HI. I'm new on forum.
Ok, I want to compile my first helloworld fo tv. I have downloaded VDLinux-armv7a8-toolchain-lite from samsung server and tried to compile this code:
Code: Select all
#include <stdio.h>
int main(void) {
printf("Hello world\n");
return (0);
gedit }
Code: Select all
arm-v7a8-linux-gnueabi-gcc -mglibc hello.c -o hellocs
then copied hellocs to tv, make chmod +x hellocs and run it.
And I have got: "Segmentation fault".
Need help guys.
Same shit happening when i try to load mc.

First of all you lied. This code doesn't compile:
Code: Select all
#include <stdio.h>
int main(void) {
printf("Hello world\n");
return (0);
gedit }
Second skip "-mglibc". I never used this flag

It's just copy-paste lag.
I tried both:
Code: Select all
arm-v7a15v3r1-linux-gnueabi-gcc -static hello.c -o hello
and
Code: Select all
arm-v7a15v3r1-linux-gnueabi-gcc hello.c -o hello
and I got:
Code: Select all
; Attributes: bp-based frame
EXPORT main
main
STMFD SP!, {R11,LR}
ADD R11, SP, #4
MOV R0, aHelloWorld ; s
BL puts
MOV R3, #0
MOV R0, R3
LDMFD SP!, {R11,PC}
; End of function main
All fine, but I don't know what about is __imp_puts contain right address...

On what "machine" are you compiling it ?
Do our patches run on your TV?
