@JonB I can not understand, there is no ld folder.

@sude
In a terminal what does which ld report?

You just had to run that command and show its output.
Anyway if as @Christian-Ehrlicher says you don't have the necessary package installed then that is what you need to address.

sude

@JonB I installed but still there is an error.

@sude
In a terminal what does 'which ld' report?

Now the third request to execute this command...

JonB

@sude
After you have run the which ld and reported its output.

You have not said what OS you are running on, which would help for this question. Assuming you are Ubuntu or something which works similarly, please run this command:

locate --regex '/ld$'

and show us its output.

sude

@JonB I have rasbian but i can't see anyting about it as you can see.

Maybe a silly question, but did you install build essential package?

sudo apt install -y build-essential

sude

@KroMignon Yes i did :(

KroMignon

@sude Just to be sure to understand what's going wrong: do you using your RaspberryPI to build or do you build a PC?

Is Qt Creator running on RaspberryPI or on PC?

sude

@KroMignon It is rasbian and i am using raspberry pi 3 and i use qt creator in raspberry.

JonB

@sude
Since your RPi does not have the locate command I suggested earlier, now try:

find / -name ld -print 2>/dev/null

and show the output (better if you copy & paste the command run plus the output as text than show screen shots).

sude

@JonB

pi@raspberrypi:~ $ which ld
pi@raspberrypi:~ $ find / -name ld -print 2>/dev/null
/usr/bin/ld
/usr/lib/compat-ld/ld
/usr/lib/gold-ld/ld
/usr/share/doc/binutils/ld
pi@raspberrypi:~ $

My terminal output is like that.

JonB

@sude
OK, hold on, that is strange.

which ld shows no ld executable on your PATH.

But the find shows /usr/bin/ld. That should be both executable and on your PATH.

Output from ls -l /usr/bin/ld?
Output from echo $PATH?

sude

@JonB
pi@raspberrypi:~ $ ls -l /usr/bin/ld
toplam 0

It is zero how can i echo :(

JonB

@sude

pi@raspberrypi:~ $ ls -l /usr/bin/ld
toplam 0

I don't understand. The output should look something like mine under Ubuntu:

ls -l /usr/bin/ld
lrwxrwxrwx 1 root root 19 Oct 20 12:09 /usr/bin/ld -> x86_64-linux-gnu-ld

Since it's a soft link on mine and may be on yours, now try:

ls -lL /usr/bin/ld
-rwxr-xr-x 1 root root 1740384 Oct 20 12:09 /usr/bin/ld

on yours, please?

It is zero how can i echo :(

What is zero? On mine:

echo $PATH
/home/jon/.local/bin:/home/jon/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

JonB

@sude said in :-1: error: collect2: fatal error: cannot find 'ld':

pi@raspberrypi:~ $ ls -l /usr/bin/ld
toplam 0

Ah, hang on, that is indeed what you get if /usr/bin/ls is an (empty) directory:

mkdir empty
ls -l empty
total 0

Maybe toplam means total in your language?!

OK, that is indeed strange. /usr/bin/ld should be, or be a soft link to, an executable file, not a directory!

Go back to the find command. Assuming RPi find accepts -ls, try:

find / -name ld -ls 2>/dev/null

If not try:

ls -ld `find / -name ld -print 2>/dev/null`

Note those two ` ("backtick") characters, you will have to find that on your keyboard.

Well, again I don't understand/am surprised at your output.

Earlier your showed 4 matches for ld, including /usr/bin/ld. Now you show only 3 matches, not including /usr/bin/ld. I don't know why....

Last try:

ls -ld /usr/bin/ld ?
ls -lLd /usr/bin/ld?

Assuming those show it's a directory, or even that it does not exist, it does not look to me as though your RPi has ld installed/properly installed. Earlier you said sudo apt install -y build-essential was reporting "installed", but it doesn't feel right to me. Maybe you should try uninstall and reinstall, I don't know. I believe that until which ld returns an executable file path (e.g. /usr/bin/ld) you are in a bad state. But I know nothing about RPi....

sude

@JonB Thank you for your help but it cant be solved. :(

SGaist

Hi,

In that case you should maybe go with the nuclear option and restart from a clean installation on your RPi. As written by @JonB, if having installed build-essential does not give you all the tools, then there's likely something wrong with your system.

sude

@SGaist I tried it too but it didnt work. I dont know what i do wrong.
