ngrok does not work on *WRT routers environment with error Illegal instruction

[muchacho777]

Hi,

https://bin.equinox.io/c/bNyj1mQVY4c/ngrok-v3-stable-linux-mips.tgz
Using this binary dated Aug 28 I am getting error:

./ngrok
Illegal instruction

Some extra info about binary:
file ngrok
ngrok: ELF 32-bit MSB executable, MIPS, MIPS32 version 1 (SYSV), statically linked, BuildID[sha1]=5bbe0fb9da1c640d76a50f50d2c6e41ecf59bad2, stripped

md5sum ngrok
6f5866b523a82c7179f4fb860b02117a ngrok

LDD does not provide any useful info so it is absolutely unclear what are the depedencies for ngrok. In my case mips_24kc architecture is used and I have successful experience running other Go binary (not ngrok) with similar specs: ELF 32-bit MSB executable, MIPS, MIPS32 version 1 (SYSV), statically linked

Also I see closed similar issue without any resolution:
inconshreveable/ngrok#890

Could you please explain what are the possible reasons for Illegal instruction error, and what could be done to fix it?

Hi @muchacho777 -- I suspect this could be an instruction set mismatch with your router. Our library is (as mentioned in your report) statically linked, so there is no expectation that ldd provide any meaningful data.

If you could provide your router's make, model, firmware version (and, if available, the output of /proc/cpuinfo this could give a bit more info to investigate along
