Eigen CMake Error

[Estefania]

Hi, I am trying to finish the installation. When I use CMake to configure I get this error all the time:

Fetching subdirectory eigen3
Pulling …
CMake Error at SofaKernel/SofaFramework/SofaMacros.cmake:244 (message):
Failed to add external repository eigen3.

See logs in
C:/Users/Teffy/SOFA/build/external_directories/fetched/eigen3/logs.txt
Call Stack (most recent call first):
SofaKernel/SofaFramework/SofaMacros.cmake:261 (sofa_add_generic_external)
extlibs/CMakeLists.txt:15 (sofa_add_subdirectory_external)

I am installing SOFA v19.12

Could you please help me solve this error?

Thank you

When Eigen3 auto-fetch fails, you can either:
– check the error in C:/Users/Teffy/SOFA/build/external_directories/fetched/eigen3/logs.txt and fix it (or post it here to get help)
– remove completely C:/Users/Teffy/SOFA/build/external_directories/fetched/eigen3 and retry
– set SOFA_FETCH_EIGEN3=ON in CMake GUI and retry

Tell us if one of these 3 solutions worked for you.

Hi Guollaume,

Thank you for your answer. I’ve tried solution 2 and 3. Although, I am still getting the same error. I am going to post here the file then:

CMake Warning (dev) in CMakeLists.txt:
No project() command is present. The top-level CMakeLists.txt file must
contain a literal, direct call to the project() command. Add a line of
code such as

project(ProjectName)

near the top of the file, but after cmake_minimum_required().

CMake is pretending there is a “project(Project)” command on the first
line.

This warning is for project developers.  Use -Wno-dev to suppress it.

Hey,

@guillaumeparan could it be due to rights on the machine?

– I also have a similar problem with SofaPython3. The error When compiling says:

SofaTest: optional dependency SofaPython found, Python_test will be built
Fetching subdirectory SofaPython3
Pulling …
CMake Error at SofaKernel/SofaFramework/SofaMacrosConfigure.cmake:249 (message):
Failed to add external repository SofaPython3.

See logs in
C:/Users/User/SOFA/Build/Master/external_directories/fetched/SofaPython3/logs.txt

-In the logs file it says:

This warning is for project developers. Use -Wno-dev to suppress it.

-Can someone help me what to do?

Hi @estefania, sorry for the VERY late answer. Do you still have this issue?

Hi @ajay, you need to install Git on your computer. See https://gitforwindows.org/
