MacOS ships with screen built-in, there is no need to install it separately. There is no need to add you user to the dialup group like on Linux. Serial port devices are available in /dev just like in Linux, however macOS sets the permissions of the device files such that read and write access are available for all groups and users. However, being aware of the tradeoff being made is something to be aware of before you choose to install Homebrew or MacPorts, depending on your security-related preferences. As a result the field importance of the security implications of Homebrew's choice about the ownership of all installed packages is not entirely clear. However tampering files installed by a package manager on macOS does not appear to be a popular attack vector for malware, thanks to the additional restrictions imposed on top of the standard Unix user permission system by the TCC subsystem in macOS ( read this article if you don't know what we are talking about). Other package managers such as MacPorts (or all Linux-based package managers for the various distributions) run as root (or as a specialized user with reduced privileges) in order to make it more difficult for malware to tamper any file in the package manager's prefix, and to prevent un-authorized users from modifying the set of packages installed. This is different than what all other package managers (on Linux and macOS) do.Īccording to Homebrew's developers, this approach purportedly has the advantage of reducing the attack surface of a hypothetic malware that modifies Homebrew's executables for malicious purposes, but it makes it possible for malware to modify all of the files installed by Homebrew easily (as executable distributed by Homebrew are often not signed). Homebrew specifically forbids being run with elevated privileges using sudo when installing packages. Homebrew, macOS, and filesystem permissions With Homebrew, installing st-flash and stm32flash can be performed through the following commands: If you prefer MacPorts, you can search the same packages (or 'ports') on the MacPorts port index. In the following discussion we will assume you have Homebrew available and installed on your system. Both of them provide all packages you need to get started with development on STM32 MCUs.

However, thanks to community efforts, there are two third-party package managers for macOS that provide a similar experience to Linux for easily installing tools and programs on the command line: Homebrew and MacPorts.

In contrast to Linux but similarly to Windows, macOS does not provide a system package manager. STM32 microcontrollers are the most important target for Miosix, and programming them requires specialized tools which on Linux are often installed through a package manager. Then, you can check with the command 'gcc -version'.Then follow the instructions on screen to complete the installation. When done, you can select your GCC 4.9 compiler using the command 'sudo port select -set gcc mp-gcc49'. Using sudo, execute the 'install' file in this release ('sudo. Xcode 2.5 (The last Xcode released for Tiger, although nothing will be compiled). Mac OS X 10.4.11 PowerPC (Should also work on Leopard, and be able to compile for Tiger from Leopard). At the end of the install, 'port sync' will also be run, updating your ports tree. This is because this installer will install them. The following MacPorts ports will be automatically uninstalled if they are found to be installed:Īpple-gcc42 cctools cloog gcc_select gettext gmp gpref isl isl18 ld64 ld64-97 libgcc7 libgcc6 libiconv libmacho-headers libmpc libunwind-headers mpfr ncurses xz zlib gcc49 Your system remains untouched, besides the addition of the new compiler and it's dependencies. After doing so, the ports tree is synced, binaries are installed, all changes are reverted, and finally the ports tree is synced with MacPorts proper. Essentially, the installer temporarily changes the MacPorts configuration files to use a local source for obtaining the ports tree and binary archives. This installer on the other hand takes just under 2 hours on my Mac to install everything. All together, compiling this can easily take a day or 2. GNU GCC 4.9 requires many dependencies and bootstrap compilers when compiling completely from source using MacPorts for PowerPC Mac OS X 10.4 Tiger. =MacPorts GCC 4.9 Binary Installer For PowerPC Mac OS X Tiger
