ELF2AOUT(1)						    BSD General Commands Manual 					       ELF2AOUT(1)

NAME

     elf2aout -- convert a NetBSD ELF-format executable to NetBSD a.out format

SYNOPSIS

     elf2aout elf-file aout-file

DESCRIPTION

     Reads a fully-linked ELF executable (such as a  linked kernel) and produces an equivalent a.out format executable file.

     The elf2aout utility is used to convert native NetBSD ELF binaries to a.out format, for compatibility with bootblocks and kernel-reading
     utilities like kvm(3) and kvm_mkdb(8), which currently expect an a.out format kernel.

SEE ALSO

     elf2ecoff(1), ld(1), kvm(3), a.out(5), elf(5), kvm_mkdb(8)

HISTORY

     elf2aout was originally developed for NetBSD/pmax by Ted Lemon and was first distributed with the pmax port of NetBSD 1.1.

BUGS

     elf2aout assumes there are no multiply-referenced symbols in the input ELF symbol section.  It may be necessary to link with -x to avoid such
     duplicate symbols.

     In some environments, the GNU binutils objcopy(1) utility may be a better solution than elf2aout.

GELF_CHECKSUM(3)					   BSD Library Functions Manual 					  GELF_CHECKSUM(3)

NAME

     elf32_checksum, elf64_checksum, gelf_checksum -- return the checksum of an ELF object

LIBRARY

     ELF Access Library (libelf, -lelf)

SYNOPSIS

     #include <libelf.h>

     long
     elf32_checksum(Elf *elf);

     long
     elf64_checksum(Elf *elf);

     #include <gelf.h>

     long
     gelf_checksum(Elf *elf);

DESCRIPTION

     These functions return a simple checksum of the ELF object described by their argument elf.  The checksum is computed in way that allows its
     value to remain unchanged in presence of modifications to the ELF object by utilities like strip(1).

     Function elf32_checksum() returns a checksum for an ELF descriptor elf of class ELFCLASS32.

     Function elf64_checksum() returns a checksum for an ELF descriptor elf of class ELFCLASS64.

     Function gelf_checksum() provides a class-independent way retrieving the checksum for ELF object elf.

RETURN VALUES

     These functions return the checksum of the ELF object, or zero in case an error was encountered.

ERRORS

     These functions may fail with the following errors:

     [ELF_E_ARGUMENT]  Argument elf was NULL.

     [ELF_E_ARGUMENT]  Argument elf was not a descriptor for an ELF file.

     [ELF_E_ARGUMENT]  The ELF descriptor elf was not opened for reading or updating.

     [ELF_E_CLASS]     For functions elf32_checksum() and elf64_checksum(), ELF descriptor elf did not match the class of the called function.

     [ELF_E_HEADER]    The ELF object specified by argument elf had a malformed executable header.

     [ELF_E_RESOURCE]  An out of memory condition was detected during processing.

     [ELF_E_SECTION]   The ELF object specified by argument elf contained a section with a malformed section header.

     [ELF_E_VERSION]   The ELF object was of an unsupported version.
