我正试图用CUDA代码编译一些TensorFlow本机操作。
更具体地说:
gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.10)
GNU C++11 (Ubuntu 5.4.0-6ubuntu1~16.04.10) version 5.4.0 20160609 (x86_64-linux-gnu)
compiled by GNU C version 5.4.0 20160609, GMP version 6.1.0, MPFR version 3.1.4, MPC version 1.0.3
编辑:
我用CUDA9.0和CUDA9.1以及各种编译器后端通过
-compiler-bindir clang++
或
-compiler-bindir gcc-4.8
,而且总是相同的错误。
测验铜:
// For Eigen::GpuDevice.
#define EIGEN_USE_GPU 1
// For Eigen::ThreadPoolDevice.
#define EIGEN_USE_THREADS 1

(添加

获取更多的编译器版本信息,尽管这里似乎没有相关信息。)

看看这段代码
string_view.h
:
static constexpr size_type CheckLengthInternal(size_type len) {
return ABSL_ASSERT(len <= kMaxSize), len;
}
哪里
ABSL_ASSERT
定义(在
absl/base/macros.h
// ABSL_ASSERT()
//
// In C++11, `assert` can't be used portably within constexpr functions.
// ABSL_ASSERT functions as a runtime assert but works in C++11 constexpr
// functions. Example:
//
// constexpr double Divide(double a, double b) {
// return ABSL_ASSERT(b != 0), a / b;
// }
//
// This macro is inspired by
// https://akrzemi1.wordpress.com/2017/05/18/asserts-in-constexpr-functions/
#if defined(NDEBUG)
#define ABSL_ASSERT(expr) (false ? (void)(expr) : (void)0)
