在 ARM Zynq（裸机）上使用 Eigen C++ 库

Question

在为 Zynq baremetal (Cross compile GNU Scientific Library for ARM Zynq ( baremetal )) 交叉编译 GNU Scientific 库失败后，我尝试改用 Eigen C++。

所以我下载它然后解压缩并包含它的 header 如下所示

-I/home/wizard/Desktop/eigen

代码在我的电脑上运行良好（x64 Ubuntu）但是一旦我将编译器从 gcc 更改为 arm-xilinx-eabi-gcc & g++ 到 arm-xilinx-eabi-g++ 代码给我以下错误：

invalid conversion from 'const int*' to 'const int32_t* {aka const long int*}' [-fpermissive]   test4       line 244, external location: /home/wizard/Desktop/eigen/Eigen/src/Core/arch/NEON/PacketMath.h   C/C++ Problem

我该怎么办？
