osx - OS X 10.6SDK compatible with 10.5 leopard system __ZNKSt13bad_exception4whatEV -


my project compiled 10.6sdk , selected 10.5 deployment target. when run binary in 10.5 leopard system gives me

symbol not found: __znkst13bad_exception4whatev

referenced from: ...... expected in: /usr/lib/libstdc++.6.dylib

sometimes ago got same problem , closed use boost header make solution temporary solution. why happen? if symbol not in 10.5 system, why compiles without problem?

i can't find library call symbol (probably boost where?)

edit:

i found guilty. thread.o compiled file call __znkst13bad_exception4whatev symbol. had updated boost library 1.46 1.53. before had same problem , had changed: 

#include <boost/thread.hpp>

to 

#include <boost/thread/thread.hpp>

and problem gone. when updated boost 1.53, calling again.

i compiled boost macports or b2. 

otool -l bin.v2/libs/thread/build/darwin-4.2.1/release/address-model-32_64/macosx-version-min-10.4/macosx-version-10.8/threading-multi/libboost_thread.dylib  bin.v2/libs/thread/build/darwin-4.2.1/release/address-model-32_64/macosx-version-min-10.4/macosx-version-10.8/threading-multi/libboost_thread.dylib:     libboost_thread.dylib (compatibility version 0.0.0, current version 0.0.0)     libboost_system.dylib (compatibility version 0.0.0, current version 0.0.0)     /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 56.0.0)     /usr/lib/libsystem.b.dylib (compatibility version 1.0.0, current version 169.3.0)

i still see /usr/lib/libstdc++.6.dylib. means doesn't compatible 10.5.

i looked solution static link libstdc++ cound't find it.

i still looking solution it.

edit2:

i think give up. don't have more time ridiculous situation. don't understand why apple don't supply updated libstdc++ 10.5 leopard system. there many problem libstdc++ in 10.5.

the main question why xcode did not tell me binary not compatible 10.5 system?

windows more backward compatibility. now, can compile xp sp3.

i use staticaly link in windows in apple imposible.

at moment have learnt if want use c++11 features, have compile 10.7 system. not 10.6 system too. in professional audio many people use still 10.6 system. have wait use c++11 because of apple's non static link situation or aplle's backward compatibility approach.

yes, little bit angry!

php - Why I am getting the Error "Commands out of sync; you can't run this command now" -

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

java - Are there any classes that implement javax.persistence.Parameter<T>? -

i'm using named queries fetch entities database using jpa , hibernate , came across puzzling me: how come there no default implementations of javax.persistence.parameter interface? i rather impressed how @staticmetamodel used criteriabuilder in jpa2 meaning type safety , don't have mess around setting string names. wanted apply similar of jpa1 ejb's i'm working on: dealergroup_.class: public dealergroup_ { public parameter<integer> id = new parameterimpl<integer>("id"); /// etc... } dealergroupfacade.class: // ... public dealergroup fetch(integer id) { typedquery<dealergroup> query = em.createnamedquery("dealergroup.fetchbyid", dealergroup.class); query.setparameter(dealergroup_.id, query); return query.getsingleresult(); } // ... i surprised find there no implementations of parameter interface - of course, implement myself absence makes me suspicious may mistake using in way? should implementing parameter...
