Can't compile TinyUSB examples

[tobias-groeger]

When trying to execute cmake for pico-examples I get the following error:

CMake Error at .../pico-sdk/lib/tinyusb/examples/host/msc_file_explorer/CMakeLists.txt:13 (add_executable):
  Cannot find source file:

    /lib/fatfs/source/ff.c

  Tried extensions .c .C .c++ .cc .cpp .cxx .cu .mpp .m .M .mm .ixx .cppm .h
  .hh .h++ .hm .hpp .hxx .in .txx .f .F .for .f77 .f90 .f95 .f03 .hip .ispc

Upon further investigation I found that the TinyUSB examples are added from the the submodule in the pico-sdk. In the msc_file_explorer example in $PICO_SDK_PATH/lib/tinyusb/examples/host/msc_file_explorer/CMakeLists.txt some of the source files are added relative to the ${TOP} cmake variable which isn't set so the files aren't found properly.

I am running gcc version 12.2.0 and cmake version 3.26.3.

Also trying to execute cmake -G "NMake Makefiles" .. and get the same result:

i had the same problem, i solved it by:

1. downloading the module from the website faftfs
2. move it in the folder pico/pico-sdk/lib
3. change it's name to fatfs since the CMakelist file was searching for that
4. inside the same CMake file avaiable at /pico/pico-sdk/lib/tinyusb/examples/host/msc_file_explorer substitute the {TOP} in the path for the fatfs with the PATH_SDK_PATH
5. once in the folder pico-examples set it on the terminal with the command PICO_SDK_PATH=../../pico-sdk/
6. finally launch the cmake command cmake -DPICO_BOARD=pico_w ..

what version of SDK? have you updated the TinyUSB version to something different to what the SDK ships with

Did get this issue after a hiatus, had done a git pull on the sdk but not the examples repo. Updating examples did the trick.
