I am trying to compile Marlin 2.1.x for Creality Ender 3 Pro on my Octopi, and I keep getting a segmentation violation on cc1plus. I have opened
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108249
and they are asking for the full command line which is failing, but I don’t know ow to get platformio to show that to me - is there a log somewhere? I’ve provided the “build_flags” but that doesn’t seem to meet the requirement. I added “-Wall -Wextra” to the build flags, but I still don’t see any preprocessed files.
Project tasks → Advanced → Verbose build.
Or, more directly on the CLI
pio run -t clean
pio run -v -j1 > build_log.txt 2>&1
(for Windows, redirects stderr to stdout which is then logged into the file.)
OK. I did that, but I still don’t see the actual infocation of cc1plus (or g++ or whatever entry point they used). I’d attach the file, but I don’t see how to do that. So - I guess I’ll call it preformatted text and paste it in here:

Then the fault does not originate from directly building a C/C++ source file as part of the firmware, but from from one of Marlin’s extra_scripts invoking the compiler.
One such place could be
so just change this variable to 1
in your Marlin files and retry.
OK. I actually found that in

My understanding of what platformio is doing at this point is clearly deficient. Did it install its OWN version of gcc? That arm-none-eabi-g++ is a substantial program in its own right - I figured it would just be a script to invoke the system g++, but that’s not the case:
pi@octopi:~/Marlin $ file "/home/pi/.platformio/packages/toolchain-gccarmnoneeabi/bin/arm-none-eabi-g++"
/home/pi/.platformio/packages/toolchain-gccarmnoneeabi/bin/arm-none-eabi-g++: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 3.2.0, BuildID[sha1]=fd0d803f6ff2b3e11940e36071c0b1f65d1860bf, not stripped

The entire point of PlatformIO is providing the ecosystem for compiling firmwares with no requirements of preinstalled compilers. PlatformIO downloads the toolchain-gccarmnoneeabi package from the PlatformIO trusted registry, where the PlatformIO staff has initially uploaded the compiler packages and lots of other packages too. PlatformIO does not use the system compiler when compiling embedded firmwares as it cannot be assumed the system has that installed. The only exception of that is when you explicitly tell PlatformIO to build for your native system with the native toolchain, i.e., platform = native.
And even more, when you want to create a program for an an ARM Cortex Mxx ARMv7e-M based microcontroller (M3, M4, …), you have to use a compiler that can create binaries for that target architecture while running on your computer’s native architecture, aka a cross-compiler. That’s what arm-none-eabi-gcc is. Using the raspberry pi’s compiler it would just produce a linux-native and ARMv6/7/8 / AArch64 (depending on the used Pi) native binary, that is of absolutely no use for the ARMv7e-M based microcntroller that is supposed to be running the produced firmware.
I understand the need to cross-compile. I thought gcc had been expanded years ago to be able to cross-compile for multiple architectures just by specifying different “back ends” to produce the code. I apologize for my misunderstanding on that point. I’ve come upon this whole PlatformIO business simply out of my need to compile Marlin for my 3D printer, and I’m learning as I go.
That brings me to an interesting situation. The GNU bug report I created is wrong. The cc1plus that is doing the segmentation fault is NOT the system installed cc1plus, but probably this one:
./.platformio/packages/toolchain-gccarmnoneeabi/libexec/gcc/arm-none-eabi/9.3.1/cc1plus
Yeppers. The moment I try to invoke the above, I get the segmentation fault - even with no parameters at all. Can I easily remove and reinstall that? Could it have gotten corrupted during the installation? Since this is an encapsulated distribution where do I go to try to figure this out? Do I delete my gnu bug report, or try to change it to cover this version?
Same segfault with
~/.platformio/packages/toolchain-gccarmnoneeabi/bin/arm-none-eabi-g++ --version
?
No.

Okay but that part works. I’m not sure whether you’re supposed to execute cc1plus directly at all like this.
What’s the output of this command? That’s closer to what Marlin would do, but with an empty input file.
~/.platformio/packages/toolchain-gccarmnoneeabi/bin/arm-none-eabi-g++ -w -dM -E -x c++ /dev/null
Does it segfault or print tons of #defines?
Just segfaults.

Note that when I execute the system installed cc1plus, it just sits waiting for input, or I can run it with “–version” and it silently exits. If I take a “–version” on the end of the toolchain cc1plus, it still segfaults.
Okay, but then this is your minimal example, and that’s with
Sorry - is there an implied action or question here? Not sure what you want me to do at this point.
No, it was just a statement to help on your bug report. That’s the most minimal way to reproduce the error you’re getting, as we’ve found out.
Bug report for GNU? Or whoever is supporting this toolchain? If the latter - how do I reach them? And just to be as rigorous as possible - how would I remove that toolchain and reinstall it?
I think since it’s GCC the bug report in gnu.gcc.org is okay.
From your Marlin project folder:
rm -rf ~/.platformio/packages/toolchain-gccarmnoneeabi
rm -rf ~/.platformio/.cache
pio run
You rock! After removing and reinstalling, it’s compiling! THANK YOU for your kind help and patience with a newbie! How that program got corrupted may remain forever a mystery, but as long as this works, I don’t care.
With all the “verbose” settings, I got literally thousands of warnings in the form of
Marlin/src/HAL/STM32/../../inc/Conditionals_post.h:2177:1: warning: this use of "defined" may not be portable [-Wexpansion-to-defined]
but those went away after I turned off the verbose settings. I got some errors about dependent features that needed to be #defined for my config, so I turned those on. … and …
