아래 문제는 오염되었거나 손상된 소스코드였기 때문임

QtGui 없다고 에러나면

cc1: error: .pch/release-shared-emb-arm/QtGui: No such file or directory

make[1]: *** [.obj/release-shared-emb-arm/pixman-arm-neon-asm.o] Error 1

QtGui는 -no-pch로 회피가능하나... 근본적인 해결책은 아님

-no-pch

컴파일시 어셈블리 오류가 날 경우

(armv7-a로 했으나 armv5 계열로 뜬금없이 특정 어셈블리 명렁어를 인식할수 없다고 나는 경우)
