Visual studio code 设置用于消除特征的Vscode
我正在使用Eigen库()进行一些计算 我正在运行的程序是:Visual studio code 设置用于消除特征的Vscode,visual-studio-code,vscode-debugger,eigen3,Visual Studio Code,Vscode Debugger,Eigen3,我正在使用Eigen库()进行一些计算 我正在运行的程序是: #include <iostream> #include <Eigen/Dense> using Eigen::MatrixXd; int main() { MatrixXd m(2,2); m(0,0) = 3; m(1,0) = 2.5; m(0,1) = -1; m(1,1) = m(1,0) + m(0,1); std::cout << m <<
#include <iostream>
#include <Eigen/Dense>
using Eigen::MatrixXd;
int main()
{
MatrixXd m(2,2);
m(0,0) = 3;
m(1,0) = 2.5;
m(0,1) = -1;
m(1,1) = m(1,0) + m(0,1);
std::cout << m << std::endl;
}
如果我运行这个,它会编译并运行。。。但是现在我希望能够通过代码进行调试

此配置只运行代码,但不将调试器固定在代码上
非常感谢您的帮助 好的,这对我来说很有效: 1º下载特征值:
https://eigen.tuxfamily.org/index.php?title=Main_Page
2º创建指向eigen文件夹的符号链接
sudo ln -s location/of/Eigen/Folder /usr/local/include/
3º可以使用以下工具编译代码:
g++ my_program.cpp -o my_program
4º要“更好地调试”,请使用gdb的自定义python打印机
https://gitlab.com/libeigen/eigen/-/blob/master/debug/gdb/printers.py
a) Create a hidden file called gdbinit
touch ~/.gdbinit
b) Place the following code in it:
python
import sys
sys.path.insert(0, '/path/to/eigen/printer/directory') #In my case it was /home/pc/eigen/debug/gdb
from printers import register_eigen_printers
register_eigen_printers (None)
end
注意:VScode是开箱即用的(F5和调试模式是打开的!)
