librespeed/speedtest-cli

Not working on Mips architecture (openwrt)

I'm trying to run speedtest-cli 1.09 on a GL-X750 LTE router.
I tried both the -mips-hardfloat and -mips-softfloat binaries, but both stall shortly after starting with no console output.
Strace shows:

Am I using the right binaries ? From what I can see I don't have a 64bit architecture.
What's the difference between -softfload and -hardfloat, and between -mips and -mipsle` ?

@maddie Thx, I tried using upx but it doesn't start neither. I downloaded https://github.com/upx/upx/releases/download/v3.96/upx-3.96-mips_linux.tar.xz to my laptop, extracted the archive using tar -xJf upx-3.96-mipsel_linux.tar.xz and copied the upx binary to the router. There it stalls at the same stage, wonder what I'm doing wrong:

Well I just found that this is a know issue with upx and their latest release doesn't work on mips :/

varac commented

Ooh, nice I uncompressed it using upx on my laptop and now it works ! Thx @maddie for the hint. Might be good to document this in the README.

No problem. I'll close this issue as fixed.
