Find which dependency uses cgo

Question

I'm getting the following error when I compile my Go binary locally and then run it on my docker container:

my-server: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by my-server)
my-server: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by my-server)

Everything works fine if I set CGO_ENABLED=0 when compiling. None of my code uses glibc, so I'm just curious which of my dependencies is pulling it in. Is there any way to query which dependency requires this?

Answer 1

which of my dependencies is pulling it in

Running LD_DEBUG=files my-server |& grep 'needed by' will produce lines similar to:

   2310307:     file=libtinfo.so.6 [0];  needed by ... [0]
   2310307:     file=libc.so.6 [0];  needed by ... [0]

which should answer your question.
