Building Qtcreator 2.6 with qt5 alpha

[alizadeh91]

Hi,
I want to build QtCreator 2.6 with Qt5 alpha but i get many errors which all of them are same as brought below:
unknown replace function...

i've found the source of error in qtcreator.pri file :

defineReplace(cleanPath) {
    return($$clean_path($$1))
}

defineReplace(cleanPath) {
    return($$clean_path($$1))
}

To copy to clipboard, switch view to plain text mode 

Any suggestions?
