The attempt to build

[Banvok]

When you try to compile Qt Creator 4.8.7 message appears

./configure: / bin / sh ^ M: bad interpreter: No such file or directory

[ChrisW67]

What platform are you trying to configure/build it on?

Btw: There is no Qt Creator 4.8.7. Do you mean Qt 4.8.7 or Qt Creator 3.5.0?
