c++ - error: no match for ‘operator=’ -

i trying compile source in repository:

https://github.com/maartenbaert/ssr

and compilation errors on particular source file:

https://github.com/maartenbaert/ssr/blob/master/src/gui/pageoutput.cpp

with following error:

../../src/gui/pageoutput.cpp:66: error: no match ‘operator=’ in ‘((pageoutput*)this)->pageoutput::m_containers = {{"matroska (mkv)", "matroska", {"mkv"}, "matroska files (*.mkv)", {(pageoutput::enum_video_codec)0u, (pageoutput::enum_video_codec)1u, (pageoutput::enum_video_codec)2u}, {(pageoutput::enum_audio_codec)0u, (pageoutput::enum_audio_codec)1u, (pageoutput::enum_audio_codec)2u, (pageoutput::enum_audio_codec)3u}}, {"mp4", "mp4", {"mp4"}, "mp4 files (*.mp4)", {(pageoutput::enum_video_codec)0u}, {(pageoutput::enum_audio_codec)0u, (pageoutput::enum_audio_codec)1u, (pageoutput::enum_audio_codec)2u}}, {"webm", "webm", {"webm"}, "webm files (*.webm)", {(pageoutput::enum_video_codec)1u}, {(pageoutput::enum_audio_codec)0u}}, {"ogg", "ogg", {"ogg"}, "ogg files (*.ogg)", {(pageoutput::enum_video_codec)2u}, {(pageoutput::enum_audio_codec)0u}}, {"other...", "", <brace-enclosed initializer list>(), "", <brace-enclosed initializer list>(), <brace-enclosed initializer list>()}}’ /usr/lib/gcc/x86_64-redhat-linux6e/4.4.6/../../../../include/c++/4.4.6/bits/vector.tcc:156: note: candidates are: std::vector<_tp, _alloc>& std::vector<_tp, _alloc>::operator=(const std::vector<_tp, _alloc>&) [with _tp = pageoutput::containerdata, _alloc = std::allocator<pageoutput::containerdata>] /usr/lib/gcc/x86_64-redhat-linux6e/4.4.6/../../../../include/c++/4.4.6/bits/stl_vector.h:336: note:                 std::vector<_tp, _alloc>& std::vector<_tp, _alloc>::operator=(std::vector<_tp, _alloc>&&) [with _tp = pageoutput::containerdata, _alloc = std::allocator<pageoutput::containerdata>] /usr/lib/gcc/x86_64-redhat-linux6e/4.4.6/../../../../include/c++/4.4.6/bits/stl_vector.h:356: note:                 std::vector<_tp, _alloc>& std::vector<_tp, _alloc>::operator=(std::initializer_list<_tp>) [with _tp = pageoutput::containerdata, _alloc = std::allocator<pageoutput::containerdata>] make[2]: *** [simplescreenrecorder-pageoutput.o] error 1

the offending code, formatted:

m_containers = {         {"matroska (mkv)", "matroska", {"mkv"}, "matroska files (*.mkv)",                 {video_codec_h264, video_codec_vp8, video_codec_theora},                 {audio_codec_vorbis, audio_codec_mp3, audio_codec_aac, audio_codec_uncompressed}},         {"mp4", "mp4", {"mp4"}, "mp4 files (*.mp4)"     ,                 {video_codec_h264},                 {audio_codec_vorbis, audio_codec_mp3, audio_codec_aac}},         {"webm", "webm", {"webm"}, "webm files (*.webm)"   ,                 {video_codec_vp8},                 {audio_codec_vorbis,}},         {"ogg", "ogg", {"ogg"}, "ogg files (*.ogg)"     ,                 {video_codec_theora},                 {audio_codec_vorbis}},         {"other...", "", {}, "", {}, {}}, };

i'm more of c programmer , c++ bit rusty. have searched around , error common have yet been unable figure out problem one.

gcc 4.4.6 doesn't support having std::initializer_list parameter, list assignment isn't possible. however, it's easy work around if upgrading gcc not possible:

pageoutput::containerdata temp[] = {         {"matroska (mkv)", "matroska", {"mkv"}, "matroska files (*.mkv)",                 {video_codec_h264, video_codec_vp8, video_codec_theora},                 {audio_codec_vorbis, audio_codec_mp3, audio_codec_aac, audio_codec_uncompressed}},         {"mp4", "mp4", {"mp4"}, "mp4 files (*.mp4)"     ,                 {video_codec_h264},                 {audio_codec_vorbis, audio_codec_mp3, audio_codec_aac}},         {"webm", "webm", {"webm"}, "webm files (*.webm)"   ,                 {video_codec_vp8},                 {audio_codec_vorbis,}},         {"ogg", "ogg", {"ogg"}, "ogg files (*.ogg)"     ,                 {video_codec_theora},                 {audio_codec_vorbis}},         {"other...", "", {}, "", {}, {}}, };  m_containers.assign(std::begin(temp), std::end(temp));

i can't remember if std::begin/end exist in version, they're trivial implement otherwise:

template<typename t, std::size_t n> t *begin(const t(&arr)[n]) {return arr;}  template<typename t, std::size_t n> t *end(const t(&arr)[n]) {return arr + n;}

plot - Remove Objects from Legend When You Have Also Used Fit, Matlab -

Image
i've plotted data points , fitted exponential curve between them using 'fit' in matlab. problem fit-function got fitted line wanted plot, markers on top of regular markers. solved problem plotting wanted markers on top of unwanted couldn't seen. problem. when want show legends dots in there. how can remove markers legend without removing fitted line since both of them hidden inside fit-function? can stop 'fit' plotting unwanted markers? so, want remove blue dot called 'hoff' in picture below. you can leave out legend-entries manually leaving out handles of lines, dont want in legend. try this: %if plot something, want showing in legend, save handle: h_line = plot(x,y) %you dont want show line? dont anything, plot it: plot(mymarker) %then set legend-> can add text legend-entries %a cell-array containing strings want show up: legend([h_line another_line],{'text1' 'text2'}) with example (see comments) came solution:

java - Why does my date parsing return a weird date? -

-
here code using: string string = "08/07/2013".replace('/', '-'); date date = new simpledateformat("yyyy-mm-dd").parse(string); why date return: "wen jan 3 00:00:00 est 14"? not @ date format told use. edit: need format because database using requires format. the format use parse date string, not match it. using yyyy 08 . use following format: new simpledateformat("dd-mm-yyyy") and why @ replacing / - ? can build pattern original string only: string string = "08/07/2013" date date = new simpledateformat("dd/mm/yyyy").parse(string); and if want date string in yyyy-mm-dd format, can format date using dateformat#format(date) method: string formatteddate = new simpledateformat("yyyy-mm-dd").format(date); see also: change date format in java string simpledateformat java doc
