The problem of Golang runtime-gdb.py

This is a creation in Article, where the information may have evolved or changed.

Problem:

(GDB) source/users/sherlock/documents/go/src/runtime/runtime-gdb.pyloading go Runtime support. Traceback (most recent):  File "/users/sherlock/documents/go/src/runtime/runtime-gdb.py", line 205, in <module>    _rctp_type = Gdb.lookup_type ("struct Runtime.rtype"). Pointer () gdb.error:No struct type named Runtime.rtype.

Solution:

1. Git clone https://github.com/golang/example.git

2. Go test-c in the Stringutil directory.

3.

Gdb-q./stringutil.testreading symbols from./stringutil.test...done. (GDB) source/usr/src/go/src/runtime/runtime-gdb.pyloading go Runtime support. Traceback (most recent):  File "/usr/src/go/src/runtime/runtime-gdb.py", line 205, in <module>    _ Rctp_type = Gdb.lookup_type ("struct Runtime.rtype"). Pointer () gdb.error:No struct type named Runtime.rtype. (GDB) Set pagination off (GDB) set logging oncopying output to gdb.txt. (GDB) Info types# much output (GDB) quit

4. Command line

grep runtime gdb.txt   | grep type;

5. Draw conclusions

6. Modify the runtime-gdb.py No. 205 line rtype Change to _type

Note: My platform is Mac OS X 10.10.3, go1.4.2

Other platforms may not be

struct []*runtime._type;
