Go (Debugging with GDB)
Next: Objective-C, Previous: D, Up: Supported Languages [Contents][Index]
15.4.3 Go
GDB can be used to debug programs written in Go and compiled with gccgo
or 6g
compilers.
Here is a summary of the Go-specific features and restrictions:
The current Go package
The name of the current package does not need to be specified when specifying global variables and functions.
For example, given the program:
package main var myglob = "Shall we?" func main () { // ... }
When stopped inside main
either of these work:
(gdb) p myglob (gdb) p main.myglob
Builtin Go types
The string
type is recognized by GDB and is printed as a string.
Builtin Go functions
The GDB expression parser recognizes the unsafe.Sizeof
function and handles it internally.
Restrictions on Go expressions
All Go operators are supported except &^
. The Go _
“blank identifier” is not supported. Automatic dereferencing of pointers is not supported.
