Why I am getting this output when run readelf -s
elf, linux-kernel, objcopy
Solution
It is simply that the string is too long and `readelf` is truncating. Try `objdump -x main.o`.
Problem
I have Linux Kernel with me and trying to generate ELF Header on it using objcopy tool, Below is the first step ``` objcopy -I binary -B i386 -O elf32-i386 --rename-section .data=.text linux_kernel.bin main.o ``` And after this I wanted to read symbol table using readelf -s main.o ,but getting strange symbols, below is output ``` Symbol table '.symtab' contains 5 entries: Num: Value Size Type Bind Vis Ndx Name 0: 00000000 0 NOTYPE LOCAL DEFAULT UND 1: 00000000 0 SECTION LOCAL DEFAULT 1 2: 00000000 0 NOTYPE GLOBAL DEFAULT 1 _binary_linux_kernel_bin_ 3: 004df650 0 NOTYPE GLOBAL DEFAULT 1 _binary_linux_kernel_bin_ 4: 004df650 0 NOTYPE GLOBAL DEFAULT ABS _binary_linux_kernel_bin_ ``` Now should be able to see symbols like ``` _binary_linux_kernel_bin_start _binary_linux_kernel_bin__end _binary_linux_kernel_bin_size ``` Can any body let me know where I am doing wrong?? or is it expected one?? Why I wanted to see proper symbol because have to do something like below one ``` --entry_point=_binary_linux_kernel_bin_start ```
