error when creating an archive of my cocos2d app

Question

I'm using cocos2d-iphone (develop-v2) and xcode 5 and have this error when trying to archive my app: (and not when I compile it)

libs/kazmath/src/neon_matrix_impl.c:64:15:

error: unknown register name 'q0' in asm
         : "memory", "q0", "q1", "q2", "q3", "q8", "q9", "q10", "q11", "q12", "q13", "q14", "q15" //clobber
                     ^
libs/kazmath/src/neon_matrix_impl.c:93:15: error: unknown register name 'q0' in asm
         : "memory", "q0", "q1", "q8", "q9", "q10", "q11" //clobber
                     ^
2 errors generated.

How to fix that?

I opened an issue here: http://code.google.com/p/cocos2d-iphone/issues/detail?id=1507&can=1&q=franck4321&colspec=ID%20Type%20Status%20Priority%20Milestone%20Component%20Owner%20Summary — franck, Oct 31 '13 at 07:08

I had to replace:

#if defined(__ARM_NEON__)

by:

#if defined(_ARM_ARCH_7)

in the file neon_matrix_impl.c.

update: maybe it's less clumsy to fix it in mat4.c and simply remove the ifdef and code that triggers the call to NEON_Matrix4Mul. in the kmMat4Multiply function – franck Apr 04 '14 at 12:44

You have to change ARM_NEON to ARMARCH_7 in two files , neon_matrix_impl.c and mat4.c . 64-bit should work fine after that. – suku Oct 17 '14 at 10:23

This is the error in kazmath if you just change in neon_matrix_impl.c only

Undefined symbols for architecture arm64:  
  "_NEON_Matrix4Mul", referenced from:  
      _kmMat4Multiply in libcocos2d-library.a(mat4.o)  
ld: symbol(s) not found for architecture arm64  
clang: error: linker command failed with exit code 1 (use -v to see invocation)

You have to change ARM_NEON to ARMARCH_7 in two files:

neon_matrix_impl.c
mat4.c

In both files search for the #if and replace it.

#if defined(__ARM_NEON__)

With

#if defined(_ARM_ARCH_7)

64-bit should work fine after that.

It would help if you formatted your answer so that the code had the proper line breaks. – Teepeemm Nov 12 '15 at 22:07
This helped fix my issue in trying to build my old game built with Cocos2d with 64 bit. – Paul Solt Mar 30 '20 at 14:41

#if defined(_ARM_ARCH_7) compiles with cocos2D v2.1, but does link errors (on iPad Air).

I've upgraded my karmath library with cocos2D v3 kazmath lib (https://github.com/cocos2d/cocos2d-iphone/tree/develop-v3/external/kazmath).

It works for me.
