Changed since recent changes, but still fails (same on i386, but this is an issue on amd64 too): > strip -d 6.out BFD: 6.out: warning: Empty loadable segment detected, is this intentional ? BFD: stE2SbKS: warning: allocated section `.interp' not in segment > ./6.out ELF interpreter ^?ELF^B^A^A not found Abort Does this happen on Linux? |
This is a known issue. If you strip the binary you throw away the runtime symbol information that gets used for stack traces and some aspects of reflection. Don't do that. ;-) We plan to move that data into a rodata segment and then strip will not break the binary but will also not remove very much. Status changed to LongTerm. |
Where do the runtime symbols get stored? Everywhere that I'm seeing right now implies that they're either in .hash or .gosymtab which would suggest that if those sections are read-only, they shouldn't get tossed by strip. But they are: > objdump -hrt ../gofmt/gofmt ../gofmt/gofmt: file format elf64-x86-64 Sections: Idx Name Size VMA LMA File off Algn 0 .interp 00000015 00000000004007eb 00000000004007eb 000007eb 2**0 CONTENTS, ALLOC, LOAD, READONLY, DATA 1 .got 00000000 0000000000446678 0000000000446678 00046678 2**3 CONTENTS, ALLOC, LOAD, DATA 2 .got.plt 00000000 0000000000446d48 0000000000446d48 00046d48 2**3 CONTENTS, ALLOC, LOAD, DATA 3 .dynsym 00000018 0000000000464a28 0000000000464a28 00064a28 2**3 CONTENTS, ALLOC, LOAD, READONLY, DATA 4 .dynstr 00000004 0000000000446470 0000000000446470 00046470 2**0 CONTENTS, ALLOC, LOAD, READONLY, DATA 5 .hash 00000010 0000000000492ae0 0000000000492ae0 00092ae0 2**3 CONTENTS, ALLOC, LOAD, READONLY, DATA 6 .rela 00000000 00000000004472d8 00000000004472d8 000472d8 2**3 CONTENTS, ALLOC, LOAD, READONLY, DATA 7 .dynamic 00000090 0000000000482e48 0000000000482e48 00082e48 2**3 CONTENTS, ALLOC, LOAD, DATA 8 .text 00044f26 0000000000400800 0000000000400800 00000800 2**3 CONTENTS, ALLOC, LOAD, READONLY, CODE 9 .data 00060748 0000000000446000 0000000000446000 00046000 2**3 CONTENTS, ALLOC, LOAD, DATA 10 .bss 002145d0 00000000004a6748 00000000004a6748 000a6748 2**3 ALLOC 11 .gosymtab 0007664f 0000000000000000 0000000000000000 000a7008 2**0 CONTENTS, READONLY 12 .gopclntab 000057e6 0000000000000000 0000000000000000 0011d657 2**0 CONTENTS, READONLY SYMBOL TABLE: no symbols |
