SIGSEGV when compiling for custom boards

[Renaud11232]

I noticed a problem when I try compiling a sketch for a custom board.

~$ ./arduino-cli compile --fqbn anet:avr:anet Marlin/
panic: runtime error: invalid memory address or nil pointer dereference

The problem does not appear when arduino:avr is installed.

[per1234]

Please provide instructions for how you installed the anet:avr package so we can attempt to reproduce the issue.

Does the issue only occur when you're compiling Marlin, or does it also occur if you are compiling a minimal sketch like examples/01.Basics/BareMinimum?

[Renaud11232]

Hello,
I've downloaded the anet:avr package here and placed the content of the hardware folder into ~/Arduino/hardware
Once that was installed i just ran ./arduino-cli compile --fqbn anet:avr:anet Marlin/ wich gave me the error.
The issue also occur when I try to compile BareMinimum.
The problem also exists on Windows with the package installed in C:\Users\gaspa\Documents\Arduino\hardware, also failing with BareMinimum.

void setup() {
}

void loop() {
}

PS C:\Users\gaspa\Downloads> .\arduino-cli.exe compile --fqbn anet:avr:anet .\BareMinimum

I also tried with custom boards installed with the boad manager. To try that I added the sanguino package index from here into arduino-cli.yaml, then updated the index with ./arduino-cli core update-index, then installed the sanguino boards with ./arduino-cli core install Sanguino:avr.
Once it was installed I ran ./arduino-cli compile --fqbn Sanguino:avr:sanguino BareMinimal/. This gave me the same error.

I hope it will help.

[zmarcantel]

I can confirm the same behavior, using multiple custom boards/cores, both with Marlin and the basic example.

I tracked down the source of the segfault but still trying to fully understand (and hopefully get a PR up, but fighting dep with forks and such).

To further complicate things -- a workaround is to install any arduino:{proc} core.
After running arduino-cli core install arduino:avr all the nils below are valid (visual inspection, have not tried flashing). So there's clearly something with silently erroring or not being checked around custom board directories.

The issue starts here:

github.com/arduino/arduino-builder.(*LibrariesLoader).Run(ctx *types.Context) error

The context passed is nil for ctx.ActualPlatform which ends up being used (in that function) here:

59:		actualPlatform := ctx.ActualPlatform
60:		platform := ctx.TargetPlatform
61:		if actualPlatform != platform {
62:			lm.AddPlatformReleaseLibrariesDir(actualPlatform, libraries.ReferencedPlatformBuiltIn)
63:		}

where the call to AddPlatformReleaseLibrariesDir uses the actualPlatform arg immediately, assuming non-nil:

func (sc *LibrariesManager) AddPlatformReleaseLibrariesDir(plaftormRelease *cores.PlatformRelease, location libraries.LibraryLocation) {
   138:		path := plaftormRelease.GetLibrariesDir()

which triggers the segfault (as platformRelease is nil).

[zmarcantel]

Some more tracking down makes it seem the Sanguino requires the arduino package to be installed -- which makes the above workaround make sense at least.

func (pm *PackageManager) ResolveFQBN(fqbn *cores.FQBN) (....)

// sanguino has "arduino:arduino" for "build.core"
184:		coreParts := strings.Split(buildProperties.Get("build.core"), ":")

...

// this is valid, and looks like the standard "arduino" package
192:			buildPlatform := buildPackage.Platforms[fqbn.PlatformArch]
193:			buildPlatformRelease = pm.GetInstalledPlatformRelease(buildPlatform)

... but then we try to get the installed packages:

func (pm *PackageManager) GetInstalledPlatformRelease(platform *cores.Platform) *cores.PlatformRelease {
322:		releases := platform.GetAllInstalled()
323:		if len(releases) == 0 {
324:			return nil
325:		}

(dlv) p releases
[]*github.com/arduino/arduino-cli/arduino/cores.PlatformRelease len: 0, cap: 0, []

which bubbles all the way out to LibraryLoaders context not having an ActualPlatform set.

[QuinnFreedman]

I can confirm that I'm getting the same problem trying to work with Adafruit boards on a clean install. As @zmarcantel suggested, running arduino-cli core install arduino:avr fixed it. This definitely needs a better error message at the very least though

[masci]

I wasn't able to track the exact commits but this is fixed now:

» ./arduino-cli compile --fqbn anet:avr:anet Marlin/

[Renaud11232]

Hello, is the fix for this issue included in 0.6.0 ?

Because I tried the same thing I decribed above and got this :

arduino-cli core update-index --additional-urls https://tician.github.io/arbotix/package_trossen_arbotix_index.json
cd /tmp && arduino-cli sketch new MyFirstSketch
arduino-cli -v compile --fqbn arbotix:avr:arbotixAd MyFirstSketch

Result:
