reason getting it to work on Windows eludes me. Maybe that's just a testament to how stupid the OS is.

Edit: I was able to fix it by setting VULKAN_SDK instead of trying to manually set the link search path, which AFAIK is an environment variable of the bindings I'm using and not the shaderc library itself. Just in case anyone else comes across this...

@LoganDark What do you mean VULKAN_SDK? I tried linking to the include directory via my project properties which allows myself to code and include the shaderc.hpp file... but compiling I have this same issue... So what your saying is to setup that variable name in my laptop's environment variables and have it go to the directory of what now? a .lib or the include?

Assuming Windows, the Vulkan SDK is usually installed to somewhere like C:\VulkanSDK\1.3.204.1, which is where I pointed my VULKAN_SDK to.

Note that normally you can set environment variables in your IDE (or in PowerShell via New-Item), but if you do it in the system environment variables configuration (i.e. the one you will find in the Start menu), you'll have to log out and log back in for it to take effect.

@LoganDark I'm already using Vulkan and have been for a while... I'm using the msvc's compiler built into Visual Studio. I also have the environment variable already setup, yet I continue to get the error. In VS, I setup the c++ include link to the include folder and the linker library set to the lib folder. Yet it still does not work.

Can't help you there unfortunately, since I am using the Rust shaderc crate. Sorry :(
