1 BFD is an object file library. It permits applications to use the 2 same routines to process object files regardless of their format. 3 4 BFD is used by the GNU debugger, assembler, linker, and the binary 5 utilities. 6 7 The documentation on using BFD is scanty and may be occasionally 8 incorrect. Pointers to documentation problems, or an entirely 9 rewritten manual, would be appreciated. 10 11 There is some BFD internals documentation in doc/bfdint.texi which may 12 help programmers who want to modify BFD. 13 14 BFD is normally built as part of another package. See the build 15 instructions for that package, probably in a README file in the 16 appropriate directory. 17 18 BFD supports the following configure options: 19 20 --target=TARGET 21 The default target for which to build the library. TARGET is 22 a configuration target triplet, such as sparc-sun-solaris. 23 --enable-targets=TARGET,TARGET,TARGET... 24 Additional targets the library should support. To include 25 support for all known targets, use --enable-targets=all. 26 --enable-64-bit-bfd 27 Include support for 64 bit targets. This is automatically 28 turned on if you explicitly request a 64 bit target, but not 29 for --enable-targets=all. This requires a compiler with a 64 30 bit integer type, such as gcc. 31 --enable-shared 32 Build BFD as a shared library. 33 --with-mmap 34 Use mmap when accessing files. This is faster on some hosts, 35 but slower on others. It may not work on all hosts. 36 37 Report bugs with BFD to bug-binutils (a] gnu.org. 38 39 Patches are encouraged. When sending patches, always send the output 40 of diff -u or diff -c from the original file to the new file. Do not 41 send default diff output. Do not make the diff from the new file to 42 the original file. Remember that any patch must not break other 43 systems. Remember that BFD must support cross compilation from any 44 host to any target, so patches which use ``#ifdef HOST'' are not 45 acceptable. Please also read the ``Reporting Bugs'' section of the 46 gcc manual. 47 48 Bug reports without patches will be remembered, but they may never get 49 fixed until somebody volunteers to fix them. 50 52 Copyright (C) 2012-2014 Free Software Foundation, Inc. 53 54 Copying and distribution of this file, with or without modification, 55 are permitted in any medium without royalty provided the copyright 56 notice and this notice are preserved. 57
