CodePudding user response：

Some of the libraries to link may not be built with the same toolchain. You can check with objdump.

Example (The "file format" may not be the exact result in your case):

$ aarch64-linux-gnu-objdump -TC libz.so

libz.so:     file format elf64-littleaarch64

Please confirm that the "file format" of all the libraries should match your toolchain.

CodePudding user response：

"file in wrong format" Err:

$ file main.o 
main.o: ELF 64-bit LSB relocatable, x86-64,

$file other *.o
sip_uri.o: ELF 64-bit LSB relocatable, ARM aarch64,

so main.o file format is x86-64 , but other .o files formate are ARM aarch64

but ....i still dont know how to solve that ( change the main.o file format)

the section of main.o in Makefile and i m sure the Problem at line:287
