| 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@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.
