ERROR:root:code for hash md5 was not found.

Hello,

I'm trying to build Skia for android, but unfortunately I'm stuck with the following issue:

[jenkins@jenkins skia]$ ./platform_tools/android/bin/android_ninja -d x86
ANDROID_HOME not set so we are setting it to a default value of ANDROID_SDK_ROOT

Building this on a Centos 7.2 machine.

I installed the relative python dev package and all kinds of SSL related packages.

I got to the point where importing the  hashlib  on python on the host machine  works.

But from the looks of things skia downloads its own copy of python which has difficulty finding the necessary crypto libraries.

That's unusual, but probably expected.  I bet we've never tried building Skia, to say nothing of the weird bits we do for Android, from a Centos machine.

Can you build Skia for your machine correctly?  E.g. does $ ./gyp_skia && ninja -C out/Release work for you?

Skia folks, is it expected that ./gyp_skia uses the NDK distributed Python when run via android_ninja?  That seems unusual.

  File "/opt/skia/skia/third_party/externals/gyp/pylib/gyp/generator/ninja.py", line 2415, in GenerateOutput
    pool.map(CallGenerateOutputForConfig, arglists)
  File "/opt/skia/skia/platform_tools/android/toolchains/x86-r12b-14/lib/python2.7/multiprocessing/pool.py", line 250, in map
    return self.map_async(func, iterable, chunksize).get()

This bit may be bypassable if we can get --no-parallel passed through to GYP.  GYP will only try to use the multiprocessing module if the default 'parallel' parameter is active.

Works like a charm:

[jenkins@jenkins skia]$ ./gyp_skia && ninja -C out/Release
GYP_GENERATORS environment variable not set, using default, ninja
ninja: Entering directory `out/Release'

[Derek Sollenberger]

I wasn't aware that android_ninja caused us to use a different python.  I don't see any code in our android scripts that points to a different python library.  Could it be that GYP is trying to do something clever behind our backs when we set GYP_GENERATORS=ninja-android?

Looks like some library references aren't resolved.

[root@jenkins skia]# find ./ -iname "*.so" -exec ldd {} \;

libc.so => not found

libm.so => not found

liblog.so => not found

libdl.so => not found

./platform_tools/android/toolchains/x86-r12b-14/host_prebuilt/lib/python2.7/lib-dynload/_hashlib.so: /lib64/libcrypto.so.1.0.0: version `OPENSSL_1.0.0' not found (required by ./platform_tools/android/toolchains/x86-r12b-14/host_prebuilt/lib/python2.7/lib-dynload/_hashlib.so)

[Mike Klein]

Does anyone else reading this have a Centos machine?  If not, I'm not sure we can help you.  Almost all our Linux-based development is done on Ubuntu.

[Christophe Vanlancker]

I think I just made a breakthrough.

I installed an older package of libopenssl1_0_0  (libopenssl1_0_0-1.0.1k-11.87.1.x86_64.rpm)  meant  for OpenSuse  and it works.

[jenkins@jenkins skia]$ ./platform_tools/android/bin/android_ninja -d x86

ANDROID_HOME not set so we are setting it to a default value of ANDROID_SDK_ROOT

ninja: Entering directory `/opt/skia/skia/out/config/android-x86/Release_Developer'

I feel terribly dirty though, it seems to have fixed my problem, but this is not the way...
