Can not source debug in renderdoc even when I call SetGenerateDebugInfo

[wsyOverflow]

I used to compile shader by glslc with "-g" option, therefore I can debug shader in source level by renderdoc. However, I implement online compile by shaderc and call SetGenerateDebugInfo for copmile option, renderdoc displays "Source debugging unavailabel".

How can I implement same function of "-g" option of glslc in shaderc?
