i am using in Qt Creator 3.5.1 (opensource) Based on Qt 5.5.1 (GCC 4.9.1 20140922 (Red Hat 4.9.1-10), 32 bit). the problem is while build the project controller pc the error occurred "is not a member of 'QSerialPort' connect(serial, &QSerialPort::errorOccurred, this . ^In Serialconnector.cpp .
kindly resolve it .
