Having
GDB infer the source language
To have
GDB set the working language automatically, use ‘set
language local’
or ‘set language auto’.
GDB then infers the working language. That is, when your program stops
in a frame (usually by encountering a breakpoint), GDB sets the working
language to the language recorded for the function in that frame. If the
language for a frame is unknown (that is, if the function or block corresponding
to the frame was defined in a source file that does not have a recognized
extension), the current working language is not changed, and GDB issues
a warning.
This may not seem necessary
for most programs, which are written entirely in one source language. However,
program modules and libraries written in one source language can be used
by a main program written in a different source language. Using ‘set
language auto’
in this case frees you from having to set the working language manually.
