Linux IDE issue

having a slight problem with the IDE suite when compiling in Linux.
i have installed all the drivers (i think) that is needed to upload to the proffie but i keep getting this strange error message.
i’ve checked that the files are where it seems to be looking for them but for the life of me i just cant figure it out why it wont see them? (i’m sure it’s a simple fix)

i can see the board in ports when plugged in and i can also see the SD card so doesn’t appear to be a issue with that part.

Arduino: 1.8.19 (Linux), Board: "Proffieboard V2, Serial + Mass Storage + WebUSB, SDCARD (SPI), 80 MHz, Smallest Code"

fork/exec /home/driftrotor/.arduino15/packages/proffieboard/hardware/stm32l4/3.6.0/tools/linux//dfu-suffix: no such file or directory

Error compiling for board Proffieboard V2.

any help is happily received.

Does that file exist?

it does, i traced the path specified and found what should be there.
but for some reason it is not seeing it.
this is why i am confused.

if you go to that directory and run ldd dfu-suffix, what do you get?

when you say “run” do you mean double click?
if so i get nothing and right click does not give me an option to run either.

No, I mean type “ldd dfu-suffix” into a terminal.

it says “no such file or directory”

so this leads me to assume that it is not in the correct place.

if i run the linux folder in the terminal and run “ldd dfu-suffix” i get " not a dynamic executable"

looks like dfu-suffix is a 32-bit program, do you have 32-bit program support installed on your linux system?

i will check but i dont think i have.

it was a fresh install this evening.

it appears i don’t.
do you have a recommendation for this?

did a bit of digging around and found the answer to getting 32 bit to run.

in command you run

sudo dpkg --add-architecture i386


sudo apt-get update
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386

after that i was able to run the

ldd dfu-suffix

all i now well with the world once more!

thank you @profezzorn for showing me the way!
