Problems with Android 5 build on Mac OS X Yosemite: dyld: Symbol not found: _code_profile_dirname

[Summersmd]

I'm trying to build Android 5.0 on OS X Yosemite and am able to compile it with a bunch of warnings but when I try to run the emulator, I get the following error:

dyld: Symbol not found: _code_profile_dirname

  Referenced from: /Volumes/android/WORKING_DIRECTORY/prebuilts/android-emulator/darwin-x86_64/emulator64-arm

  Expected in: flat namespace

 in /Volumes/android/WORKING_DIRECTORY/prebuilts/android-emulator/darwin-x86_64/emulator64-arm

Trace/BPT trap: 5

I followed the instructions at http://source.android.com/source/building-running.html to configure my build environment and execute the build.

Any suggestions?

If you’re using Yosemite you’ve not followed all the instructions in that part of the website.

Could you please be more specific?  I'm struggling with this one.

I'm seeing the exact same thing. 

The offending symbol is in  external/qemu/code-profile.c

On master (and I haven't looked at the other 5.0.x branches) there was a Nov 5th commit (commit 16c74a05c0fec15cf21f7ca7524deb7f286ab540) to initialize code_profile_dirname but obviously this fix really didn't fix the emulator at all.

This isn't some sort of n00b build environment issue. FWIW I am on Yosemite for my build environment.

Tom

You need to read the documentation about setting up your environment to build Lollipop.

This is not an environmental issue as part of the Android build. 

emulator and friends which is being run and errors out with this problem is one of the prebuilt binaries. 

Hopefully will have some time to recreate this with a fresh qemu build sometime this weekend. As noted in my earlier post, there is supposedly a patch to address this from back in November and obviously it doesn't.

The fix is probably correct, but the emulator is not built when building on OS X. Instead, a prebuilt binary is used. The prebuilt binary currently on master was created before the fix, so it still has the issue. As a temporary workaround, I used the previous version, before the addition of the profiling support:

cd prebuilts/android-emulator

git checkout 3cc1518e492fae1b698f7be3e6311352bb8bcbec

Best regards,
