error: linking with `link.exe` failed: exit code: 1120 about shaderc-rs

The Vulkan Configurator GUI is something new that I haven't tried out. I typically use CLI environment variables to force layers on. I think you can use VK_LAYER_PATH to point to the layer installation location (might be unnecessary if you installed it to a standard location) and then use VK_INSTANCE_LAYERS to enable certain layers. You may also want to set VK_LOADER_DEBUG=all to see verbose output from Vulkan loader to verify things work. You can find more details here: https://github.com/KhronosGroup/Vulkan-Loader/blob/master/loader/LoaderAndLayerInterface.md#table-of-debug-environment-variables

Hi @mildcwen, could you provide more details? Like the verbose output of failing to compile your project?

[mildcwen]

@antiagainst thanks for reply. I'm studying for Vulkan and I want use vk-shader-macros , but couldn't compile. So i new project just use shaderc. and copy it's Example Only! and error message is too long ....
-------------------
I have build from Source again. ..and again.....
error LNK2019( the major message)

= note: Non-UTF-8 output: libshaderc-37bb496e57e67982.rlib(shaderc-37bb496e57e67982.shaderc.5iq9nx3y-cgu.0.rcgu.o) : error LNK2019: \xce\xde\xb7\xa8\xbd\xe2\xce\xf6\xb5\xc4\xcd\xe2\xb2\xbf\xb7\xfb\xba\xc5

There are some similarities to Issues #80 but don't have tip information..
--------Maybe I only selected to upload the ".spv" file....sad!

Hi @mildcwen, the error looks like something related to language/locale settings in Rust itself. See rust-lang/rust#35785. I'm using English as my primary language on Windows. It works fine for me to cargo test in a newly checked out vk-shader-macros.

Besides, you can try to use v0.7.0, which can detect Vulkan SDK and use the shaderc libraries there directly (if you have VULKAN_SDK environment set) so you don't need to manually download and specify the shaderc location.

@antiagainst first, I've installed Vulkan SDK, and get the same error as before.
and i follow the answer of 「crlf0710 」, I modify VS'LANG to English,
then appear this

= note: libshaderc-37bb496e57e67982.rlib(shaderc-37bb496e57e67982.shaderc.5iq9nx3y-cgu.0.rcgu.o) : error LNK2019: unresolved external symbol shaderc_compiler_initialize referenced in function _ZN7shaderc8Compiler3new17ha016f1c6249e5b8aE

The next I uninstall [Visual C++ 2015, 2013, VS2015 X64 Native Tools Command(VC++ Build Tools)],just stay 2017 (it's only English )on PC.
Finally Error.

error LNK2019: unresolved external symbol shaderc_parse_version_profile referenced in function _ZN7shaderc21parse_version_profile17hff3b319b261982f0E

---

I look the message found still use SHADERC_LIB_DIR, then delete it and restart PC, and compile ,all Fine.

@antiagainst , Thank you very much. I've solved this trouble...ha-ha.
I think install Vulkan SDK is much easier than Build from google-shaderc. and thank you again...
(So maybe could write in README? there are too issue since build source...)

please close this issue.
Thank you again for your help!
大佬....感謝!

@antiagainst
May I ask you another question? (....I konw it's not relevant.., and I promise this is last one comment.)
I've installed Vulkan SDK. ,but since Coding in Rust instead of c++..
Error: Layer specified does not exist .So i want to know how do you call the sdk..
Because i want to use VkLayer_khronos_validation.dll etc..i'm not sure which is ...
I just want to enable Validation Layer to debug with validation layer.(before not use...)

--
I heard this also could debug..But I can't use it

[mildcwen]

There's no need to reply.
Since it's myself problem ..I'm not going to comment any more

Thank you very much for your help!
