library not found for -lstdc++ in Xcode - iphone

I am using the openCV2.framework in my application. It works fine in the simulator, but is not compiling for iOS devices. It get the following error
ld: library not found for -lstdc++
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I added other linking flag also...


Try using libc++ instead of stdc++. (lib)std++ went GPLv3, so Apple is pushing libc/c++ instead.


I am answer my own question. I solved this problem by add the go to Target -> BuildSettings ->search Path -> library Searchpath
give the correct path of added dynamic library Path .
Now it will work

Mac O Linker errors with Tesseract

I have a simple Swift iOS project created in Xcode 8.1 and added Tesseract Framework. I am getting
clang: error: -E or -x required when input is from standard input
There is no help on Google about this error. Can someone explain what this error means. I have -lstdc++ and -$(inherited) in my other linker flags. If I try to add -E flag it gives me a
Found an unexpected MAch-O header code: 0x20312023

Problem was wrong version of TesseractOCR.frmaework generated earlier (probably for simulator). Fixed it by regenerating the framework and replacing it in the project.

clang: error: linker command failed with exit code 1 (use -v to see invocation) Parse.com and Swift

so today I updated my code to Swift 2 and now my app won't run because apparently the Parse Frameworks I was using have expired or something. This is the message I get: ld:
'/Users/tripphillips1/Desktop/Spotter/Parse.framework/Parse(PFAnalytics.o)' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. for architecture arm64
Does anyone know what this means and how i can fix it?
Thanks

Ok so I found a solution to my problem. You have to go into the Build Settings and disable the Bitcode. Simple as that. Now it runs fine.

xcode7: hit linker command failed with exit code 1 under

I hit below error when build app on real device(ios9.0) use xcode7 beta:
ld: library not found for -lPods...... clang: error: linker command
failed with exit code 1 (use -v to see invocation)
I tried to
change the config "Enable Bitcode" to "NO".
hardcode Framework path under build setting tab
but it didn't help.

check this framework if existed in your project folder,you can right
click on this framework in Xcode.
if existed, delete this framework under Frameworks in Xcode and then copy this framework into Xcode again for re-reference.

ld: 871 duplicate symbols for architecture armv7, clang: error: linker command failed with exit code 1 (use -v to see invocation)

I am using FastPDFKit in my iPhone app for displaying PDF. When I run the project on simulator, it works fine. However when I run the project on iPhone, it gives me below error.
duplicate symbol _value_map in:
/Users/alkandari/Desktop/iPhone Apps/MyTest002/MyTest002/FastPdfKit.embeddedframework/FastPdfKit.framework/FastPdfKit(FastPdfKit)
duplicate symbol _writeUnicodeToUTF8Buffer in:

clang: error: linker command failed with exit code 1 (use -v to see invocation)
ld: 871 duplicate symbols for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Any idea why it is happening like this?
Error comes when I add FastPDFFramework in Configuration in Debug and Release section.

Here's a solution I found even after messing with the header/framework search paths, rebuilding, etc:
http://support.fastpdfkit.com/discussions/problems/443-i-am-unable-to-link-fastpdfkitembeddedframework
I removed the -all_load linker flag in my project and it compiled successfully. As a warning, make sure removing this flag is appropriate for your project. It was probably placed there for a reason

Can you try to clean up the FastPdfKit target and recompile it? It should generate a new framework ex-novo that you then should be able to add to you project, overwriting the one you are using. You can grab the new .embeddedframework in the FastPdfKit project root directory.
These line helped me from the link below.
http://support.fastpdfkit.com/discussions/problems/759-duplicate-symbols-for-architecture-armv7

there are another reason this error often happens is accidentally importing the .m file instead of the .h.
it's happened to me :)

You have too many #include or #import directives in header files for the same things. Move to using #class in headers and only import/include in your .m files.
In all you just need to review where these are and reassess them.

I add my solution, as if you follow the readme, it will ask you to do:
Inherit the project options: select the Project an from info tab and configurations line choose **FastPdfKitFramework** from the drop down list;
I replace the FastPdfKitFramework target to None and now it work great.
As it is on the readme file, I never add .a in my project so download the recompile one don't help me as I do not want to restart all integration.
I hope it can be helpful for someone.

I tries removing -all_loads linker flag, and it worked for me without any problem in the project.

libsqlite3.0.dylib not found when build in a iPhone

I trie to put my application in a physic iPhone but xCode tell me that the library libsqlite3.0.dylib is not found.
Error code :
ld: library not found for -lsqlite3.0

I can't use libsqlite3.dylib because I deleted it by misteak and I don't find a download link.
The application work perfectly on the IOS Simulator.
Thanks for your help !!
EDIT !
I reinstalled xCode and use the sqlite3.dylib framework and work perfectly !
