g2o compilation

[anagno]

Hello,

I would like to use ORB_SLAM in windows and I came up to your repository. I was able to compile DBoW2 but unfortunatelly I was not able to compile compile g2o. Is is possible to give some more instructions on how to compile ORB_SLAM on windows?

Thank you in advance,

Vasilis

I am facing the same issue too. Can you post the solution if you have solved it.

Thanks,

Yes I get the error:

CMake Error at cmake_modules/FindBLAS.cmake:393 (message):
A required library with BLAS API not found. Please specify library
location.
Call Stack (most recent call first):
CMakeLists.txt:85 (FIND_PACKAGE)

What do you recommend for blas?

The original ORB_SLAM2 g2o CMakeLists.txt file has removed the following two lines, and it seems to work:

-    FIND_PACKAGE(BLAS REQUIRED)
-    FIND_PACKAGE(LAPACK REQUIRED)

I also removed the g2o cmake_modules folder, since it apparently isn't needed either. I think it works because BLAS and LAPACK are in Eigen3?

I've also created another issue (#9) which has solutions to other problems you might come across that aren't necessarily g2o related.
