Unfortunately, Eclipse is not capable of communicating with any debugger other than GDB (yet). Here is a step-by-step guide for installing and configuring GDB. As with GCC, the easiest way to install GDB is through Homebrew. In a Terminal window, run the command brew install gdb, and wait for it to complete. (As usual, it may. Homebrew’s package index.

The easiest way to install a number of Unix style applications and open source software onto macOS Big Sur, Catalina, Mojave and earlier Sierra OS versions is via a package manager, unfortunately, macOS Big Sur doesn’t come with one, but fortunately, some good folks care, they come in the form of Homebrew.

The install of Homebrew also works on macOS Catalina, macOS Mojave, (High)Sierra, El Capitan, and Yosemite, so macOS 10.10 – 10.14

Homebrew isn’t the only option, also available is MacPorts and Fink but Homebrew is the newest and most popular of the trio.

Install Homebrew

To download install Homebrew run the install script on the command line as below and let the script do its thing:

If you don’t have Apples Xcode Command Line Tools installed it will alert you to that it will install it and carry on with the Homebrew installation and download the Command Line Tools you will need to enter your admin password at some point.

Then Homebrew is installed.
After this Homebrew is installed and ready to install other apps.

To get started run brew help can give some command example usage.

To check for any issues with the Homebrew install run:

One issue that typically comes up is an outdated or missing version of Xcode.

For the latest macOS, brew doctor will warn that the Homebrew install won’t be 100% if Xcode is not up to date, so update Xcode from the App Store.

To search for an application:

To install

To list all apps installed by Homebrew

To remove an installed application

To update Homebrew itself

To see what packages are out of date but not to upgrade them

To see what upgrade packages all or singular

To hold a package at a certain version

To release a package from a certain version

To see what else you can do

Where does Homebrew install stuff …. in the Cellar

Where the brew lives.

You can see your Homebrew configuration by running

The output should be similar to …

All installations via Homebrew are filed independently in the filing system in /usr/local/Cellar and linked into /usr/local/bin which is a directory which allows you to run these commands and apps as if part of the regular operating system.

This directory is also out of the SIP bounds so there should be no authentication macOS error dialog boxes.

Remove Home-brew and all packages

To remove the Home-brew installation and all packages it has installed..

HomeBrew is a great package manager just start installing some apps and explore.!

Additionally, SUMO provides native macOS application bundles for its graphical applications, so they can be added to the macOS dock. There is a separate brew cask that will copy these bundles to the Applications folder: brew cask install sumo-gui. 苹果公司在今天（2019.10.08）凌晨正式推送了 macOS Catalina（10.15)更新，新系统将诞生了18年的 iTune. You will need a macOS computer running High Sierra or higher with administrative access and an internet connection. Step 1 — Using the macOS Terminal. To access the command line interface on your Mac, you’ll use the Terminal application provided by macOS.

You can install cryptography with pip:

Hi, I am running MacOS X 10.14.3 (German Version) which I installed directly from the downloaded install ISO in the latest VMware Fusion. Now I get a notification form softwareupdate that there is an update available. Updated to reflect the release of macOS 10.5 Catalina Updated to add back PHP 5.6 and PHP 7.0 from and external deprecated keg Updated to reflect the latest release of PHP 7.3 and the removal of PHP 7.0 from Brew.

If this does not work please upgrade your pip first, as that is thesingle most common cause of installation problems.

Supported platforms¶

Currently we test cryptography on Python 3.6+ and PyPy3 7.3.1 on theseoperating systems.

x86-64 & AArch64 CentOS 8.x
x86-64 Fedora (latest)
x86-64 macOS 10.15 Catalina
x86-64 & AArch64 Ubuntu 18.04, 20.04
x86-64 Ubuntu rolling
x86-64 Debian Stretch (9.x), Buster (10.x), Bullseye (11.x), and Sid(unstable)
x86-64 Alpine (latest)
32-bit and 64-bit Python on 64-bit Windows Server 2019

We test compiling with clang as well as gcc and use the followingOpenSSL releases:

OpenSSL1.1.0-latest
OpenSSL1.1.1-latest

Building cryptography on Windows¶

The wheel package on Windows is a statically linked build (as of 0.5) so alldependencies are included. To install cryptography, you will typicallyjust run

If you prefer to compile it yourself you’ll need to have OpenSSL installed.You can compile OpenSSL yourself as well or use a binary distribution.Be sure to download the proper version for your architecture and Python(VC2015 is required for 3.6 and above). Wherever you place your copy of OpenSSLyou’ll need to set the LIB and INCLUDE environment variables to includethe proper locations. For example:

As of OpenSSL 1.1.0 the library names have changed from libeay32 andssleay32 to libcrypto and libssl (matching their names on all otherplatforms). cryptography links against the new 1.1.0 names by default. Ifyou need to compile cryptography against an older version then you mustset CRYPTOGRAPHY_WINDOWS_LINK_LEGACY_OPENSSL or else installation will fail.

