I have been trying to input a character from the keyboard using the simple program shown below, with many different variations, but have had no luck.

The program and error is shown below:
/*
* main.c
*/

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main ()
{
int c;

c = getchar(stdin);

asm ("sld %r1, c");
asm ("halt");
return 0;
}

When the function 'main' is compiled an errer like the one below occurs. Each time it compiles the file after "\\included\\scr\\ is
different even when it is included in the functions 'scr' file


Info: Internal Builder is used for build
"\\xgcc" -O0 -g3 -Wall -c -fmessage-length=0 -o "include\\src\\scanf.o" "..\\include\\src\\scanf.c"
Cannot run program "\xgcc": Launching failed

What am I doing wrong? Any help would be much appreciated.

It's best to ask on the CDT forum: https://www.eclipse.org/forums/eclipse.tools.cdt


It doesn't look like you've configured a toolchain properly. I.e., "\\xgcc" looks kind of bogus to me.

Looking at the embedded assembler code in the snippet, it seems that the poster is attempting a cross-compile, but hides the fact from us.

The code snippet does not make sense, even on bare hardware.
