- Make sure you’re ready to upgrade. Before you upgrade, we recommend that you back up your Mac. Then, if your Mac is running OS X Mavericks 10.9 or later, you can upgrade directly to macOS Catalina.
- Hi, i'm italian and i need your help. For to disassemble binary code on ubuntu, you use the command objdump, already implemented on it. But if i want disassemble with mac binary code? I tried to install just the famous objdump but I can not. Surfing the internet, I read that is contained.
GNU Binutils
The GNU Binutils are a collection of binary tools. The main ones are:
Objdump (disassemble) on Mac OS X There are two possible ways to disassemble a binary in Mac OS X: (1) install GNU binutils; (2) use otool. (1) Install GNU binutils from the source (download), or from the MacPort. Make sure you’re ready to upgrade. Before you upgrade, we recommend that you back up your Mac. Then, if your Mac is running OS X Mavericks 10.9 or later, you can upgrade directly to macOS Catalina.
- ld - the GNU linker.
- as - the GNU assembler.
But they also include:
- addr2line - Converts addresses into filenames and line numbers.
- ar - A utility for creating, modifying and extracting from archives.
- c++filt - Filter to demangle encoded C++ symbols.
- dlltool - Creates files for building and using DLLs.
- gold - A new, faster, ELF only linker, still in beta test.
- gprof - Displays profiling information.
- nlmconv - Converts object code into an NLM.
- nm - Lists symbols from object files.
- objcopy - Copies and translates object files.
- objdump - Displays information from object files.
- ranlib - Generates an index to the contents of an archive.
- readelf - Displays information from any ELF format object file.
- size - Lists the section sizes of an object or archive file.
- strings - Lists printable strings from files.
- strip - Discards symbols.
- windmc - A Windows compatible message compiler.
- windres - A compiler for Windows resource files.
Most of these programs use BFD, the Binary File Descriptor library, to do low-level manipulation. Many of them also use the opcodes library to assemble and disassemble machine instructions.
The binutils have been ported to most major Unix variants as well as Wintel systems, and their main reason for existence is to give the GNU system (and GNU/Linux) the facility to compile and link programs.
Obtaining binutils
The latest release of GNU binutils is 2.35.1. The various NEWS files (binutils, gas, and ld) have details of what has changed in this release.
See the SOFTWARE page for information on obtaining releases of GNU binutils and other GNU software. The current release can be downloaded from https://ftp.gnu.org/gnu/binutils or, preferably, from a nearby mirror through the generic URL https://ftpmirror.gnu.org/binutils.
Objdump For Mac Os Versions
If you plan to do active work on GNU binutils, you can access the development source tree by anonymous git:
git clone git://sourceware.org/git/binutils-gdb.git
Alternatively, you can use the gitweb interface, or the source snapshots, available as bzipped tar files via anonymous FTP from ftp://sourceware.org/pub/binutils/snapshots.
Bug reports
There is a bug-tracking system at https://sourceware.org/bugzilla/.
Mailing lists
There are three binutils mailing lists:
- <[email protected]> (archives)
- For reporting bugs.
- <[email protected]> (archives)
- For discussing binutils issues.
- binutils-cvs (archives)
- A read-only mailing list containing the notes from checkins to the binutils git repository. (This list has an odd name for historical reasons.)
You can use this form to subscribe to the
[email protected]

mailing lists:To subscribe to the
[email protected]
mailing list, see the bug-binutils info page.You may wish to browse the old mail archives of the gas2 and bfd mailing lists. These were the discussion lists for binutils until May 1999. Please do not send mail to them any longer.
Documentation
The documentation for binutils 2.35.1 is available.
A guide to porting the binutils to a new target has been contributed.
Windows¶
PyInstaller runs in Windows 8 or newer(Windows 7 should work too, but is not supported).It can create graphical windowed apps (apps that do not need a command window).
PyInstaller requires two Python modules in a Windows system.It requires either the PyWin32 or pypiwin32 Python extension for Windows.If you install PyInstaller using pip, and PyWin32 is not already installed,pypiwin32 is automatically installed.PyInstaller also requires the pefile package.
The pip-Win package is recommended, but not required.
Mac OS X¶
PyInstaller runs in Mac OS X 10.7 (Lion) or newer.It can build graphical windowed apps (apps that do not use a terminal window).PyInstaller builds apps that are compatible with the Mac OS X release inwhich you run it, and following releases.It can build 32-bit binaries in Mac OS X releases that support them.
GNU/Linux¶
PyInstaller requires the
ldd
terminal application to discoverthe shared libraries required by each program or shared library.It is typically found in the distribution-package glibc
or libc-bin
.It also requires the
objdump
terminal application to extractinformation from object filesand the objcopy
terminal application to append data to thebootloader.These are typically found in the distribution-package binutils
.AIX, Solaris, FreeBSD and OpenBSD¶
Objdump For Mac Os High Sierra
Users have reported success running PyInstaller on these platforms,but it is not tested on them.The
ldd
and objdump
commands are needed.Each bundled app contains a copy of a bootloader,a program that sets up the application and starts it(see The Bootstrap Process in Detail).
When you install PyInstaller using pip, the setup will attemptto build a bootloader for this platform.If that succeeds, the installation continues and PyInstaller is ready to use.
If the pip setup fails to build a bootloader,or if you do not use pip to install,you must compile a bootloader manually.The process is described under Building the Bootloader.