You will also need to have Rust installed andavailable.

If you need to rebuild cryptography for any reason be sure to clear thelocal wheel cache.

Building cryptography on Linux¶

Note

If you are on RHEL/CentOS/Fedora/Debian/Ubuntu or another distributionderived from the preceding list, then you should upgrade pip andattempt to install cryptography again before following the instructionsto compile it below. These platforms will receive a binary wheel andrequire no compiler if you have an updated pip!

cryptography ships manylinux wheels (as of 2.0) so all dependenciesare included. For users on pip 19.0 or above running on a manylinux2010(or greater) compatible distribution (almost everything except Alpine) allyou should need to do is:

If you are on Alpine or just want to compile it yourself thencryptography requires a C compiler, a Rust compiler, headers for Python (ifyou’re not using pypy), and headers for the OpenSSL and libffi librariesavailable on your system.

On all Linux distributions you will need to have Rust installed andavailable.

Alpine¶

Warning

The Rust available by default in Alpine < 3.12 is older than the minimumsupported version. See the Rust installation instructions for information about installing a newer Rust.

If you get an error with openssl-dev you may have to use libressl-dev.

Debian/Ubuntu¶

Warning

The Rust available in current Debian stable and some Ubuntu versions isolder than the minimum supported version. Ubuntu 18.04 and 20.04 aresufficiently new, but otherwise please see theRust installation instructions for informationabout installing a newer Rust.

Fedora/RHEL 8/CentOS 8¶

Warning

For RHEL and CentOS you must be on version 8.3 or newer for the commandbelow to install a sufficiently new Rust. If your Rust is less than 1.41.0please see the Rust installation instructionsfor information about installing a newer Rust.

RHEL 7/CentOS 7¶

Warning

How To Install Brew On Catalina

You must install Rust using the Rust installation instructions. cryptography requires a Rust version newer thanwhat is provided in the distribution packages.

Building¶

You should now be able to build and install cryptography. To avoid gettingthe pre-built wheel on manylinux compatible distributions you’ll need touse --no-binary.

Using your own OpenSSL on Linux¶

Python links to OpenSSL for its own purposes and this can sometimes causeproblems when you wish to use a different version of OpenSSL with cryptography.If you want to use cryptography with your own build of OpenSSL you will need tomake sure that the build is configured correctly so that your version ofOpenSSL doesn’t conflict with Python’s.

The options you need to add allow the linker to identify every symbol correctlyeven when multiple versions of the library are linked into the same program. Ifyou are using your distribution’s source packages these will probably bepatched in for you already, otherwise you’ll need to use options something likethis when configuring OpenSSL:

Static Wheels¶

Cryptography ships statically-linked wheels for macOS, Windows, and Linux (viamanylinux). This allows compatible environments to use the most recentOpenSSL, regardless of what is shipped by default on those platforms. SomeLinux distributions (most notably Alpine) are not manylinux compatible sowe cannot distribute wheels for them.

However, you can build your own statically-linked wheels that will work on yourown systems. This will allow you to continue to use relatively old Linuxdistributions (such as LTS releases), while making sure you have the mostrecent OpenSSL available to your Python programs.

To do so, you should find yourself a machine that is as similar as possible toyour target environment (e.g. your production environment): for example, spinup a new cloud server running your target Linux distribution. On this machine,install the Cryptography dependencies as mentioned in Building cryptography on Linux.Please also make sure you have virtualenv installed: this should beavailable from your system package manager.

Then, paste the following into a shell script. You’ll need to populate theOPENSSL_VERSION variable. To do that, visit openssl.org and find thelatest non-FIPS release version number, then set the string appropriately. Forexample, for OpenSSL 1.0.2k, use OPENSSL_VERSION='1.0.2k'.

When this shell script is complete, you’ll find a collection of wheel files ina directory called wheelhouse. These wheels can be installed by asufficiently-recent version of pip. The Cryptography wheel in thisdirectory contains a statically-linked OpenSSL binding, which ensures that youhave access to the most-recent OpenSSL releases without corrupting your systemdependencies.

