mayo on aarch64

[KascheyBessmertnii]

Hello!

I tried to build this project for a processor based on ARM64 architecture for Linux (armv8, cortex A57, aarch64)

When trying to build i have an error which says "Platform architecture not supported (QT_ARCH=arm64)"

Could you specify is there a version suitable for building on ARM64 archtecture? Or do you have any ideas at which direction to look to solve it? I didn't have experience working with !t before, so maybe its some simple configs somewhere in the project

Hello Kaschey! Thanks for having reported this issue. This is a somewhat "forced" error that is located in file opencascade.pri This is too restrictive, I should turn this error() statement into a warning() Try to remove that line (or comment it with #) and run qmake again. Let me know the results of this, that's interesting. By the way did you manage to install OpenCascade packages on your Linux system ?

Thanks for the tip, Changing error to warning helped to install Mayo on Alt Linux 10 (aarch64) on armv8-a processor. I also had to add in method

QStringQStringUtils::yesNoText(CheckState state) ( mayo/src/app/qstring_utils.cpp ) default: return tr("No");

After this it compiled. But when i tried to open step file (tried on other PCs with mayo it worked great) around 20 megabytes an error occures. A branch treee of elements works good, but the model itself doesnt render

At least it compiles that's a good point. What is the Qt and OpenCascade versions you are using ? What C++ compiler ?

[KascheyBessmertnii]

Qt - 5.15.2 OpenCascade - 7.5.3 gcc - 10.3.1

[HuguesDelorme]

No problem with that configuration then. If you run debug build of mayo don't you see any OpenGL warning in the console output ?

[KascheyBessmertnii]

yep. see next warning - OpenGL_Window: CreateWindow: window Visual is incomplete: no depth buffer, no stensil buffer

[HuguesDelorme]

What you could do is trying to run some official OpenCascade samples and see if it works. This will tell us if those graphics problems are specific to Mayo or not

[CheLoV]

Greetings! Were there any updates. Also encountered troubles with aarch64 builds

[HuguesDelorme]

Hello @CheLoV Did you try to run some official OpenCascade example on your arm64 OS ?

[HuguesDelorme]

@KascheyBessmertnii and @CheLoV Do you still experience this problem with latest version(v0.7.0)? Let me know your feedback if any, thanks
