RES: How to update an old GDBServer to implement gdb/mi?

Hello Yao, and thanks for your answer.

I'm not sure if I was clear enough, so I add some more detail: my GDB Server runs on a board with SPARC processor (more specifically, an ERC32), and is installed just after the boot loader and the start of the C runtime. There's no operating system under the GDB Server.

On the gdb "host" side, I already use a GDB built for the sparc target, which works pretty well when debugging by command line or using an old front-end like DDD. But not with Eclipse or any modern front-end - and I assumed this would be due to the lack of support for the MI protocol by my GDBServer.

So, are you saying that the gdb executable should be translating the "MI" commands received by Eclipse CDT and sending them as CLI commands to my board? Who has to "speak" MI? The GDBServer on my board or the gdb executable built for sparc target?

Thanks again for your attention,

Fabrício.

GDBserver doesn't support MI but GDB does.  You can configure and build gdb for sparc target, use this gdb in Eclipse CDT, and connect to your old GDBserver.
