I am trying to install sdr++, but I dont think that matters. after installing the nightly apt package on my rpi 4, I attempted to run the main bianary sdrpp but got a file not found error:

pi@sdr:~ $ /usr/bin/sdrpp
-bash: /usr/bin/sdrpp: No such file or directory
pi@sdr:~ $ ls -li /usr/bin/sdrpp
43166 -rwxr-xr-x 1 pi pi 8144 Jul 23 23:58 /usr/bin/sdrpp

As far as I can tell there arent any strange chars (ѕ vs s, diffrent chars but look alike)
These two commands were exicuted shortly after one another, so its not like the file was suddenly created
Still happens after a restart
I think I got this same bug a long time ago trying to run rust in a replit, I never fixed it.
File reports it as a ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, BuildID[sha1]=c4fea3dbc91de8553d404ed70b214efe2a234f39, for GNU/Linux 3.2.0, not stripped and im pretty sure that's accurate

Other info:

pi@sdr:~ $ uname -a

Does this answer your question? [No such file or directory? But the file exists!](https://askubuntu.com/questions/133389/no-such-file-or-directory-but-the-file-exists)

I think this is relevant, because you are trying to run a 32-bit executable in a 64-bit system.

i will try this

@MechMK1 i suspect this may be an issue on part of sdrpp, as they ship a 32-bit exe that has mandatory 64-bit dependencies.

What does `/lib/ld-linux-armhf.so.3 /usr/bin/sdrpp` do? If it says `/lib/ld-linux-armhf.so.3` is not found, then you do not have 32-bit support.

@makerio Would compiling it yourself from source be an option?

rando

@makerio I would highly recommend compiling from source. The nightly build never worked for me, and it only took ≈ 20 mins on my system. However, I think this question belongs on the Raspberry Pi Stack Exchange.

@rando I'm so used to posting to Ubuntu i didn't even realize there was a rpi stack exchange. plus, I've been having even more trouble installing sdrpp on 32bit raspbian. did you use 32 or 64 bit raspbian?

64-bit Raspberry Pi OS

As it seems you've solved your problem, please close this question.

to those coming from google, sorry as i don't have an answer for you.

this problem was circumvented by abandoning sdrpp for a similar program.

thank you to @rando for noting that i may have been missing a library (and i suspect that that was the issue), suggesting that i compile from source.
thank you to @MechMk1 for noting that i had attempted to run a 32 bit executable on a 64 bit machine.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
