gcc - Linking SDL2 and Clion -


i have clion pointing sdl2 directories , libs, fails link libraries when try build. ideas on how fix this?

cmakelists:

cmake_minimum_required(version 3.3)  project(cavestory_development)  set(cmake_c_flags "${cmake_c_flags} -wall -werror -lsdl2")  set(sdl2_include_dir c:/sdl2-2.0.3/i686-w64-mingw32/include/sdl2)  set(sdl2_library c:/sdl2-2.0.3/i686-w64-mingw32/lib)  find_package(sdl2 required)  include_directories(${sdl2_include_dir})  set(source_files main.cpp)  add_executable(cavestory_development ${source_files})  target_link_libraries(cavestory_development ${sdl2_library})

build errors:

"c:\program files (x86)\jetbrains\clion 1.1\bin\cmake\bin\cmake.exe" --build c:\users\conne_000\.clion11\system\cmake\generated\8a943732\8a943732\debug --target cavestory_development -- -j 8 [ 50%] linking cxx executable cavestory_development.exe cmakefiles\cavestory_development.dir/objects.a(main.cpp.obj): in function `sdl_main': c:/users/conne_000/documents/clionprojects/cavestory_development/main.cpp:11: undefined reference `sdl_init' c:/users/conne_000/documents/clionprojects/cavestory_development/main.cpp:21: undefined reference `sdl_createwindow' c:/users/conne_000/documents/clionprojects/cavestory_development/main.cpp:26: undefined reference `sdl_geterror' c:/users/conne_000/documents/clionprojects/cavestory_development/main.cpp:32: undefined reference `sdl_delay' c:/users/conne_000/documents/clionprojects/cavestory_development/main.cpp:35: undefined reference `sdl_destroywindow' c:/users/conne_000/documents/clionprojects/cavestory_development/main.cpp:38: undefined reference `sdl_quit' c:/mingw/bin/../lib/gcc/mingw32/4.8.1/../../../libmingw32.a(main.o):main.c:(.text.startup+0xa7): undefined reference `winmain@16' collect2.exe: error: ld returned 1 exit status mingw32-make.exe[3]: *** [cavestory_development.exe] error 1 cmakefiles\cavestory_development.dir\build.make:96: recipe target 'cavestory_development.exe' failed cmakefiles\makefile2:66: recipe target 'cmakefiles/cavestory_development.dir/all' failed mingw32-make.exe[2]: *** [cmakefiles/cavestory_development.dir/all] error 2 mingw32-make.exe[1]: *** [cmakefiles/cavestory_development.dir/rule] error 2 cmakefiles\makefile2:78: recipe target 'cmakefiles/cavestory_development.dir/rule' failed mingw32-make.exe: *** [cavestory_development] error 2 makefile:117: recipe target 'cavestory_development' failed

here minimal example started sdl2 on windows (main.cpp contains hello sdl lazyfoo)

cmake_minimum_required(version 3.0) project(hello_sdl2)  # configure sdl (cf.

tested on win8.1 64bits sdl2-2.0.3, mingw-w64 i686-5.2.0-posix-dwarf-rt_v4-rev0 , clion 1.2 eap (build 142.5239.6)

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...