Building cryptography on macOS¶

Note

If installation gives a fatalerror:'openssl/aes.h'filenotfoundsee the FAQ for information about how to fix this issue.

The wheel package on macOS is a statically linked build (as of 1.0.1) so forusers with pip 8 or above you only need one step:

If you want to build cryptography yourself or are on an older macOS version,cryptography requires the presence of a C compiler, development headers, andthe proper libraries. On macOS much of this is provided by Apple’s Xcodedevelopment tools. To install the Xcode command line tools (on macOS 10.10+)open a terminal window and run:

Macos Catalina Brew Install

This will install a compiler (clang) along with (most of) the requireddevelopment headers.

You will also need to have Rust installed andavailable, which can be obtained from Homebrew,MacPorts, or directly from the Rust website.

Brew Install Openssl Mac Catalina

Finally you need OpenSSL, which you can obtain from Homebrew or MacPorts.Cryptography does not support the OpenSSL/LibreSSL libraries Apple shipsin its base operating system.

To build cryptography and dynamically link it:

MacPorts:

You can also build cryptography statically:

MacPorts:

If you need to rebuild cryptography for any reason be sure to clear thelocal wheel cache.

Rust¶

Note

If you are on RHEL/CentOS/Fedora/Debian/Ubuntu or another distributionderived from the preceding list, then you should upgrade pip (ina virtual environment!) and attempt to install cryptography againbefore trying to install the Rust toolchain. These platforms will receivea binary wheel and require no compiler if you have an updated pip!

Building cryptography requires having a working Rust toolchain. The currentminimum supported Rust version is 1.41.0. This is newer than the Rust mostpackage managers ship, so users will likely need to install with theinstructions below.

Instructions for installing Rust can be found on the Rust Project’s website.We recommend installing Rust with rustup (as documented by the RustProject) in order to ensure you have a recent version.

Rust is only required when building cryptography, meaning that you mayinstall it for the duration of your pipinstall command and then remove itfrom a system. A Rust toolchain is not required to usecryptography. Indeployments such as docker, you may use a multi-stage Dockerfile whereyou install Rust during the build phase but do not install it in the runtimeimage. This is the same as the C compiler toolchain which is also required tobuild cryptography, but not afterwards.

1Notes

Some system emulations on Linux use KVM, a special emulation mode which claims to reach nearly native speed.KVM is mainly used for x86 (32 and 64 bit) emulation on x86 hosts running Linux. Should you want to run Qemu with KVM support on a G5, depending on your distribution, you might have to compile your own kernel with KVM support.

If your host's (your computer) architecture matches the guest's (QEMU) architecture and is running Mac OS 10.10 or higher, then you could speed up execution to near native speed using this option: -accel hvf

Installing QEMU using a package manager

Building QEMU for macOS

The system requirements are:

One of the two most recent versions of macOS (currently Catalina or Big Sur)
The clang compiler shipped with the version of Xcode for that OS X. GCC might also work, but we recommend clang

Additional build requirements are:

make (when installed through brew, make is installed as gmake, so use gmake)

After downloading the QEMU source code, double-click it to expand it.

Then configure and make QEMU. The target-list option is used to build only the machine or machines you want. If you don't specify it, all machines would be built. Probably not what you want.

This way doesn't require you to wait for the configure command to complete:

If your system has the 'say' command, you can use it to tell you when QEMU is done

You can use './configure --help' to see a full list of options.

Here are all the currently available machines:

aarch64-softmmu
alpha-softmmu
arm-softmmu
cris-softmmu
i386-softmmu
lm32-softmmu
m68k-softmmu
microblaze-softmmu
microblazeel-softmmu
mips-softmmu
mips64-softmmu
mips64el-softmmu
mipsel-softmmu
moxie-softmmu
or32-softmmu
ppc-softmmu
ppc64-softmmu
ppcemb-softmmu
s390x-softmmu
sh4-softmmu
sh4eb-softmmu
sparc-softmmu
sparc64-softmmu
tricore-softmmu
unicore32-softmmu
x86_64-softmmu
xtensa-softmmu
xtensaeb-softmmu

We recommend building QEMU with the -default compiler provided by Apple, for your version of Mac OS X (which will be 'clang'). The configure script will automatically pick this.

Errors on old compilers

Note: If after the configure step you see a message like this:

you may have to install your own version of gcc. You can build it from source (expect that to take several hours) or obtain third party binaries of gcc available from Homebrew or MacPorts.

You can have several versions of GCC on your system. To specify a certain version, use the --cc and --cxx options.
