dell latitude d620 intel core duoAnswered

Hi Wyatt,

on this laptop running a linux Mint 20.1 I got a segfault with my app (using latest TA from December 2020):

#0  0x00007feb77784b38 n/a (/home/mekol/app/myapp_mint/bin/libTurboActivate.so + 0x3db38)

is there's restriction on Linux regarding hardware?

best regards,

Mint uses musl libc instead of glibc (while pretending to be glibc). This is broken behavior that we don’t support.

Use a mainstream Linux distro.

thank you for your answer.

I've installed Mint20.1 on a VM and libc report to be glibc…

Is there's a way to know if it's true?

also, maybe TA should not crash the app but report that the OS is not supported.

so based on tests with my customers it appears that:

TA from 2020/07/10 does work on Ubuntu AND linuxMint20.1

TA from 2020/12/15 fails on Ubuntu AND linuxMint20.1 (it crash my app)

do you plan to investigate on this?

by the way:

Hi,

the real reason seems not to be related to libc but that the CPU of this computer doesn't know anything about SSE4.2.

Answer

Right. We dropped support for CPUs not supporting those instructions (on Unix) about a year ago.
