32 bit apps supported?
#1
I was wondering if pureos or mobian will support 32 bit apps in the future?

Thanks!

What are you hoping to run that doesn't have a 64bit version available?

The toolchain I use (Xojo) only supports building 32 bit ArmV7 apps ATM.

Is it hard to add support?

I suggest you file an enhancement request - the worst they can say is WONTFIX and then at least you know!

I think it depends on what level of support you're looking for. As I understand it (and I may not!) the bare minimum is a kernel that supports 32 bit ('Userspace binary formats ---> Kernel support for 32-bit EL0' in menuconfig). That's the easy part, but should be enough for static executables. The problem comes with libraries etc. as AFAIK there isn't an arm equivalent of the 32 bit compatibility libraries we have for x86/x86_64. If Debian supports that then Mobian probably will, and likewise for PmOS and Alpine linux.

You can try running your app through QEMU. It does have support for armhf

The xojo forums has a thread tracking the issue; Looks like it will come soon, there's also a post in the thread that mentions a wrapper workaround that might work for you.

Thanks for the tips. I saw that too.

Problem is the adding the armhf architecture only causes apt-get to error when trying to find libraries.
