clang-build.ps1 vcpkg include for compile_commands.json

[IbrahimHindawi]

Hello, Thanks for the awesome tool! I'm using clang-build.ps1 -export-json command line to generate compile_commands.json for neovim lsp and it works fine except that it doesn't detect vcpkg so I had to manually include the vcpkg path to the compile_commands.json: -I\"C:\devel\vcpkg\installed\x64-windows\include\" Can we please have an option to force it to include the vcpkg include path if vcpkg is present on the system? Thank you.

Hi @IbrahimHindawi,

Thank you for reporting this issue

I have tested this case and I found in compile_commands.json a relative path to the needed library. If you export compilation database from extension Clang Power Tools you will find the absolute path in output log Do you find a problem in using a relative path, or maybe you do not find any reference to your library in compile_commands.json?

Can you give us a test project to reproduce the problem?

Kind regards, Marina

@mariru27 Thank you for your reply.

Relative paths to libraries are not a problem, my only problem is the lack of inclusion of the absolute path to vcpkg's include directories: -I\"C:\devel\vcpkg\installed\x64-windows\include\" into the compile_commands.json. Maybe I missed it?

I am currently using Clang Power Tools script in this project: https://github.com/IbrahimHindawi/cgfx. I have made a workaround to add the absolute path of the vcpkg include directories to the compile_commands.json using this python script: https://github.com/IbrahimHindawi/cgfx/blob/main/scripts/finalize.py.

I only need that since NeoVim doesn't understand what vcpkg integrate install is like Visual Studio, so I have to force it to look in the vcpkg include dir. Let me know if you run into any issues executing the scripts\bbuild.bat command.

Best regards, Ibrahim

@IbrahimHindawi, thank you for giving detailed instructions on how to reproduce the problem

After testing this problem I will return to you with an updated status of this issue. (This will take some time, because we have some tasks to complete first)

Kind regards, Marina

@mariru27 No problem, I already have a temporary fix! Thank you very much. Here is some extra information just for clarification: Here is the Clang Power Tools json file output:

The only difference is the last include of the "command" item.

Hi @IbrahimHindawi,

Do you have Use Vcpkg active?

Go to Project (cgfx) -> Properties:

Kind regards, Marina

[IbrahimHindawi]

Thank you! Didn't know I had to activate that. Closing Issue.
