cygwin correct setup great full installation and proper usage features
Respect deep joyfully express universal!
Installed on the new cygwin disk; I try to compile ie actually test, I play
Дмитро@Komp /cygdrive/f/HeloWorld
$ g++ ublas_test.cpp -o ublas_test
ublas_test.cpp:1:42: fatal error: boost/numeric/ublas/vector.hpp: No such file or directory
#include <boost/numeric/ublas/vector.hpp>
^
compilation terminated.
I test cygwin, I try to compile. Why is my cygwin installed incorrectly?
Please explain to me how to set it up correctly.
I can't debug cygwin for days. Apparently the two compilers in my system result in an error anyway, but I haven't compiled a fairly simple example yet.
Code:
#include <boost/numeric/ublas/vector.hpp>
#include <boost/numeric/ublas/matrix.hpp>
#include <boost/numeric/ublas/io.hpp>
using namespace boost::numeric::ublas;
// "y = Ax" приклад
int main()
{
vector<double> x(2);
x(0) = 1; x(1) = 2;
matrix<double> A(2,2);
A(0,0) = 0; A(0,1) = 1;
A(1,0) = 2; A(1,1) = 3;
vector<double> y = prod(A, x);
std::cout << y << std::endl;
return 0;
}
But he can not find the files that exactly are there? What else is he? setup-x86 itself installed the files
In some directories, I have not corrected anything there.
Help me set up or install cygwin correctly!
I either do not understand or I can not download it correctly.
How do I fix the curve?
Ask me clarifying questions. Point me to resources where the right information is different.
Powerful request for help, about how you need a guide!

Thus, no compilation for a number of days has been successful! I just don't know how to set it up. What's more, I want to understand correctly how to actually use cygwin particularly well, in which situations especially well, different features.
