c++ - Adding SDL 1.2.15 Framework on XCODE 7: 2 times class main gives error at compilation -


this problem has been asked after extensive search on google i've found no questions related 1.2.15 version of sdl last version of xcode please allow me post problem (again) , solution i've found up-to-date version (30th september 2015).

config:

osx 10.10.5 xcode 7.0 sdl 1.2.15

how reproduce:

copied sdl.framework /library/frameworks explained on readme.txt

on xcode template > building settings > framework search path /library/frameworks

i included sdl framework on main.cpp file follows:

#include <sdl/sdl.h>

when try compile , test error because of double declaration of class main...

this error message:

undefined symbols architecture x86_64:   "_main", referenced from:      implicit entry/start main executable      (maybe meant: _sdl_main)

this how solved it:

i checked , saw sdl.h including following files:

#include "sdl_main.h" #include "sdl_stdinc.h" #include "sdl_audio.h" #include "sdl_cdrom.h" #include "sdl_cpuinfo.h" #include "sdl_endian.h" #include "sdl_error.h" #include "sdl_events.h" #include "sdl_loadso.h" #include "sdl_mutex.h" #include "sdl_rwops.h" #include "sdl_thread.h" #include "sdl_timer.h" #include "sdl_video.h" #include "sdl_version.h"  #include "begin_code.h"

one of them sdl_main.h , on file see:

#define main    sdl_main

this line producing conflict class main on main.cpp, commenting line on sdl_main.h or commenting line #include "sdl_main.h" on sdl.h solves issue. i'm noob on c++ (i learn @ university many years ago) other languages know "hacking" library bad practice... though seems particular compatibility problem maxosx , want use xcode...

please correct , comment, justify yes or no, i'm on learning process.

cheers!

i've resolved problem #undef main before declaration of main function.

html - Outlook 2010 Anchor (url/address/link) -

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
