flent dependency on matplotlib but latter not compiling, apparently Cython failing to compile in the first place [1].

Anyone got flent working in the aforementioned environment?

Appears to be some causality:

  • flent functionally depends on matplotlib
  • matplotlib functionally depends on numpy
  • numpy depends on gcc being installed

File “numpy/core/setup.py”, line 661, in get_mathlib_info
raise RuntimeError(“Broken toolchain: cannot link a simple C program”)
RuntimeError: Broken toolchain: cannot link a simple C program
Preparing wheel metadata: finished with status ‘error’

And finally gcc does not install because it collides with busybox

Collected errors:

  • check_data_file_clashes: Package binutils wants to install file /bin/strings
    But that file is already provided by package * busybox
  • opkg_install_cmd: Cannot install package gcc.
