Linker script not working? - c

Question

I have a very simple program (simple.c):
#include <stdio.h>
int main(){
int a = 4;
return 0;
}
I am trying to use a the following linker script (MEMORY):
MEMORY
{
m_text : ORIGIN = 0x0000000000400000, LENGTH = 0x0001FBF0
m_data : ORIGIN = 0x0000000000600000, LENGTH = 0x00004000
}
SECTIONS
{
.text :
{
*(.text) /* Program Code */
} > m_text
.data : { *(.data) } > m_data
.bss : { *(.bss) } > m_data
}
I am using following commands to compile and link:
gcc -c simple.c
ld -T MEMORY -o simple -dynamic-linker /lib64/ld-linux-x86-64.so.2 /usr/lib/x86_64-linux-gnu/crt1.o /usr/lib/x86_64-linux-gnu/crti.o /usr/lib/x86_64-linux-gnu/crtn.o simple.o
I am getting the following ERROR:
ld: /usr/lib/debug/usr/lib/x86_64-linux-gnu/crt1.o(.debug_info): relocation 0 has invalid symbol index 11
.
.
.
ld: /usr/lib/debug/usr/lib/x86_64-linux-gnu/crt1.o(.debug_line): relocation 0 has invalid symbol index 2
/usr/lib/x86_64-linux-gnu/crt1.o: In function `_start':

/usr/lib/x86_64-linux-gnu/crt1.o: In function `_start':

/usr/lib/x86_64-linux-gnu/crt1.o: In function `_start':
(.text+0x25): undefined reference to `__libc_start_main'
simple.o: In function `main':
simple.c:(.text+0xa): undefined reference to `puts'
If I try to use :
ld -T MEMORY4 -o simple -dynamic-linker /lib64/ld-linux-x86-64.so.2 /usr/lib/x86_64-linux-gnu/crt1.o /usr/lib/x86_64-linux-gnu/crti.o /usr/lib/x86_64-linux-gnu/crtn.o simple.o -lc
It gives the ERROR
ld: cannot find -lc
Any suggestions? All I want to do is place my simple.c into some different memory region then default.

There are a couple of problems, but the main one is with your linker script doesn't have a .debug_info or .debug_line section.
