I recently downloaded qt to be able to create a GUI for my C++ program and was wondering how I can link the boost multi-precision library that I have downloaded to qt. In my .pro file, I've written:
However, this produces the errors: "can't map file, errno=22 file '/usr/local/lib/' for architecture x86_64" and "linker command failed with exit code 1 (use -v to see invocation)"
So it is saying that there is a problem. It says that the directory /usr/local/lib64/ , which you are trying to use, does not exist. So can you check that? Does that directory, in fact, not exist?
If it doesn't exist, do you understand that it's not possible to use things that don't exist?
