Code: $ LD_LIBRARY_PATH=. ./1 ./1: error while loading shared libraries: libhello.so: failed to map segment from shared object You seem to have a problem with your program headers: Code: Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flags Align NULL 0x0000000000000000 0x0000000000000000 0x0000000000000000 0x0000000000000000 0x0000000000000000 0 LOAD 0x0000000000000000 0x0000000000001000 0x0000000000001000 0x0000000000000000 0x0000000000000000 RW 1000 LOAD 0x0000000000001000 0x0000000000001000 0x0000000000001000 0x0000000000000000 0x0000000000000000 RW 1000 LOAD 0x0000000000001000 0x0000000000000000 0x0000000000000000 0x0000000000000016 0x0000000000000016 R E 1000 LOAD 0x0000000000002000 0x0000000000001000 0x0000000000001000 0x00000000000001f1 0x00000000000001f1 RWE 1000 DYNAMIC 0x00000000000020f8 0x00000000000010f8 0x00000000000010f8 0x00000000000000d0 0x00000000000000d0 RWE 1000 I see three issues here: (1) the first two LOAD segments are both zero size; (2) the other two LOAD segments overlap the first two; (3) the DYNAMIC segment is misaligned -- the alignment is set to 1000 but its address is not page-aligned. |
