I think I may followed the wrong GitHub? `https://github.com/wasdwasd0105/picocalc-pi-zero-2?tab=readme-ov-file#guide-for-setup-pi-zero-2-on-picocalc` After installing the driver using ```auto cd ./picocalc-pi-zero-2 chmod +x ./setup_display.sh sudo ./setup_display.sh ``` I got this ```c -- Build files have been written to: /home/jblanked/picocalc-pi-zero-2/fbcp-ili9341-picocalc/build [14%] Building CXX object CMakeFiles/fbcp-ili9341.dir/display.cpp.o [14%] Building CXX object CMakeFiles/fbcp-ili9341.dir/dma.cpp.o [14%] Building CXX object CMakeFiles/fbcp-ili9341.dir/diff.cpp.o [19%] Building CXX object CMakeFiles/fbcp-ili9341.dir/fbcp-ili9341.cpp.o In file included from /home/jblanked/picocalc-pi-zero-2/fbcp-ili9341-picocalc/diff.cpp:6: /home/jblanked/picocalc-pi-zero-2/fbcp-ili9341-picocalc/spi.h: In member function ‘uint32_t* SPITask::DmaSpiHeaderAddress()’: /home/jblanked/picocalc-pi-zero-2/fbcp-ili9341-picocalc/spi.h:132:51: warning: taking address of packed member of ‘SPITask’ may result in an unaligned pointer value [-Waddress-of-packed-member] 132 | inline uint32_t *DmaSpiHeaderAddress() { return &dmaSpiHeader; } | ^ ~~~~~~~~~~~~ In file included from /home/jblanked/picocalc-pi-zero-2/fbcp-ili9341-picocalc/display.cpp:3: /home/jblanked/picocalc-pi-zero-2/fbcp-ili9341-picocalc/spi.h: In member function ‘uint32_t* SPITask::DmaSpiHeaderAddress()’: /home/jblanked/picocalc-pi-zero-2/fbcp-ili9341-picocalc/spi.h:132:51: warning: taking address of packed member of ‘SPITask’ may result in an unaligned pointer value [-Waddress-of-packed-member] 132 | inline uint32_t *DmaSpiHeaderAddress() { return &dmaSpiHeader; } | ^ ~~~~~~~~~~~~ In file included from /home/jblanked/picocalc-pi-zero-2/fbcp-ili9341-picocalc/dma.cpp:12: /home/jblanked/picocalc-pi-zero-2/fbcp-ili9341-picocalc/spi.h: In member function ‘uint32_t* SPITask::DmaSpiHeaderAddress()’: /home/jblanked/picocalc-pi-zero-2/fbcp-ili9341-picocalc/spi.h:132:51: warning: taking address of packed member of ‘SPITask’ may result in an unaligned pointer value [-Waddress-of-packed-member] 132 | inline uint32_t *DmaSpiHeaderAddress() { return &dmaSpiHeader; } | ^ ~~~~~~~~~~~~ [23%] Building CXX object CMakeFiles/fbcp-ili9341.dir/gpu.cpp.o [28%] Building CXX object CMakeFiles/fbcp-ili9341.dir/hx8357d.cpp.o /home/jblanked/picocalc-pi-zero-2/fbcp-ili9341-picocalc/gpu.cpp:1:10: fatal error: bcm_host.h: No such file or directory 1 | #include // bcm_host_init, bcm_host_deinit | ^ ~~~~~~~~~~~ compilation terminated. make[2]: *** [CMakeFiles/fbcp-ili9341.dir/build.make:132: CMakeFiles/fbcp-ili9341.dir/gpu.cpp.o] Error 1 make[2]: *** Waiting for unfinished jobs....
