c++ - Can't build PortAudio for i386 to make it play nice with NI's DAQmxBase -


i'm trying write little c/c++ program both acquires data ni usb daq , plays audio portaudio. problem is, appears ni daq library mac/linux, daqmxbase, has built under i386, , can't portaudio build i386.

i have tried setting cflags , ldflags -arch=i386 before running ./configure --disable-mac-universal && make && make install, ni daqmxbase example code still won't build when add calls portaudio it: 

gcc -i../../includes -g -o2 -arch i386 acanalogtest.c -framework nidaqmxbase -framework nidaqmxbaselv -o acanalogtest   undefined symbols architecture i386:       "_pa_initialize", referenced from:           _main in ccf1t0bz.o     ld: symbol(s) not found architecture i386     collect2: ld returned 1 exit status     make: *** [acanalogtest] error 1

the ni daqmxbase makefile looks this:

nilibs=-framework nidaqmxbase -framework nidaqmxbaselv                                                               includes=-i../../includes flags= -g -o2 -arch i386 cc=gcc  ao_examples = acanalogtest acquirenscans ...... : $(ao_examples)  % : %.c  >---$(cc) $(includes) $(flags) $< $(nilibs) -o $@  clean : >---rm -f $(ao_examples)

changing -arch flag in daqmxbase makefile doesn't work:

gcc -i../../includes -g -o2 -arch x86_64 acanalogtest.c -framework nidaqmxbase -framework nidaqmxbaselv -o acanalogtest in file included acanalogtest.c:1: ../../includes/nidaqmxbase.h:104: warning: division 0 ../../includes/nidaqmxbase.h:104: error: enumerator value ‘assert_line_104’ not integer constant ../../includes/nidaqmxbase.h:105: warning: division 0 ../../includes/nidaqmxbase.h:105: error: enumerator value ‘assert_line_105’ not integer constant make: *** [acanalogtest] error 1

i assume because daqmxbase written i386 data types in mind. lines above error references nidaqmxbase.h are:

nistaticassert(sizeof(long) == 4, "error: platform unsupported because long not 4 bytes.");               nistaticassert(sizeof(int) == sizeof(long), "error: platform unsupported because int not same size long.");

i can build of normal portaudio examples on own fine, want put portaudio , daqmxbase in same program , have them along. there must way build portaudio works daqmxbase, no?

thanks!

daqmx base versions 14.0 , 15.0 support 64-bit applications, should able upgrade driver , try again.

daqmx base 15.0 mac

html - Sizing a high-res image (~8MB) to display entirely in a small div (circular, diameter 100px) -

first of all, thank being patient know simple question more couple of weeks' experience figure out. i've seen folks persevere , helpful on here , hope you're willing me. here fiddle: http://jsfiddle.net/65uzf/ here 1 of places searched answers on here: ( vertically center image thumbnails fix-sized div ) tried solutions on there , didn't work out me. i've searched ~4 or 5 others, , been unsuccessful those, too. what want take large image (what linked background-image #ysypic , #tabpic divs) , display thumbnail version of image in confines of divs have set it. is, using background properties have laid out in css, portion of image displays inside of circular divs. without these properties, display defaults smaller section of image [presumably pi*(50^2) area in top left] terrible resolution. i not care if entire image doesn't display inside of circles (it won't, given difference in shape), , overflow not being displayed fine. want able see figu

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
