Compiling from sources

Microsoft Windows (10, 11)

Common Requirements

On Windows users should ensure that the following software is installed:

• git (optional, but recommended)
• cmake
• 7-zip
• MinGW-w64

Installation

1. Install git from https://git-scm.com/download/win

2. Install cmake from https://cmake.org/download
   Ensure that you add cmake to the $PATH system variable when following the instructions by the setup assistant.

3. Install MinGW-w64
   Download MinGW-w64 from https://github.com/niXman/mingw-builds-binaries/releases/download/13.2.0-rt_v11-rev1/x86_64-13.2.0-release-win32-seh-msvcrt-rt_v11-rev1.7z. Extract content to C:\mingw-w64\ and add C:\mingw-w64\bin\ to PATH-Variable.
   

4. Create a new destination folder at a place of your choice

5. Open the command-line (cmd.exe) and execute cd C:\$Path-to-your-destination-folder$\

6. Fetch the project sourcefiles by running git clone https://github.com/stlink-org/stlink.gitfrom the command-line (cmd.exe)
   or download and extract the stlink zip-sourcefolder from the Release page on GitHub.

Building

MinGW-w64

1. Open command-line with administrator privileges
2. Move to the stlink directory
3. Execute mingw64-build.bat

NOTE:
Per default the build script (currently) uses C:\mingw-w64\x86_64-8.1.0-release-win32-sjlj-rt_v6-rev0\mingw64\bin.
When installing different toolchains make sure to update the path in the mingw64-build.bat.
This can be achieved by opening the .bat file with a common text editor.

Options:

• /m - compilation runs in parallel utilizing multiple cores
• /p:Configuration=Release - generates Release, optimized build.

Directory <project_root>\build\Release contains final executables. (st-util.exe is located in <project_root>\build\src\gdbserver\Release).

NOTE 1:

Executables link against libusb.dll library. It has to be placed in the same directory as binaries or in PATH. It can be copied from: <project_root>\build\3rdparty\libusb-{version}\MS{arch}\dll\libusb-1.0.dll.

NOTE 2:

ST-LINK drivers are required for stlink to work.

Linux

Common requirements

Install the following packages from your package repository:

• git
• gcc or clang or mingw32-gcc or mingw64-gcc (C-compiler; very likely gcc is already present)
• build-essential (on Debian based distros (Debian, Ubuntu))
• cmake
• rpm (on Debian based distros (Debian, Ubuntu), needed for package build with make package)
• libusb-1.0
• libusb-1.0-0-dev (development headers for building)
• libgtk-3-dev (optional, needed for stlink-gui)
• pandoc (optional, needed for generating manpages from markdown)

or execute (Debian-based systems only): apt-get install gcc build-essential cmake libusb-1.0 libusb-1.0-0-dev libgtk-3-dev pandoc

(Replace gcc with the intended C-compiler if necessary or leave out any optional package not needed.)

Installation

1. Open a new terminal console
2. Create a new destination folder at a place of your choice e.g. at ~/git: mkdir $HOME/git
3. Change to this directory: cd ~/git
4. Fetch the project sourcefiles by running git clone https://github.com/stlink-org/stlink.git

Building

Installation:

1. Change into the project source directory: cd stlink
2. Run make clean -- required by some linux variants.
3. Run make release to create the Release target.
4. Run make install to full install the package with complete system integration. This might require sudo permissions.
5. Run make debug to create the Debug target (optional)
   The debug target is only necessary in order to modify the sources and to run under a debugger.
6. Run make packageto build a Debian Package. The generated packages can be found in the subdirectory ./build/Release/dist.

As an option you may also install to an individual user-defined folder e.g $HOME with make install DESTDIR=$HOME.

How to avoid the error message: "Can not open shared object file"

When installing system-wide (sudo make install) the dynamic library cache needs to be updated with the command ldconfig.

Removal:

1. Run make uninstall to perform a clean uninstall of the package from the system.
2. Run make clean to clean the build-folder within the project source and remove all compiled and linked files and libraries.

Cross-Building for Windows

Install the following packages from your package repository:

• mingw-w64
• mingw-w64-common
• mingw-w64-i686-dev
• mingw-w64-x86-64-dev

After following the steps for installation above, proceed with from the build dircetory itself:

$ sudo sh ./cmake/packaging/windows/generate_binaries.sh

The generated zip-packages can be found in the subdirectory ./build/dist.

Set device access permissions and the role of udev

By default most distributions don't allow access to USB devices. In this context udev rules, which create devices nodes, are necessary to run the tools without root permissions. To achieve this you need to ensure that the group plugdev exists and the user who is trying to access these devices is a member of this group.

Within the sourcefolder of the project, these rules are located in the subdirectory config/udev/rules.d and are automatically installed along with sudo make install on linux. Afterwards it may be necessary to reload the udev rules:

$ sudo cp -a config/udev/rules.d/* /lib/udev/rules.d/
$ sudo udevadm control --reload-rules
$ sudo udevadm trigger

udev will now create device node files, e.g. /dev/stlinkv3_XX, /dev/stlinkv2_XX, /dev/stlinkv1_XX.

Special note on the use of STLink/V1 programmers (legacy):

As the STLINKV1's SCSI emulation is somehow broken, the best advice possibly is to tell your operating system to completely ignore it.
Choose one of the following options before connecting the device to your computer:

• modprobe -r usb-storage && modprobe usb-storage quirks=483:3744:i
• OR
  1. echo "options usb-storage quirks=483:3744:i" >> /etc/modprobe.conf
  2. modprobe -r usb-storage && modprobe usb-storage
• OR
  1. cp stlink_v1.modprobe.conf /etc/modprobe.d
  2. modprobe -r usb-storage && modprobe usb-storage

Build options

Build using a different directory for shared libs

To put the compiled shared libs into a different directory during installation, you can use the cmake option cmake -DLIB_INSTALL_DIR:PATH="/usr/lib64" ...

Standard installation directories

The cmake build system of this toolset includes GNUInstallDirs to define GNU standard installation directories. This module provides install directory variables as defined by the GNU Coding Standards.

Below are the preset default cmake options, which apply if none of these options are redefined:

• -DCMAKE_INSTALL_SYSCONFDIR=/etc
• -DCMAKE_INSTALL_PREFIX=/usr/local

Please refer to the related cmake documentation for details.
