使用GDB进行Golang调试？

Question

I got 2 questions about GDB + golang?

1) Go build GCC flags 

when I run "go build" , which gcc flags do the Go builder use to build a program? The build value is same as the "GOGCCFLAGS" set in the go envionment?

GOGCCFLAGS="-fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fno-common"

because I don't see any "-g" or "-g3" flags for adding code symbol. If yes, how could the symbol table be compiled ?

2) How to print a value in GDB I followed the tutorial here GDB debug go tutorial, but it seems the value is not what I set.

By the way, I noticed there is a post about it gdb debug go However, doesn't work for me either.

Answer 1

Go does not work well with GDB and one of the known problems is the printing of values.
