Build Issue

[whoamibro]

Hello Barath, I'm facing build error issue.

I'm using ubuntu 18.04, OpenCV 3.4.14, gcc 10.3.0, g++ 10.3.0, libeigen3-dev 3.3.4

Could you please help me?

Hello, I also encountered a similar problem when building the project. How did you solve this problem?

The problem with this image is that I do not see what the error is (only a warning is shown). Could you please copy the error?

I'm using windows11, VSCode, OpenCV 3.4.16, gcc 8.1.0, g++ 8.1.0, eigen 3.3.9，cmake 3.22.0

mingw32-make[2]: *** [CMakeFiles\pygcransac.dir\build.make:91: CMakeFiles/pygcransac.dir/src/pygcransac/src/gcransac_python.cpp.obj] Error 1

Okay, but what is the error you get when trying to compile?
What you sent is not the error that you get, this only says that you got some error.

I encountered an error while executing C: Users\Masters\Desktop\graph-cut-ransac-master\build> mingw32-make.exe:

I think that error occurs due to the miss opencv version problem.
If you installed opencv4.X, you might see that error.
I solve that problem by degrade opencv version to 3.X

This is not an OpenCV problem. You should include math.h
You can also replace M_SQRT2 with sqrt(2).
