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 past this issue on Mojave by thinning the app. GDB does not understand universal binaries. So if file myapp tells you myapp is a universal binary, try this:

lipo -thin x86_64 -output myapp-x86_64 myapp

And then

gdb myapp-x86_64
