Toolchain is unable to link executables

Configuration failed. This could reflect a misconfiguration of your
toolchains, improper options selected, or another problem. If you
don't see any useful error messages above, the next step is to look
at the configure error log file (config.log) to determine what
configure was trying to do when it died.

I may have seen similar errors, reported but I didn't find any solution or any that worked.
How to fix it?

The text was updated successfully, but these errors were encountered:

erdemguven · 2019-05-21T17:09:36Z

I can reproduce this. I tried a range of NDKs from r10e to r19c.

andrewlewis · 2019-05-23T15:13:24Z

It looks like this may have been broken by 3169b14. The extension builds correctly for me with v1.7.0 and NDK r16.

andrewlewis · 2019-05-23T16:52:34Z

Another option that works for me is to switching generate_libvpx_configs to configure libvpx to do an external build, using NDK r19c and leaving the libvpx sources in v1.8.0.

@andrewlewis How do I do that?

I checked out branch v1.7.0

user@ubuntu:~/Downloads/ExoPlayer/extensions/vp9/src/main/jni/libvpx$ git checkout -b v1.7.0
Switched to a new branch 'v1.7.0

and then tried with NDK r16b, but also didn't work:

Configuration failed. This could reflect a misconfiguration of your
toolchains, improper options selected, or another problem. If you
don't see any useful error messages above, the next step is to look
at the configure error log file (config.log) to determine what
configure was trying to do when it died.

Update configuration script to use an external build, so we can remove use of isysroot which is broken in the latest NDK r19c. Also switch from gnustl_static to c++_static so that ndk-build with NDK r19c succeeds. Issue: #5922 PiperOrigin-RevId: 250287551

@andrewlewis @tonihei @ojw28 I changed the Application.mk and generate_libvpx_android_configs.sh file contents to the contents in the c495a3f commit. But then I get this problem when running ./generate_libvpx_android_configs.sh "${NDK_PATH}" with ndk r19c:

user@ubuntu:~/Downloads/ExoPlayer/extensions/vp9/src/main/jni$ ./generate_libvpx_android_configs.sh "${NDK_PATH}"
Usage: ./generate_libvpx_android_configs.sh

@s3433557 After that commit the script doesn't expect the NDK path to be passed any more (see the change to the readme in the same commit).
