iphone - Why is my app running -

-

i have compiled iphone app setting (device, release).

i install on test machine , runs no problem.

here's problem. app linked c++ library. compilation on simulator has no errors. device compilation produces 568 errors, different visibilities w.r.t appdelegate.o.

they like:

ql::error::~error()has different visibility (default) in /ql/build/release-iphoneos/libqllibrary.a(abcd.o) , (hidden) in /programming/objc/second/build/second.build/release-iphoneos/fg.build/objects-normal/armv6/appdelegate.o

why this, , how can stop errors anyway?

you can force visibility with: -fvisibility=hidden

(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."
