c - Mac gcc trying to link against old, nonexistent library -

-

i'm writing simple c program uses taglib library. had installed library in /usr/local , compiled , linked program against it. i've since removed library , attempting link against compiled version of library in location. problem when compile program now, compiles cleanly, when attempting run it, program looking library used exist in /usr/local/lib instead of new location. example, code , new taglib library in /users/mdi/code/tag.

i'm compiling program this:

cc main.c -wall -i./taglib/bindings/c -o tag -l./taglib/bindings/c/.libs -ltag_c

like said, compile completes no errors or warnings. when attempting run binary, error:

dyld: library not loaded: /usr/local/lib/libtag_c.0.dylib referenced from: /users/mdi/code/tag/./tag reason: image not found trace/bpt trap

running 'otool -l' on binary shows this:

tag: /usr/local/lib/libtag_c.0.dylib (compatibility version 1.0.0, current version 1.0.0) /usr/lib/libsystem.b.dylib (compatibility version 1.0.0, current version 125.2.1)

why still trying use taglib library no longer exists in /usr/local/lib , more importantly, how fix this?

i don't develop on mac, believe problem library isn't located in default dynamic link path. varies on platform, /usr/local/lib common 1 amongst them, , that's why it's showing path linking @ runtime.

you can change default search path shard libraries, i'm uncertain of how on mac. should able set environment variable dyld_library_path within session force dyld search other directories before searching default directories.

%>  export dyld_library_path=/path/to/your/library:$dyld_library_path

adding directories default search path @ system level better environment variable solution above, i'm unaware of how on mac.

edit:

after little searching, found link you'll find helpful.

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

php - Replacing tags in braces, even nested tags, with regex -

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
