qt running error

[kyeo95]

Hi, I'm running Qt on Ubuntu Linux, but i'm having problem at running project I got in the github.

Project smoothly ran and built yesterday, but it suddenly crashed today.
I reinstall the Qt but didn't worked.

I have hundreds of error messages with out above error.

I don't think the project code is problem, I didn't touch it since yesterday when it executed well.
some thing got wrong in the system but I don't know what's the problem.
Any help would be very helpful! Thank you.

@kyeo95 What is the first error?
Did you try to delete the build folder, run qmake and build again?

@jsulm thank you for your reply.

I deleted build folder but result doesn't change. error messages still come out.

Are you able to build a simple C++ application using memcmp or one of the other mentioned method ?

No need to be concerned about number of errors, but

start from obvious : ( part of the first error screen shot )

"did you forget to #include .... ? "
