![]() The prerequisite tools include Python, Git, cross-compilers, menuconfig tool, CMake and Ninja. Once that it done, the build steps generate and install the correct 2.7 library, and the import test works fine. There is no JTAG over USB support on the BeagleBone Black. The second forces the selection of the right include path and library. The first might not be required (ir just cleans up any old cache info), but better safe than sorry. DPYTHON_INCLUDE_DIR:PATH=/usr/include/python2.7 -DPYTHON_LIBRARY:FILEPATH=/usr/lib/arm-linux-gnueabihf/libpython2.7.so There is probably a "proper" way of fixing this, but I've managed to get this working by replacing the cmake command line in the article with these two:Ĭmake -DCMAKE_INSTALL_PREFIX="/usr/". When you try the import this gives the init failure message. ![]() This means the wrong init function is exported and the wrong python library linked. The cmake step for ftdi1 (on my system) correctly selects a python 2.7 install directory, but uses 3.0 headers and libraries. The Adafruit code is expecting python 2.7. Using CMake’s Official Website CMake’s official website has two options to install CMake on Linux as of now: A shell script (. I hit exactly the same problem yesterday when trying to follow the instructions in the FT232H article, on the latest Jessie OS.Īfter much banging of my head against a wall, I finally managed to figure out the problem is down to the cmake step getting a mix of python versions. To install cmake, g++ and make using the dnf command, type: sudo dnf install cmake gcc-c++ make Installing cmake using dnf 2. But how to figure out *what* has changed, that's a whole other matter.).Īnybody have current experience with this? This is the full path to the CMake executable cmake (1) which is useful from custom commands that want to use the cmake -E option for portable system commands. I can easily verify that all of the prereqs are installed (although, again, the fact that this tutorial is several years out-of-date on its Linux instructions suggests that many things could have changed and the prereqs no longer apply. The full path to the cmake (1) executable. Operating System: Win10 19042 CMake Version: 3.20.5 VSCode Version: 1.59. ![]() If I click on the setting option, It shows me: command 'lectBuildPreset' not found 3. What is clear is that the tutorial's instructions aren't lining up to reality. in my vscode, I can't set my cmake on my task tool bar, It shows me below: 2. I'm aware that there's a lot of things that *can* cause an importError of that sort, but I'm not a Python person, which makes it really impenetrable to sort out what the cause of the problem is. So there's not a lot you can do to kick the tires if you can't import it. Check the output, install the requested tool, and try again. I mean, specifically, it installs itself with "make install" but when you import the ftdi1 lib as the tutorial suggests, it barfs out on you complaining that the module doesn't define an init function. If you dont get the last line ( - Build files have been. which makes me feel like it hasn't been thoroughly tested.ī) The libftdi1 Python library doesn't seem to work. So I was trying to work on the Ft232H breakout tutorial ( ) and ran immediately into some software problems.Ī) The tutorial's got an obvious typo in the (Linux) installation instructions - a.
