gdb 8.2 can't recognized executable file on macOS Mojave 10.14

Question

I get gdb by brew install gdb.

The source file content is:

#include 
int main(){
    int a = 10;
    for(int i = 0; i<          


        

Answer 1

I got gdb working on Mojave by:

a) getting the latest gdb source archive (at time of writing, ftp://sourceware.org/pub/gdb/snapshots/current/gdb-weekly-8.2.50.20190212.tar.xz) - amongst other things, it adds handling for recognizing executables on Mac.

b) build gdb. I got errors for variable shadowing in darwin-nat.c so I edited the file and rebuilt.

c) follow steps in https://forward-in-code.blogspot.com/2018/11/mojave-vs-gdb.html

Voila.
