I'm running qwt-6.1-multiaxes with Qt5.14.2 and I'm getting the following error, I've tried many ways to solve it, I hope someone can help me.

Hi and welcome to devnet,

How are you building it ?
Where did you put the libraries ?

@SGaist Hi,
Firstly, Qwt-6.4.0-svn is compiled from Qwt-6.1-multiaxes.

To build Qwt-6.4.0-svn, I followed these steps:

I used the qmake command with the qwt.pro file to generate the necessary build files.
Then, I ran the make command to compile the source code.
After that, I used sudo make install to install the Qwt library.
As for the library placement, I placed the Qwt-6.4.0-svn files in the following path: /usr/local/.

To check if the library is properly linked, I used the ls command.

I have previously used Qwt versions 6.1.2 and 6.2.0 successfully. However, in this case, I needed to use Qwt-6.1-multiaxes because it was used by the previous developer. Unfortunately, I'm facing issues with linking Qwt-6.1-multiaxes, and the problem keeps persisting.
Thanks

Use otool on your binary to check where it is looking for for that library.

Hi,I'm sorry I don't particularly understand which binary you are referring to. If it's "qmake" and "make", then it's in "/Users/XXXXXX/Qt5.14.2/5.14.2/clang_64/bin/ ".
Thanks for your reply

Run it on the binary of your application.
