No debugging symbols found in Visual Studio when built C program with Bazel(Windows)

[Uma Patil]

I have simple C program. I want to build and debug C program using Bazel on Windows within Visual Studio Code . But getting error as: (No debugging symbols found in bazel-bin/examples/application/application). How can I get Symbols.

 I have cc_binary :

cc_bin`enter code here`ary( name = "main", srcs = glob(["*.c"]), deps = [ "//examples/sub_main", ], visibility = ["//visibility:public"], )

I'm using following command to build and debug.

bazel build --compilation_mode=dbg //examples/main --strip=never 

gdb bazel-bin/examples/main/main 

But I'm getting error as: (No debugging symbols found in bazel-bin/examples/application/application) Even after using compilation_mode ad dbg why is it not generating any Symbols? How can I get symbols to debug?

Am I missing something here? Please let me know

Have you tried manually adding --copt=/Z7?

[Konstantin]

If you use 

     load("@rules_cc//cc:defs.bzl", "cc_binary")

like in this example on Windows, then it definitely uses `/Z7` flag (see here). 

I just tried it to be sure and the binary I got does contain debug symbols.

You can use Bazel command line flag `--subcommands=pretty_print` to see which exactly options it uses on the compiler command line.

Hi Konstantin,

Thank you for your response. In my case I had "build --incompatible_enable_cc_toolchain_resolution" in my .bazelrc file. I'm not sure exactly, but when i removed this it was generating debugging symbols. Let me know if you have any idea why was --incompatible... flag causing issue to create sybols.
