how to enable process control extension (PCNTL) in PHP MAMP? -

-


have mamp , need enable -pcntl on current mamp installation. how can so?

thanks help.

there way of compiling pcntl extension , linking in existing php build, it's bit in-depth.

i'm doing following on mac osx snow leopard (64bit), mamp , php version 5.3.6. remember change php version numbers in following lines if yours different!

please note make required, isn't installed default on mac osx. need install via mac developer tools, http://developer.apple.com/unix/

first, download tar of php source code matches version using in mamp (e.g. mine 5.3.6), can @ http://www.php.net/releases/. untar , cd php-[version]/ext/pcntl, e.g.:

$ wget http://museum.php.net/php5/php-5.3.6.tar.gz $ tar xvf php-5.3.6.tar.gz $ cd php-5.3.6/ext/pcntl

you need run phpize in pcntl directory, binary file comes mamp:

pcntl$ /applications/mamp/bin/php/php5.3.6/bin/phpize

this creates bunch of files needed preparing extension compiling.

we need add flags tell compile library dual 32bit , 64bit architecture, mamp php has been built way. if don't this, compiled shared objects won't work.

pcntl$ macosx_deployment_target=10.6 pcntl$ cflags="-arch i386 -arch x86_64 -g -os -pipe -no-cpp-precomp" pcntl$ ccflags="-arch i386 -arch x86_64 -g -os -pipe" pcntl$ cxxflags="-arch i386 -arch x86_64 -g -os -pipe" pcntl$ ldflags="-arch i386 -arch x86_64 -bind_at_load" pcntl$ export cflags cxxflags ldflags ccflags macosx_deployment_target

we can run ./configure , make build our shared object:

pcntl$ ./configure pcntl$ make

this puts file called pcntl.so in modules directory. copy file mamp's php extensions directory:

pcntl$ cp modules/pcntl.so /applications/mamp/bin/php/php5.3.6/lib/php/extensions/no-debug-non-zts-20090626/

finally, edit php ini file include extension:

$ echo "extension=pcntl.so" >> /applications/mamp/bin/php/php5.3.6/conf/php.ini

pcntl should enabled. check see whether has been added, run:

$ /applications/mamp/bin/php/php5.3.6/bin/php --ri pcntl  pcntl  pcntl support => enabled

if see that, it's worked! if has gone wrong can remove pcntl.so file mamp php extensions directory , remove ini setting, , try again.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

android - layout with fragment and framelayout replaced by another fragment and framelayout -

edit: so after comments below, revisted , realized hanging me up. imagine client list , client details activity started : public class clientsmainactivity extends fragmentactivity { @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); //studiotabopenhelper db; setcontentview(r.layout.main_client_activity); } } so works great, starts main_client_activity (defined in layout below, , call activity when button on main screen clicked): intent intent = new intent(getactivity(), clientsmainactivity.class); startactivity(intent); easy issue is, clientsmainactivity not call oncreateview or anything, sets layout layout defines fragment, , listfragment. fine cause not trying pass clientsmainactivity , if have hypothetical activity like: sessionmainsactivity called when click on session edit of client, not calling sessionsmainactivity same way (starts activity sets alayout), want layout set defines...
