1 | BFD is a 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-gnu-utils@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. |
