Compiling and instaling Qt Creator from source error

[Kaluss]

Hello,
Im trying to install Qt Creator from source.

Qmake process is done without any problems, but when i do "make install INSTALL_ROOT=$INSTALL_DIRECTORY" I got those erros:

/home/qt-creator/src/shared/qbs/src/lib/corelib/api/projectdata.cpp: In member function ‘QStringList qbs::GroupData::allFilePaths() const’:
/home/qt-creator/src/shared/qbs/src/lib/corelib/api/projectdata.cpp:155: error: expected primary-expression before ‘[’ token
/home/qt-creator/src/shared/qbs/src/lib/corelib/api/projectdata.cpp:155: error: expected primary-expression before ‘]’ token
/home/qt-creator/src/shared/qbs/src/lib/corelib/api/projectdata.cpp:155: error: expected primary-expression before ‘const’
make[2]: *** [projectdata.o] Error 1
make[2]: Leaving directory `/home/qt-creator/qt-creator-build/src/shared/qbs/src/lib/corelib'

make[1]: Leaving directory `/home/qt-creator/qt-creator-build/src'
make: *** [sub-src-install_subtargets-ordered] Error 2

Does anybody know where is the problem?
