Build EdgeTX on M1 Pro MAC : arm-none-eabi-gcc error

[Batambatam]

Hi,

I am trying to build EdgeTX on a M1 Pro Mac and followed the instructions on this page :
https://github.com/EdgeTX/edgetx/wiki/Build-instructions-using-macOS-10.15-%28Catalina%29

Used this : cmake -DPCB=X7 -DPCBREV=TPRO -DCMAKE_PREFIX_PATH=$QTDIR -DGCC_ARM_PATH=/Applications/ARM/bin/ -DPYTHON_EXECUTABLE=/usr/local/bin/python3 ..

But I keep having this error when make firmware :

[ 16%] Building C object radio/src/targets/common/arm/stm32/bootloader/CMakeFiles/bootloader.dir/__/f2/system_stm32f2xx.c.o
arm-none-eabi-gcc: error: x86_64: No such file or directory
arm-none-eabi-gcc: error: unrecognized command-line option '-arch'; did you mean '-march='?
make[3]: *** [radio/src/targets/common/arm/stm32/bootloader/CMakeFiles/bootloader.dir/__/f2/system_stm32f2xx.c.o] Error 1

make[1]: *** [radio/src/CMakeFiles/firmware.dir/rule] Error 2
make: *** [firmware] Error 2

I do have the right CMakeLists.txt with CMAKE_HOST_APPLE
Tried setting an env variable CMAKE_HOST_APPLE=1 but no luck either.
Any help would be appreciated...
Thanks !

Try to set CMAKE_APPLE_SILICON_PROCESSOR to 'arm' before your build:

export CMAKE_APPLE_SILICON_PROCESSOR=arm

Thanks, I tried and I still get the same error.

Here are my env variables :

Are you building main or the 2.6 branch? I can build main on my M1 with this:

export QTDIR=/opt/homebrew/Cellar/qt@5/5.15.2_1
export CMAKE_APPLE_SILICON_PROCESSOR=arm
cmake -DPCB=X10 -DPCBREV=TX16S  -DCMAKE_PREFIX_PATH=$QTDIR  -DGCC_ARM_PATH=/Applications/ARM/bin/  ..

(and then a "make firmware" or which target I want to build)

[Batambatam]

I am trying to build main branch (2.7.0)
Damned, I used your cmake command and still getting the error.
I don't have the same version of QT than you, but I guess this is not a problem here.

I may start over and try again the whole procedure... I don't know.

[stephenaa]

Ahh, I have also added the ARM toolchain to my path: "/Applications/ARM/bin"

Try that :-)

[Batambatam]

OK I restarted from the beginning of the guide, now it's compiling the firmware
I think I screwed the installation of homebrew at the first try.

Thanks, I really appreciate that you take time to help me 👍

Now I try to build companion : everything compile then I have a linking issue.
CMAKE_APPLE_SILICON_PROCESSOR=arm is set.

I don't understand why it keeps compiling for x86_64...

Did you run cmake again in a clean directory?
I got it to work after some effort, but in the end it ended up being quite little that needed to be changed - and that should be on the 2.7 branch now.

[Batambatam]

I did a make clean and run cmake again.
I saw your PR was merged and you are several dev people that do not have issues since.

As I am still learning all this stuff of compiling on an arm Mac, it may be the reason why I am struggling to get it work.

Error seems to be about QT libraries, and 5.xx do not support Apple Silicon. Could it be the reason (I have Qt 5.12.9) ?
Or how do I compile for x86_64 target from my apple silicon ?

[Batambatam]

OK, I managed to build Companion and simulator.
I first built Qt5.15.3 libs for Apple Silicon.
I followed instructions on this page : https://eric-pierce.com/compiling-nextcloud-for-apple-silicon/
Then I also had to copy my SDL 1.2.15 libs (brew arm64-monterey version) to /usr/local/lib/

It's running native on my M1 now 👍

[stephenaa]

Good to hear that. They are nice machines, and pretty good development rigs 👍 Sendt fra min iPhone
