macOS arm-none-eabi build error

[fred-corp]

I'm trying to build the code on macOS; everything works well until I get to this point :

[ 78%] Linking CXX executable RS41ng.elf
/opt/local/lib/gcc/arm-none-eabi/12.1.0/../../../../arm-none-eabi/bin/ld : arm-none-eabi/bin/ld : Error: unable to disambiguate: -search_paths_first  (did you mean --search_paths_first ?)

make[2]: *** [src/RS41ng.elf] Error 1
make[1]: *** [src/CMakeFiles/RS41ng.elf.dir/all] Error 2
make: *** [all] Error 2

I had to specify my TOOLCHAIN_PATH in src/CMakeLists.txt to be /opt/local/bin before running cmake .. because the arm-none-eabi-gcc toolchain is apparently installed there on macOS.

How could I fix this issue ?

Edit : I installed the toolchain with MacPorts, which compiled it on my machine

Some progress :
I installed the toolchain with HomeBrew instead of MacPorts (it is now in /usr/local/bin).
Now the error message shows something else :

[ 78%] Linking CXX executable RS41ng.elf
arm-none-eabi-g++: error: RS41: No such file or directory
arm-none-eabi-g++: error: RS41ng/build/RS41ng.map: No such file or directory
make[2]: *** [src/RS41ng.elf] Error 1
make[1]: *** [src/CMakeFiles/RS41ng.elf.dir/all] Error 2
make: *** [all] Error 2

There seems to be a file missing, I'll try to investigate on that

[fred-corp]

Issue fixed, I had spaces in the folder name...

The build still gives out errors before setting to 100%, apparently I need libbsd-devel, which I could not install on my machine...

I built the program with the Dockerfile @MrARM made (linked to this pull request), and it works great !

@fred-corp Ok, thanks for the report -- unfortunately I don't have a Mac to test the build.

Did the Dockerfile and its environment work for you or did you need to do some changes to it? What was the comment about libbsd-devel?

libbed-devel error

This is the error I get :

the .elf file gets made, but I'm missing bsd/string.h which I figured is part of libbsd-devel.

Docker build environment

I just changed the following lines in docker_build.sh from this :

# Copy the binary, ELF and hex to the home directory
cp src/RS41ng.elf /usr/src/rs41ng
cp RS41ng.hex /usr/src/rs41ng
cp RS41ng.bin /usr/src/rs41ng

to this :

# Copy the binary, ELF and hex to the home directory
rm -rf /usr/src/rs41ng/build/
mkdir /usr/src/rs41ng/build/
cp src/RS41ng.elf /usr/src/rs41ng/build/
cp RS41ng.hex /usr/src/rs41ng/build/
cp RS41ng.bin /usr/src/rs41ng/build/

So the container automatically replaces the old build files with new ones in a build directory.

Then I just ran the following commands to create the container and build the code (as mentioned in @MrARM 's README) :

docker build -t rs41ng_compiler .
docker run --rm -it -v $(pwd):/usr/src/rs41ng rs41ng_compiler

Finally, I can flash the .elf with openOCD :

openocd -f ./openocd_rs41.cfg -c "program build/RS41ng.elf verify reset exit"

And it works a treat !
