Buck: Buck does not support Android NDK r11b ("Failed to read version")

[bmihai]

When running a buck clean I get the message BUILD FAILED: Failed to read NDK version from followed by the actual path to the NDK. This doesn't happen with r10e or r10d, only with r11b.

There's also the year-old issue #306 bug that cripples Android NDK r10e too.

help me
When running a " buck build :conceal_android" i get message is "BUILD FAILED: Failed to read NDK version from /home/Android/Sdk/ndk-bundle"
how do?

[bmihai]

Just wanted to add that this is still happening with the Android NDK r11c, released just recently.

Same issue here

[flopex]

It seems that buck depends on the file RELEASE.TXT to exist under the ANDROID_NDK path. See https://github.com/facebook/buck/blob/master/src/com/facebook/buck/android/DefaultAndroidDirectoryResolver.java#L125

To "fix" this just add the file RELEASE.TXT to the ANDROID_NDK path with the following contents

Example: /opt/android-ndk-r11c/RELEASE.TXT

r11c (64-bit)

[winterDroid]

Yes I know. But it seems Buck is not compatible with r11c because of another issue:

Reason for it is that the path does not exist. It is version 4.9 and not 4.8

[flopex]

@winterDroid I worked around that by ln -s arm-linux-androideabi-4.9 arm-linux-androideabi-4.8 as I couldn't find where it specifies to use 4.8

[flopex]

@winterDroid Actually the built in way of specifying the gcc-version is through the .buckconfig file in the project

[ndk]
    gcc_version = 4.9

The default is in https://github.com/facebook/buck/blob/master/src/com/facebook/buck/android/NdkCxxPlatforms.java#L81

[vigilancer]

@flopex, thanks
[ndk] thingy works for project build, but to install buck one still need to make ln -s.

[Coneko]

This should have been fixed by 7a6fba112f62abf865c27e3dd91d6e5d97625d95.

@vigilancer What do you mean? Does buck install not read the ndk.gcc_version? It should.

[vigilancer]

@Coneko, I ment installing Buck afresh with brew install.
Maybe there is a way to specify gcc_version at install time I'm not aware of.

[Coneko]

@vigilancer I have not been able to reproduce that. If you still have this problem can you open a new issue with instructions on how to reproduce it?

[bmihai]

For some reason the original bug is still up for me. I now get this error message when running a buck clean:

BUILD FAILED: could not extract version from NDK repository at com.facebook.buck.io.ProjectFilesystem@470a90de (projectRoot=/home/mihai/bin/android-ndk-r11c, whiteListedPaths=Optional.absent(), blackListedPaths=[]: /home/mihai/bin/android-ndk-r11c/RELEASE.TXT

I'm on buck commit 1d1d4a4. The source.properties file exists and is readable. It contains the text

Pkg.Desc = Android NDK Pkg.Revision = 11.2.2725575

[Coneko]

Can you run buck kill to make sure the daemon restarts, then try again?

[vigilancer]

@Coneko
I suppose my problem relate to this issue.
If you do not agree I'll move description to new issue.
Until than, here it is:

$brew uninstall buck
$brew update && brew upgrade --all

Workaround is to create and edit RELEASE.TXT and ln -s arm-linux-androideabi-4.9 arm-linux-androideabi-4.8 as @flopex suggested.

[sdwilsh]

v2016.03.28.01 is not going to have the fix, FWIW. I think @ryu2 is
working on getting the most recent release out to homebrew.

[bmihai]

@Coneko, I've tried doing a buck kill first and no changes, same error message. I've tried it with the lastest commit, 797cdf6.

[Coneko]

@bmihai What does buck --version say?

[bmihai]

It also gives the same error message:

BUILD FAILED: could not extract version from NDK repository at com.facebook.buck.io.ProjectFilesystem@470a90de (projectRoot=/home/mihai/bin/android-ndk-r11c, whiteListedPaths=Optional.absent(), blackListedPaths=[]: /home/mihai/bin/android-ndk-r11c/RELEASE.TXT

If I change the project's local.properties to use android-ndk-r10d (the last fully working version) it says:

buck version 797cdf60b1f26acd59bbe2b34340089107785532
