Go-ethereum Debug Compilation

When you use Go-ethereum for development, you need to test and debug Geth, because the official default makefile compiled version is an optimized version, regardless of GDB,

or DLV Debugging tools, will appear inconvenient debugging, after their own sorting and groping, to achieve the Go-ethereum debug version of the compilation,

The summary steps are as follows:

0. Use of the official Makefile production environment:

Cd/path/to/go-ethereum

Make Geth

1. Export GO work environment environment variables: Export gobin=/path/to/go-ethereum/build/bin

Export Gopath=/path/to/go-ethereum/build/_workspace

2. Force recompilation

Go install-a-gcflags=all= '-n-l '-v./cmd/geth

3. Compile or download DLV, recommend the use of DLV debugging tools, compared to GDB, DLV for Golang have better support.

DLV exec Geth
