Manjaro Distro
Dear all,
I switched to Manjaro a few weeks ago. Now I'm trying to build NuttX - of
course.
This packages where necessary so far:
sudo pacman -S ncurses base-devel gmp mpfr libisl elfutils expat
lib32-gcc-libs uboot-tools unzip
# Install genromfs as per PX4
wget
https://sourceforge.net/projects/romfs/files/genromfs/0.5.2/genromfs-0.5.2.tar.gz
tar zxvf genromfs-0.5.2.tar.gz
cd genromfs-0.5.2 && make && make install && cd ..
rm genromfs-0.5.2.tar.gz genromfs-0.5.2 -r
--
I cannot resolve the following error:
fatal error: math.h: No such file or directory
NuttX documentation says:
The math library header file, `math.h`, is a then special case. If you do
nothing, the standard math.h header file that is provided with your
toolchain will be used.
Can somebody please give me a hint for how to overcome this?
Best regards,
Simon

Yes on this. Distribution provided bare metal arm toolchains have always
been a disappointment for me.

On the libm: some time ago I tried to install the RISCV toolchain on Ubuntu
with apt and the installed toolchain was built without libm :)
In other words, running compiler + arch flags with "--print-file-name=libm.a"
option gave me an empty output (also "find gcc_folder -name libm.a" gave me
an empty result).
I think the best way is to install GCC from the ARM website and not using
OS package manager.
For the romfs error, maybe you can try to track romfs generation path and
try running it manually from console instead of running it from make. I
think it would be easier to narrow down an issue by executing steps
manually from the console.
Best regards,
Petro

Hi all,
thanks for answering.
I'm still in build-phase. No runtime hard-fault. I'm using my fork on
github https://github.com/SimonFilgis/incubator-nuttx
Mr. Xiao nailed it. It choose to use the NuttX internal libm for the moment.
But still something seems to miss, please have a look at the attached log.

Again romfs_img, I had this with the bitbucket pipeline a few days ago, xxd
was missing. I cannot identify root cause with make V=1 (attached).
Has anybody an idea?

It would be helpful to understand where and why the crash occurs too.
You can get that information by analyzing the stack. See
https://cwiki.apache.org/confluence/display/NUTTX/Analyzing+Cortex-M+Hardfaults
for an example.
Without know why the hard fault occurs that is nothing anyone can really
do or say to be helpful (unless the problem can be replicated).

Hi,
I think that some key information is missing like what is the NuttX version
used. Is it mainline or some release or custom.

Which toolchain do you use? You have two choices now:
- CONFIG_LIBM=y which enable libm provided by nuttx
- CONFIG_LIBM_TOOLCHAIN=y which select libm provided by toolchain
New selection will come soon, e.g.:
https://github.com/JuliaMath/openlibm
https://gitlab.com/gtd-gmbh/libmcs
