Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Android Jelly Bean (4.1.2) log2 error


I'm facing an issue with UE4 (since 4.15) that is for an Android Device I have from Huawei (adreno GPU).

When I try to compile the android with matchndk and android-19, the compilation is successful, but in the runtime, appears this message:

 06-06 19:13:12.939: E/AndroidRuntime(10701): Caused by: java.lang.UnsatisfiedLinkError: Cannot load library: reloc_library[1306]:   304 cannot locate 'log2'...

If I compile with android-16 (or 17), the compiler fails with "no log2 function". Even if I create in my project header file an #define or even a function for 'double log2(double)', it fails with the message from another linked library (from UE4).

How can I solve this problem?

Thanks in advance.

Product Version: UE 4.16

Can I know if you've found any solution for this?

Not at all! I didn't test with new 4.17.0 Preview 2 engine version (yet). For now, I'm not using Android.

Thank you for your response. From 4.17.0, it is gone. I just tested it.

Just could test today. It is fixed, but I had to disable the Oculus Rift plugin from engine and change to android-16 build level for be able to compile and launch in the Android 4.1.2 device. Tested in UE4 4.17.1.

Hey, @SungLab, I don't know how this comments was split, I want to check your comment as answer corrected, but I can't. If you want to make a new answer with the fixes, I will mark it as correct. Thanks!
