无法编译oneAPI示例

Question

我安装了oneAPI工具，并试图编译示例项目vector-add。

make all
dpcpp -O2 -g -std=c++17 -o vector-add-buffers src/vector-add-buffers.cpp
In file included from src/vector-add-buffers.cpp:22:

                                           ^

我怀疑这是由旧的cmake、pkg-config、make、gcc和g++造成的，但我没有对集群的根访问权限。我试着用conda重新安装它。反正也无济于事。

Answer 1

为了用dpcpp编译器编译向量添加示例代码，gcc版本至少应该是7.3.0或更高版本。

您可以自己编译gcc (这很容易)，并使用export CXX=/path/gcc-9.2.0/bin/g++和export CC=/path/gcc-9.2.0/bin/gcc为cmake设置编译器env。
