[Elftoolchain-developers] Build libelf as a shared library on OpenBSD

[Sunil N. <su...@su...>]

Hello,

OpenBSD's bsd.lib.mk requires both SHLIB_MAJOR and SHLIB_MINOR to be
defined for building shared library. NOPIC on OpenBSD suppress PIC
versions as well as shared libraries.

Earlier....
make -n | fgrep shared

with this diff...
make -n | fgrep shared
cc -shared -fpic  -o libelf.so.1.0  `lorder elf.so elf_begin.so
elf_cntl.so elf_end.so elf_errmsg.so elf_errno.so elf_data.so
elf_fill.so elf_flag.so elf_getarhdr.so elf_getarsym.so elf_getbase.so

Nevermind, shared library on OpenBSD might be broken. I get a

 elf_begin: Request error: invalid ELF_C_* argument

which doesn't happen with static library.

Hi,

I think "invalid ELF_C_* argument" is GNU libelf error message.

oops, that's correct, I linked with the GNU library. libelf.so works fine now
on OpenBSD.
