How do I fix this error?





It's very strange -- I compile a build for iOS, but get a error about Mac OS deployment target.

    You should link libz.dylib not any specific version. The correct version gets used automatically.

    Update the libz dylib version in your project definition to whatever your XCode 4.2 is providing. If you are compiling the same code for different targets, check the library version on each of them.

    Since SDK 3.2 all versions of libz are symbolic links to the last version (libz.1.2.3 in SDK 4.3), so regardless of what libz-version you choose, you get the last one. See /Developer/Platforms/iPhoneOS.platform/DeviceSupport/Latest/Symbols/usr/lib.

    I don't know what Apple will do in the future. If you link to libz you are likely to keep linking to the latest version. A change in the major number of the library (libz-X) could break compatibility, so a safer choice is to keep linking the same version you have now. Your choice.

    XCode 4.2 provides libz.1.2.5.dylib. You could link to that.

Why is this Javascript much *slower* than its jQuery equivalent?

By User
I have a HTML list of about 500 items and a "filter" box above it. I started by using jQuery to filter the list when I typed a letter (timing code added later): $('#filter').keyup( function() { var jqStart = (new Date).getTime(); var search = $(this).val().toLowerCase(); var $list = $('ul.ablist > li'); $list.each( function() { if ( $(this).text().toLowerCase().indexOf(search) === -1 ) $(this).hide(); else $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...

Is it possible to have IF statement in an Echo statement in PHP

By User
Thanks in advance. I did look at the other questions/answers that were similar and didn't find exactly what I was looking for. I'm trying to do this, am I on the right path? echo " <div id='tabs-".$match."'> <textarea id='".$match."' name='".$match."'>". if ($COLUMN_NAME === $match) { echo $FIELD_WITH_COLUMN_NAME; } else { } ."</textarea> <script type='text/javascript'> CKEDITOR.replace( '".$match."' ); </script> </div>"; I am getting the following error message in the browser: Parse error: syntax error, unexpected T_IF Please let me know if this is the right way to go about nesting an IF statement inside an echo. Thank you.
