Re: [go-nuts] How to debug internal package by gdb?

[Zhuo Meng]

I've figured that out

Turns out it's path is starts with vendor, not internal

(gdb) info functions
to show internal package file path

File 
/root/godev/src/vendor/golang_org/x/crypto/chacha20poly1305/internal/chacha20/chacha_arm64.s:
void 
vendor/golang_org/x/crypto/chacha20poly1305/internal/chacha20.block(void);
void 
vendor/golang_org/x/crypto/chacha20poly1305/internal/chacha20.block4(void);

(gdb) b vendor/golang_org/x/crypto/chacha20poly1305/internal/chacha20.block4
Breakpoint 1 at 0xe0840

@Ian Thanks for helping

There is nothing special about internal packages with regard to
debugging.  Are you completely sure that the package was imported by
your program?  Are you sure that the functions on which you are trying
to set a breakpoint are called?

[go-nuts] How to debug internal package by gdb?

[Zhuo Meng]

Hi, everyone

I'm trying to write some internal package , but when I try to follow the 
code line by line using gdb.
I found all the internal package are missing from breakpoint setting.

How can I break on internal package?
