[INSTALL]
X264 Library

./configure --prefix=/home/sunsson/work/lib --includedir=/home/sunsson/work/include --libdir=/home/sunsson/work/lib --enable-shared => make => make install (root) 

가끔씩 isfinite() 때문에 컴파일이 안 되는 경우(sun-i386)가 있다.
이럴 경우에는 encoder/ratecontrol.c에 다음 MACRO를 정의한다.

// isfinite() comes with C99; fake version here in case compiler lacks it.
#ifndef isfinite
#define isfinite(x) (sizeof(x) == sizeof(float) ? isfinitef(x) : isfinited(x))
#define isfinitef(x) ((x) >= -FLT_MAX && (x) <= FLT_MAX)        // NAN should fail this, yes?
#define isfinited(x) ((x) >= -DBL_MAX && (x) <= DBL_MAX)
#endif // not isfinite
