While i debuged the application in windows that use emacs, the buffer of emacs can't get the output,but in system, everything is ok. I don't know where the error is in me or the emacs.
in windows , prommpt can get the output like this:
and in emacs ,gdb buffer like this:
Here is the application, i download from sqlite site,web address http://www.sqlite.org/2014/sqlite-amalgamation-3080403.zip .In windows ,i compiled it using mingw,
using "gcc -g -o sqlite3 shell.c sqlite3.c" to build sqlite3.exe
I tried other app, source code:
#include <stdio.h>
typedef struct {
float a;
float b;
} substruct;
struct {
int i;
substruct r;
} c;
myproc(n)
{
int p;
p = 2*n;
printf("Two times %d is %d\n", n, p);
}
main() {
int n = 4;
int m[10] = {0,1,4,9,16,25,36,49,64,81};
n = 5;
myproc(n);
c.i = 1;
c.r.a = 0.5;
c.r.b = 0.25;
}
saved it to test.c,build by gcc -o test test.c -g
in windows and emacs gdb all can get the output "Two times 5 is 10"
so i think the problem in emacs,but i have not enough time to read the source code......
help me

Hi List:
While i debuged application in windows that use emacs, the buffer of gdb can't get the output,but everything is ok while gdb run in windows by direct running. I don't know where the problem is, in me or the emacs.
in windows , prommpt can get the output like this:
and in emacs ,gdb buffer like this:
Here is the application which i debuged, download from sqlite site, web address http://www.sqlite.org/2014/sqlite-amalgamation-3080403.zip .In windows ,i compiled it using mingw,
using "gcc -g -o sqlite3 shell.c sqlite3.c" to build sqlite3.exe
I tried another app, source code:
-----------------------
#include <stdio.h>
typedef struct {
float a;
float b;
} substruct;
struct {
int i;
substruct r;
} c;
myproc(n)
{
int p;
p = 2*n;
printf("Two times %d is %d\n", n, p);
}
main() {
int n = 4;
int m[10] = {0,1,4,9,16,25,36,49,64,81};
n = 5;
myproc(n);
c.i = 1;
c.r.a = 0.5;
c.r.b = 0.25;
}
----------------
saved it to test.c,build by "gcc -o test test.c -g"
in windows and emacs gdb all can get the output "Two times 5 is 10"
so i think the problem in emacs, does anyone know where is?

Try adding
fflush (stdout);
after each printf call. This might well be a buffering issue.
