Hi,

So just `sudo apt-get install ...` of the above.
Please try to remove "CFLAGS += -lm " and feedback if that helps.
No change.
The problem is not that I am trying to use some released libm library
but that the NuttX nuttx/libs/libm/libm.a is not being linked into the
scheme binary file.
I have not used other than trivial makefiles in a couple of decades,
never used `make menuconfig`, which allows one to specify many
non-bootable systems, and so have little clue how to specify linking the
NuttX libm into the scheme executable or alternately getting nuttx to
dynamically load the libm library.
Note that there is no file 'kconfig-language.txt' in the NuttX tools
repository.
I am kinda stuck. Thanks for any help!
