Problem compiling & linking

[Zambiorix]

Hi all

I have followed all instructions on how to start with RepRapFirmware development environment on macos.

https://github.com/Duet3D/RepRapFirmware/wiki/Building-RepRapFirmware

The only difference, I didn't use homebrew, but installed gcc-arm-embedded from package (https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads) and eclipse from direct installer.

All the other steps are the same.

CoreN2G, FreeRTOS and RRFLibraries build just fine.

RepRapFirmware (build configuration Duet3_MB6HC) however gives me errors.

It seems that uint32_t is undefined, so I add:

#include <stdint.h>

in src/libc/nano-mallocr.c

That gives me the following error:

Now there are multiple definitions of _malloc_r

Renaming src/libc/nano-mallocr.c to src/libc/nano-mallocr.c.ignore leaves me with:

I have no idea where to look next.

Also, I suppose it's not ok to remove src/libc/nano-mallocr.c , but then again, why did it say that uint32_t is undefined in the first place?

Am I missing some setup?

Thanks
Cheers

Gerd

@Zambiorix we think the issue with multiple definitions of _malloc_r occurs when you use a later version of gcc than the one we currently use. We currently use ARM release 10 2021.10. We'll probably update to a later version before 3.5 final.

@dc42

Thanks! That solved it, now the project build without errors.

/bin/sh: crc32appender: command not found

That is strange, I have added it to my PATH

gerd@Gerds-MacBook-Pro ~ % whereis crc32appender
crc32appender: /Users/gerd/Documents/Projects/Projects/Duet3D/RepRapFirmware/Tools/crc32appender/macos-x86_64/crc32appender

What could be the issue?

Ok, it all works

I had to add the PATH in Eclipse.

Project > Properties > C/C++ Build > Environment

Not sure why I had to do that, since the application is accessible in a terminal window
