[llvm-dev] cuda cross compiling issue for target aarch64-linux-androideabi

[Bharath Bhoopalam via llvm-dev]

I was wondering if anyone has encountered this issue when cross compiling
cuda on Nvidia TX2 running android.

The error is
In file included from <built-in>:1:

The command I used  is following

prebuilts/clang/host/linux-x86/clang-4667116/bin/clang++ \
-v \
-target aarch64-linux-androideabi  \
--cuda-path=/cuda/targets/aarch64-linux-androideabi \
-I ./cuda/targets/aarch64-linux-androideabi/ \
-I ../platforms/android-24/arch-arm64/usr/include \
-I .prebuilts/ndk/current/sources/sources/cxx-stl/gnu-libstdc++/4.9/include
\
-I
prebuilts/ndk/current/sources/cxx-stl/gnu-libstdc++/4.9/libs/arm64-v8a/include
\
-I ndk/sources/cxx-stl/system/include \
-L ./cuda/targets/aarch64-linux-androideabi/lib \
-lcudart -lcudart_static -ldl -lrt -pthread \
-o axpy axpy.cu

clang version I am using is
Android (4667116 based on r326829) clang version 7.0.1 (
https://android.googlesource.com/toolchain/clang
76e4d638afc560ad21845fad570888bef8c18045) (
https://android.googlesource.com/toolchain/llvm
67f3e6a51d93777841e0fb6d07f71fdf343df239) (based on LLVM 7.0.1svn)
Target: aarch64--linux-android
Thread model: posix


I dont have any issues build this file for native platform (ubuntu14.04)
clang++
--cuda-path=/usr/local/cuda-8.0 \
-I /usr/local/cuda-8.0/include \
-L/usr/local/cuda-8.0/lib64  \
-lcudart -lcudart_static -ldl -lrt -pthread \
-o axpy axpy.cu

any guidance is appreciated.
