c++ - 在ARM Zynq(裸机)上使用Eigen C++库

Question

在无法针对Zynq裸机(Cross compile GNU Scientific Library for ARM Zynq ( baremetal ))交叉编译GNU Scientific库之后，我尝试改用Eigen C++。

所以我下载了它，然后解压缩并包含如下所示的标题

-I/home/wizard/Desktop/eigen

该代码在我的PC(x64 Ubuntu)上可以正常工作，但是一旦我将编译器从gcc更改为arm-xilinx-eabi-gcc和g++更改为arm-xilinx-eabi-g++，代码就会给我以下错误:

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 ？
