RE: [cdt-debug-dev] MI: obtaining GDB's stderr
|
Hi Derek,
In most cases the process returned by "getGDBProcess" is not a process
that runs gdb. There is a class called Spawner that starts a gdb process
and creates the pipes for stdin, stdout and stderr. The Spawner's native
code is located in the "library" directory of the
org.eclipse.cdt.core.<os> plugins. It may be a bug, I don't know if we
have ever used the error stream from gdb.
It would be very useful if you and other "monitor" users come up with
the requirements on how to improve the support for "monitor" in general.
My personal experience with it is very limited.
Regards,
Mikhail

Subject: [cdt-debug-dev] MI: obtaining GDB's stderr
Hi,
How can I get access to GDB's stderr? I am trying to obtain additional
(error) information that is returned from a "monitor" command.
I am using the following code but reader.ready() always returns false.
MIProcess gdbProcess = miSession.getGDBProcess(); InputStream err =
gdbProcess.getErrorStream(); BufferedReader reader = new
BufferedReader(new InputStreamReader(
err));
String line = null;
try {
while (reader.ready()) {
line = reader.readLine();
errors.add(line) ;
}
reader.close();
} catch (Exception e) {
e.printStackTrace() ;// the reader may throw a NPE.
}
I know that data is being written to stderr - I just can't get it!
TIA
