I can't post them all but they all look like the ones above
xwolf9100 (13)
I read both of those and still don't understand how to solve this problem
xwolf9100 (13)
bump~

This kind of error is often caused by a mismatch of settings. I. e. you compiled your project with multi threading but not the library.
xwolf9100 (13)
So what should I do?
xwolf9100 (13)
Anyone?
coder777 (8444)
Look into the settings of each project. Especially 'Character Set' and 'run time libraries' should be the same.

Plus look at the docs of the libraries whether they need special preprocessor definition
