README - elf2flt ---------------- Copyright (C) 2001-2003, SnapGear (www.snapgear.com) davidm@snapgear.com gerg@snapgear.com This is Free Software, under the GNU Public Licence v2 or greater. See LICENSE.TXT for more details. Elf2flt with PIC, ZFLAT and full reloc support. Currently supported targets include: m68k/ColdFire, ARM, Sparc, NEC v850, MicroBlaze, h8300, SuperH, and Blackfin. COMPILING: You need an appropriate libbfd.a and libiberty.a for your target to build this tool. They are normally part of the binutils package. To compile elf2flt do: ./configure --target= --with-libbfd= --with-libiberty= make make install The argument to configure specifies what the target architecture is. This should be the same target as you used to build the binutils and gcc cross development tools. The --with-libbfd and --with-libiberty arguments specify where the libbfd.a and libiberty.a library files are to use. FILES: README - this file configure - autoconf configuration shell script configure.in- original autoconf file config.* - autoconf support scripts Makefile.in - Makefile template used by configure elf2flt.c - the source flthdr.c - flat header manipulation program flat.h - header from uClinux kernel sources elf2flt.ld - an example linker script that works for C/C++ and uClinux ld-elf2flt - A linker replacement that implements a -elf2flt option for the linker and runs elf2flt automatically for you. It auto detects PIC/non-PIC code and adjusts its option accordingly. It uses the environment variable FLTFLAGS when running elf2flt. It runs /.../m68k-elf-ld.real to do the actual linking. TIPS: The ld-elf2flt produces 2 files as output. The binary flat file X, and X.gdb which is used for debugging and PIC purposes. The '-p' option requires an elf executable linked at address 0. The elf2flt.ld provided will generate the correct format binary when linked with the real linker with *no* '-r' option for the linker. The '-r' flag can be added to PIC builds to get contiguous code/data. This is good for loading application symbols into gdb (add-symbol-file XXX.gdb).
