Playing with libfd and libopcodes

This directory contains examples that show howto call binutils bfd and opcodes libraries from C:

1. test_binary: this is the example from https://www.toothycat.net/wiki/wiki.pl?Binutils/libopcodes that was adapt to work with binutils 2.29.1
2. test_buffer_x86_64: this example shows howto disassemble a buffer containing x86 instructions
3. test_buffer_mep: similar to the second example with a more exotic architecture and binutils builtins

For convenience, the libbfd and libopcodes documentation from toothycat.net is archived in this repository.

Building examples

The examples assume that binutils 2.29.1 is built at the root of this repostitory. They can be compiled by typing make in the src/ directory.

Here is how binutils dynamic libraries can be installed:

curl https://ftp.gnu.org/gnu/binutils/binutils-2.29.1.tar.gz -O
tar xzvf binutils-2.29.1.tar.gz
cd binutils-2.29.1/
./configure --prefix=../built --enable-shared --enable-targets=all
make -j8

Note: by default binutils does not produce shared libraries. When enabling all targets, the resulting objdump binary is 61MB!
