Might be a silly question but did you execute that command in the folder where qwt.framework is located ?

[thippu]

@SGaist Thanks for asking this question, I did not know that I should execute that command in the folder but I know qwt installation path and how to locate the qwt.framework path?

[thippu]

@SGaist
Did execute on this path /user/lib/
qwt.framework is there here.
output of the command is below:

qwt.framework was in otool -L qwt.framework/qwt
qwt.framework/qwt:

@thippu Still has the issue, what to do?

[SGaist]

otool won't automatically correct anything. In this case it was to look at the dependencies and the id of the framework.

Use install_name_tool and change the id to contain the full path.

[thippu]

@SGaist
Like this? :

install_name_tool /user/lib/qwt

[SGaist]

Did you read the help of that command ?

[thippu]

@SGaist Yes, I did try like this :

install_name_tool -help

output of the command:

Usage: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/install_name_tool [-change old new] ... [-rpath old new] ... [-add_rpath new] ... [-delete_rpath old] ... [-id name] input

I did like this also

install_name_tool -id /Users/axx/lib/qwt.framework/qwt.framework/Versions/6/qwt

the output of the command has no change why?

Usage: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/install_name_tool [-change old new] ... [-rpath old new] ... [-add_rpath new] ... [-delete_rpath old] ... [-id name] input```

@thippu said in Library not loaded: qwt.framework/Versions/6/qwt:

[-id name] input

Where is the "input"?

[thippu]

@jsulm install_name_tool -id /Users/lib/qwt.framework/qwt.framework/Versions/6/qwt
after the

-id 

The path is input right?

[jsulm]

@thippu I don't know, I'm not an MacOS expert. @SGaist probably knows.

[thippu]

@jsulm Thanks for the reply.

[thippu]

@thippu you are right I was missing the input keyword,
now if I do this

install_name_tool -id input /Users/lib/qwt.framework

output is : can't map file qwt.framework(invalid argument)

[SGaist]

install_name_tool -id /Users/axx/lib/qwt.framework/qwt.framework/Versions/6/qwt /Users/axx/lib/qwt.framework/qwt.framework/qwt

[edit: Fixed path SGaist]

[SGaist]

What version of Xcode are you using ?

[thippu]

@thippu
I did try to create a soft link by doing this:

sudo ln -s /usr/local/qwt-6.1.3/lib/qwt.framework/qwt /usr/lib/qwt

output:

ln: /usr/lib/qwt: Operation not permitted

[thippu]

What about this link solution:http://macappstore.org/qwt/

Press Command+Space and type Terminal and press enter/return key.
Run in Terminal app:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" < /dev/null 2> /dev/null
and press enter/return key. 
If the screen prompts you to enter a password, please enter your Mac's user password to continue. When you type the password, it won't be displayed on screen, but the system would accept it. So just type your password and press ENTER/RETURN key. Then wait for the command to finish.
Run:
brew install qwt
