Getting a segmentation fault

[omidnezami123]

Hey,

Just spent most of my day getting this set up on Windows. I've got it compiling however, but when I try to run the executable, I'm getting a segmentation fault.

The only thing I've changed is the biosim4.ini, so here's how that looks like:

numThreads = 10


sizeX = 128
sizeY = 128

population = 1000

stepsPerGeneration = 300

maxGenerations = 10

genomeInitialLengthMin = 20
genomeInitialLengthMax = 20
genomeMaxLength = 300

maxNumberNeurons = 3

killEnable = false

sexualReproduction = true

chooseParentsByFitness = true

pointMutationRate = 0.001

geneInsertionDeletionRate = 0.0
deletionRatio = 0.5

responsivenessCurveKFactor = 2

populationSensorRadius = 2.5

longProbeDistance = 24

shortProbeBarrierDistance = 4

signalSensorRadius = 2.0

signalLayers = 1

imageDir = images

logDir = logs

displayScale = 8

agentSize = 4

videoSaveFirstFrames = 2

updateGraphLog = true

saveVideo = true

videoStride = 25

updateGraphLogStride = videoStride

genomeAnalysisStride = videoStride

genomeComparisonMethod = 1

displaySampleGenomes = 10

challenge = 17

barrierType = 0

replaceBarrierType = 0
replaceBarrierTypeGenerationNumber = -1

Here's the last part of the output from the terminal as well:

Segmentation fault

Would really appreciate some help with this.

Also, want to thank David for posting this video. Easily one of my favorites on the platform today.

I'm a CS guy, but I found the intersectionality with biology fascinating. The complexity of a brain with only a couple of neurons leaves me in awe of how complicated our brains must be.

By "Windows", do you mean "Windows 11 using WSL"? I've had this combo running without any problems. (And without any changes to source code or configuration.)

I would personally be skeptical of trying to modify this project to create a Windows native version, because it depends on quite a few Linux libraries and I would expect that the main stream of development will apply to the Linux version (native, WSL, VM, Dockerized, whatever). It would be, er, "challenging" to keep the Windows native fork up to date. And with WSL the project is easily accessible to Windows users.

I'm using Windows 10 with WSL. Yeah, I realized after cloning it locally that the Windows native version had some issues, so I recloned the project in WSL (Ubuntu v21.04).

Thanks for the input though.

might I suggest trying docker (#8)? I've published images that can compile + execute and have tested them on everything except WSL / Windows, but would love feedback on whether or not it changes anything about your segfault error.
