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. BSD

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

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. SEE ALSO
