installing gcc 4.8, using recommended infrastructure libs reduce possible issues. built , installed gmp using default settings--> shared libs went /usr/local/lib built isl, make check cannot find installed gmp shared lib. installed isl anyway, shared libs went /usr/local/lib. built cloog, make check cannot find either installed isl or gmp shared libs so went cloog-0.18.0/.libs/ , made soft links /usr/local/lib/libisl.so.10.1.1 , libgmp.so.3 , re-ran make check without failures. these recommended infastructure tarballs downloaded gcc ftp server, , built , installed using default configuration. why might "make check" unable find shared libraries installed? should add: new ubuntu installation you need make sure /usr/local/lib in global shared library config -- check /etc/ld.so.conf -- /usr/local/lib should there or in 1 of files includes. if not, add , run ldconfig root rebuild cache.

i new nslayoutconstraint . i want manage content of nsscrollview programmatically. @ end, want create subclass of nsscrollview method - add:(nsview *)aview add aview after others , enlarge documentview of nsscrollview if necessary. (all osx) guess exists can't find it, if knows find this, in ;) here picture can understand : my plan use nslayoutconstraint s. constraints : equal vertical space between view 1 , view 2 , etc. the documentview height should adapt sum of heights of view 1 , view 2 , etc. some fixed vertical margins between documentview and view 1 , last view . view 1 , view 2 , etc. right-aligned so, let come question : have started adding view 1 (i see after rest). did following : thescrollview nsscrollview ; newsubview view want add ; respect picture, view 1 . thecontainer = [[nsview alloc] initwithframe:nsmakerect(0, 0, 0, 0)] ; [thescrollview setdocumentview:thecontainer] ; [newsubview settranslatesautoresizingmaskintoconstraints

how make parallel execution custom targets on $windows$, without using msvc? i have moderately results parallel job execution using cmake + jom , when compiling c++ targets. have targets, generate code. problem run on single core :( the cmake files quite complex now, in pseudo-code looks this add_custom_target(generate_all) foreach(domain ${domains}) add_custom_target(generate_${domain} command command-that-generates-domain-code ) add_dependencies(generate_all generate_${domain}) endforeach() when invoke jom generate_all , want dependant targets executed on cores. ok, solve problem, used ninja build system instead. because of visual studio strange compilation problems, compiled ninja under gentoo box (using mingw32-gcc toolchain). compiles without issues on win box, mingw . afterwards, can used on win box compile (c/cpp code, gnu/msvc compilers, + parallel job execution targets).

i want add spacing between end of legend entry , legend border. i've tried using arguments pyplot.legend haven't found combination works. here's minimal working example: import matplotlib.pyplot plt import numpy np x = np.linspace(0.0,1.0,10) y = x fig = plt.figure() p, = plt.plot(x,y,'-o') plt.legend([p],['$y = x$'], loc='best') plt.show() i've tried plt.legend([p],['$y = x\/$'], loc='best') plt.legend([p],['$y = x{ }$'], loc='best') plt.legend([p],['$y = x\:$'], loc='best') plt.legend([p],['$y = x$ '], loc='best') but none of them work. seems pyplot smart , removes trailing whitespace. there way accomplish this? to give example of why want this, it's balance out space on both sides using 1 marker instead of 2 in legend, see example below. space beside w-y , exp. smaller space on left. i think can want combination of kwargs borderpad , handletext

in existing app have activity inner class extends asynctask, looks following: public class activity_1 extends baseactivity { .... new async().execute(); ... public class asyncextends asynctask<void, void, string> { protected string doinbackground(void... progress) { ... } protected void onpreexecute() { ... } protected void onpostexecute(string result) { ... } } } now, need call same doinbackground-method activity, onpostexecute() of inner class operates on local ui variables , hence it's not possible use outside clas. there way can call asynctask, , override onpostexecute and onpreexecute -method, or shall create yet inner-class in other activity, same background thing (of course move common utility-class or something), etc...? you can make separate abstract package private class, extending asynctask , implementing doinbackground() method: abstract class myasynctask extends asynctask<void, void, string>

i have 2 values: x = -78.0921 , y = -64.6294 . now, when want compute math.pow(x, y) returns nan. should do? how can solve problem? how should calculate power? there other function can calculate this?...or maybe not defined mathematically ? you've tried compute number not real. by not real mean, if tried every single number between largest number , smallest number can think of, none of numbers solution -78.0921 power of -64.6294. in fact, no real number solution -1 power of 0.5, or square root of -1, , in general a^b if negative , b non-integer, the result not real. the inability express such useful result in real numbers lead invention of complex numbers. sqrt(-1) = i , imaginary unit, in complex number system - complex numbers have real component , imaginary component, expressed a + b*i . in general, no negative number fractional power produces real result, have component of in - closer .5 power is, more i, closer .0, more real, , path follows circle bet
