Why can not run debug binary (*.debug) on linux using cross compile?

After cross Compiled Linux DS binaries on Win10( v13_clang-7.0.1-centos7), I got four files:

  1. Test1Server
  2. Test1Server.debug
  3. Test1Server.sym
  4. Test1Server.target

the Test1Server is running ok, but Test1Server.debug launch failed, is not Test1Server.debug a debug version?how can I get sym info when using systemtap to analyse DS process? thanks, expect your help!

$ ./Test1Server.debug
-bash: ./Test1Server.debug: cannot execute binary file

$ objdump -x Test1Server.debug

Test1Server.debug:     file format elf64-x86-64

this question is wrong, the XXXServer.debug file is debug symbol file, the .text is different from XXXServer. Another question, what is using of XXXServer.sym? Why need it when we have XXXServer.debug file.

3

.sym can be used to symbolicate the crash callstack even without the presence of .debug (which is debugger-level info).
