Thanks for testing! Attached there is another .zip archive, with a Makefile to be replaced in *addon/lvgl/*. Please clean everything with `make clean` before trying to build. [Makefile.zip](https://github.com/user-attachments/files/19837313/Makefile.zip)

The Makefile workaround seems to work. Now we have a toolchain problem. The file *inttypes.h* must be provided by the toolchain. The file, which you have found in LVGL is...

Are you sure, that you are using the installed GNU C toolchain, which you have downloaded from the linked website? I think, you are using clang, which is different and...

@naturalmechanics I don't think, you can debug a Makefile that way, or I do not understand your intention. As I understand it, a Makefile is completely parsed, before the target...

@naturalmechanics Yes, at least at the moment.

What did not work with the default Makefile (any messages)? Please note that with the default Makefile it takes some time, until the build starts, because it has to collect...

The CM4 is special. You have to call configure with: ./configure -r 4 -d USE_XHCI_INTERNAL -d USE_EMBEDDED_MMC_CM and rebuild all. USE_EMBEDDED_MMC_CM enables the access to the eMMC memory of the...

There is a complete OpenVG 1.1 implementation for RPi 1-3 (32-bit) in Circle, which allows to do fast vector graphics. The C++ wrapper in libgraphics is far from complete, but...

@probonopd You are welcome. The RPi 4 or 5 must run in host mode, not gadget mode, and the USB audio interface must be connected, when the system is started...
