Getting this error "clang: error: linker command failed with exit code 1" in Robovm Studio?

[Steven Ferrarese]

I just imported my libgdx project that I have been working on in android studio on windows to robovm studio on my mac.  

I first got an error for not finding signing identity and fixed that.

I got this while trying to run the iOS part, it works fine on android. 

Any ideas on what is causing this error ?

This is the log read out,

Hi,

what libGDX version are you running? Please post your robovm.xml and the ios/build.gradle file. It appears that the linker tries to find the file /Users/stevof12/Documents/zomd/ios/build/libs/ios/libgdx-box2d.a. However, that mechanism has changed in libGDX a long time ago. If you are on a libGDX version from before this change, there should be a task in the ios/build.gradle file that copies the static libraries to the ios/build/libs/ios directory.

Best,

Mario

I have updated libGDX to latest version now and runs fine on IOS simulator, but when I go to generate an IPA i get this error ,

my IOS launcher java class is called IOSLauncher in the ios/scr/com.zombie directory.

[ERROR] Couldn't create IPA

Is there a way to post libgdx issues on libgdx forum ? 

[Mario Zechner]

Yes there is, at https://www.badlogicgames.com/forum

This looks like the classes have not been comiled by Gradle. Please make sure you compile the Java classes before you invoke the createIPA task. The libGDX wiki guides you through the process https://github.com/libgdx/libgdx/wiki/Gradle-on-the-Commandline#packaging-for-ios.
