duplicate symbol _GAD_MD5

[Andrew_I]

I have following linking error during build my project with AdMob iOS 6.4.0 SDK.

duplicate symbol _GAD_MD5 in:

    ../Admob/libGoogleAdMobAds.a(md5.o)

    ../Admob/libGoogleAdMobAds.a(gad_md5.o)

ld: 1 duplicate symbol for architecture armv7s

clang: error: linker command failed with exit code 1 (use -v to see invocation)

It looks like problem in libGoogleAdMobAds.a library.

Are you using the -all_load flag for some reason? If you are, you should probably change it to use -force_load and point it to whatever SDK requires it.

I have changed linker flag to -force_load. Result is same.

duplicate symbol _GAD_MD5 in:

    ../Admob/libGoogleAdMobAds.a(md5.o)

    ../Admob/libGoogleAdMobAds.a(gad_md5.o)

ld: 1 duplicate symbol for architecture armv7s

Please see the issue more careful. The problem is in the libGoogleAdMobAds.a and it looks like two object files (md5.o, gad_md5.o) inside this library are exporting one symbol with same name (_GAD_MD5). This issue is only for armv7s architecture, build with armv7 working good (with -all_load and -force_load options).

What path did you give the -force_load flag? We've seen this issue come up when you do -force_load or -all_load for the admob SDK (which you shouldn't need to do with the latest SDK).

What other SDK's are you using? If you're using any that require the -all_load flag, you should replace them with -force_load followed by the path of the SDK that requires it.

What SDK's are you using that require the -all_load flag? Are you sure you've used -force_load with the correct path for all of them.

If you want, you can send me a small test app with the SDK's you're using linked and I can see if I can get the linker flags to work right.

Are you saying that you've tried the -force_load flag (http://developer.apple.com/library/mac/#qa/qa1490/_index.html) and pointed it at ShareKit's static library but you're still getting the error? Can you send me a small sample project with the error happening with you trying -force_load?

Sharekit (available on GitHub) requires this, for instance. It provides an implementation of various social media sharing (Facebook, Twitter, G+...).

Yes, same here

it seems i solved it. 

If you're using the Admob v6.2 library make sure you're NOT using the -all_load linker flag, use the-ObjC linker flag instead, apart from -Obj-C
