Android compile issues (clang)

[israelillan]

Hi all,

I'm trying to compile libvlc, I'm using ubuntu 64bits (16.04) and following the guide here: https://wiki.videolan.org/AndroidCompile/

But I'm getting some errors I cannot find solutions to (I've looked around, sorry if I missed something and I'm reposting this problems).

When I try to compile (./compile.sh) after following every step i get an error:

*** No ANDROID_ABI defined architecture: using ARMv7

Which seems to be about not being able to find clang, here is the config.log contents:

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.69. Invocation command line was

The main problem seems to be:
/usr/bin/ld: cannot find -lgnustl_static

But the previous line:
/usr/bin/ld: skipping incompatible /home/isra/Android/Sdk/ndk-bundle/sources/cxx-stl/gnu-libstdc++/4.9/libs/armeabi-v7a/libgnustl_static.a when searching for -lgnustl_static
And all the warnings about clang ignoring some attributes make me think that maybe installing ubuntu's clang is not the way to solve the original issue.

Any ideas?

[Jean-Baptiste Kempf]

Delete everything and clone the HEAD of the git, with NDKr13

[israelillan]

Thanks Jean-Baptiste that made it work!

I was trying to compile the tag 2.0.6 (to be sure it was stable) I guess I was wrong.

[Jean-Baptiste Kempf]

Compiling 2.0.6 is tricky with clang.

Hi Jean-Baptiste
I compiling HEAD with sdk 24.1.1 ndk r13 with Ubuntu 16.04 64bit
always get the below error message

It may be a bug in the current commit, try commit from October 7th (fdb66fbfbbc2fe44596a9b0fcd1f75fd91e58c6a) it works like a charm for me

[dreamsong]

Israelillan,thanks
Hope it can be fixed asap!

[Jean-Baptiste Kempf]

It is fixed since then.
