我有一個非常簡單的程序(simple.c):鏈接器腳本不工作?
#include <stdio.h>
int main(){
int a = 4;
return 0;
}
我嘗試使用下面的鏈接腳本(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
}
我使用下面的命令來編譯和鏈接:
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
我收到以下錯誤:
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

simple.o: In function `main':
simple.c:(.text+0xa): undefined reference to `puts'
如果我嘗試使用:
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
它給出了錯誤
ld: cannot find -lc
有什麼建議?我想要做的就是將我的simple.c放入不同的內存區域,然後默認。
