Hello everyone:
When I use ccpentium compiler to build a qvector class, it appears the following error:
../../include/QtCore/../../src/corelib/tools/qvector.h:569: error: unable to find a register to spill in class 'FLOAT_REGS'
Could anyone give me some solutions or suggestions about that? The full compiler outout and error as the following:
