LibCXX Build errors Android 7.0.0_r1

[Daniel Dawson]

Hello,

I'm building Android 7.0 when I encountered a string of errors halfway though the build from LibCXX. I'm using Arch Linux and I had no trouble building Android 6. I know I'm missing something obvious:

In file included from external/libcxx/include/vector:264:

typedef __char16_t char16_t;

         ^

template <unsigned> struct __static_assert_check {};
^
external/libcxx/include/__config:583:10: error: expected identifier or '('
template <unsigned> struct __static_assert_check {};

I'm not sure what is causing this.

Many Thanks,
DD

Can you provide the full error message, everything from the line that
starts with FAILED: to the beginning of the next command (it will look
like [###/###]).

Thank you for your reply,

Thank you very much for your help.

You left out the line that starts with FAILED:, which lists the exact
command that failed.

It appears you are trying to compile with device/asus/grouper, which
has been removed from the tree and is no longer supported. Did you
manually add that back to your source tree?

[Daniel Dawson]

As for building for Grouper, it does come from Android 5.1; although I have made some minor modifications to allow it to run later versions of Android. I was able to build and run Android 6 successfully. I think that it is a library issue, though I could be wrong.

Many Thanks,
DD

The framework dumpstate was converted to c++, grouper's libdumpstate
needs to be converted to match. See
https://android.googlesource.com/device/htc/flounder/+/1ef2d9feeaf70605c04884f61205bd2ac8815574
for an example of the same change made for flounder.
