Undefined symbols for architecture i386: "_OBJC_CLASS_$...

[Joachim]

Hi,

In my iOS project I had CP 0.3 working.
Working on MacBookPro8,2 , osx 10.6.8 , XC 4.0.2

Since I upgraded to CPT 0.4 :
I updated al classes to CPT,
tried with different compilers,
cleaned and fresh builds,
linked flags are still in place : -ObjC -all_load

I get following messages :

I don't know what I'm missing here.
Can you help me in the right direction to solve this.

Tnx,

I think that's similar to the issue "Karl" was reporting in the
"Release 0.4 available" thread. See my suggestion about building the
lib vs using the binary there (assuming you were using the shipped
binary). That did the trick for me.

Were you using the SDK under 0.3? If so, that's no longer supported.
You need to switch over to the static library or dependent project
method.

Eric

[Joachim]

it's similar, but the solution is not mentioned.
For what i see.

[Joachim]

I removed the sdk with the move to CP 0.3 - static library

Now I deleted the header files and static library from my project
Added the new ones CPT 0.4.

[Joachim]

I still get those messages after the steps mentioned before.

Can anyone point me in a direction where to look how to solve this?

tnx,

Joachim

{Xcode 4}

Select your project in the Project Navigator and click on the target.
Check the "Link Binaries With Libraries" list on the "Build Phases"
tab. Make sure "libCorePlot-CocoaTouch.a" is in the list and is set to
"Required".

Eric

[Joachim]

Tnx,
but no success.

I'm working in Xcode 4,
libCorePlot-CocoaTouch.a is in the "Link Binaries With Libraries" with
the required tag.
and i also checked that it is 0.4 one ( created on 8 juli).

Still got the messages.

You need to make sure there is really no sdk still hiding somewhere. That will link otherwise.

I know I removed the sdk from my drive when I switched to the static
library with version 0.3.
And I will test tonight on a clean Lion install.
No sdk or whatever installed.
I will let you know

tnx

On the fresh Lion, I compile the project successfully.
No errors anymore.

Good that the errors are gone,
pity is that we still don't know why ( or I don't know )

thanks for all your help

Has anybody have solution on this problem ??

[Drew McCormack]

Did you include -ObjC and -all_load in your link flags?
