Did you enable CONFIG_LIBM in the menuconfig?
Normally it is enough if your arch correctly configured.
Yep. Enabled.
I added
LDLIBS += $(APPDIR)/../nuttx/libs/libm/libm.a
to the Makefile and the Scheme interpreter works -- some console

OK.
Unfortunately the menuconfig is not prepared (better say it cannot) to
fix all dependencies for an driver or application (because of the
flexibility to use

I just used menuconfig interpreters bas selection
Raspian:RasPi4:~/RISCV/NuttX/nuttx >>> grep CONFIG_INTERPRETER_BAS
.config
CONFIG_INTERPRETER_BAS_VERSION="2.4"
Hi Ken,
Are you enabling the same symbols as in the sim bas or bastest ?
$ cd nuttxspace/nuttx
$ cd boards/
$ git grep "BAS=y"
sim/sim/sim/configs/bas/defconfig:CONFIG_INTERPRETERS_BAS=y
sim/sim/sim/configs/bastest/defconfig:CONFIG_INTERPRETERS_BAS=y
$ cd ..
$ ./tools/configure.sh
Ah. I tried using `make menuconfig` to build the Basic interpreter.
Raspian:RasPi4:~/RISCV/NuttX/apps >>> riscv64-linux-gnu-gcc-nm -u
bin/bas
U atan
U ceil
U cos
U exp
U floor
U fmod
As I am building on aarch64/arm64 Linux, someone might have a better
time with x86.
I made a git repo:
https://github.com/KenDickey/nuttx-umb-scheme
This goes into apps/interpreters.
The code has been reliably ported a lot and should run on most targets
with command line console.

Here's what Ken and I have tried for the riscv64 libm linking problem:
(1) The recommended toolchain for NuttX on riscv64 is SiFive Freedom Tools.
But it doesn't support Raspberry Pi OS (64-bit Debian).
(2) So we used Debian gcc-riscv64-unknown-elf instead. Which shows the
missing libm error

Hi,
What kind of RISC-V toolchain are you using? I recall that the RISC-V
toolchain provided by Ubuntu is built without libm support. Also I noticed
that you have "CFLAGS += -lm " in Make.defs and with CONFIG_LIBM=y that
should be removed I think as you try to rebuild math from NuttX sources.
Please forgive the noob question.
I am porting a Scheme interpreter to riscv64 NuttX as
apps/interpreters/umb-scheme/ but the binary fails to link in libm
functions.
I could use some help in this.
Specifically, building on Raspberry Pi 4 Raspian 64 bit:
