python - Library not loaded: QtCore.framework/Versions/4/QtCore -


i trying gui programming in python.i figured out pyside framework start with.as running python 2.7.2 downloaded pyside 2.7 , tried running sample app.i got qtcore library not loaded error.

this error got..

from pyside import qtcore, qtgui importerror: dlopen(/library/python/2.7/site-packages/pyside/qtcore.so, 2):  library not loaded: qtcore.framework/versions/4/qtcore referenced from: /library/python/2.7/site-packages/pyside/qtcore.so reason: image not found

i googled , found out many people facing same issue , saw solutions being posted based on exporting dyld_framework_path. not able follow this. please tell me whats issue , how fix it!! thanks..

you don't mention os working on, paths in error message looks you're on mac osx.

i'm not expert in pyside @ all, had same problem while ago , think know what's going on: library @ /library/python/2.7/site-packages/pyside/qtcore.so part makes qt core c++ library available python. wrapper though or sort of translator between c++ , python, actual c++ functionality elsewhere - , when python interpreter tries load c++ library contains functionality qtcore.framework/versions/4/qtcore, if fails find it, hence error message.

a quick , dirty way solve problem create symbolic links location qtcore.so expects c++ library is. that, have find c++ library. if downloaded qt 4.8.4 installer qt project page, libraries afaik somewhere in /usr/lib, create symlink this:

ln -vis /usr/lib/<insert subfolder>/qtcore.framework /library/python/2.7/site-packages/pyside/qtcore.framework

you have in similar way qtgui , other qt library want use well. note not symlink library itself, folder in qtcore.so expects it.

an alternate way build pyside sources (which ended doing), takes longer - , sound want going python , qt.

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
