osx - How can I successfully link an assembly program on OS X? -


i learning assembly langauage, , reading book programming ground up. in first programming example

movl $1, %eax # movl $0, %ebx # int $0x80      #

i can assembly object file. when run ld exit.o exit, following error shows:

ld: warning: -macosx_version_min not specified, assuming 10.8 undefined symbols architecture x86_64:   "start", referenced from:      implicit entry/start main executable ld: symbol(s) not found inferred architecture x86_64

how can solve problem? running environment macos 10.9

the book you're reading assembly programming linux systems, not mac os x. while they're similar, they're not same, when comes low-level programming — if want follow directions in book, set linux virtual machine , use that.

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
