Answer 1

El compilador es demasiado exigente, por lo que emite advertencias para la aritmética del puntero que implica literales de cadena. Además, probablemente configuró gdb con --enable-werror o -Werror se hereda de alguna parte, por lo que estas advertencias inofensivas se convierten en errores. (Solo mostró los indicadores de configuración para el compilador, no gdb ).

Solución: apague -Werror , o silencie esta advertencia específicamente usando -Wno-string-plus-int (agregue a CFLAGS )

Answer 2

Parece que - habilitable-werror está habilitado de forma predeterminada al compilar gdb-7.6.1 en OSX.

./configure --disable-werror
make

funcionó bien para mí
