Few issues on compiling the program on MacOSX
Opened this issue · 9 comments
- Runs into error when compiling with GCC-9, seems to only work with Clang
- Does not seem to have Eigen included, cannot seem to link it...
You have to use git clone --recursive for this assignment, since Eigen is included as a submodule of libigl, which is the only direct submodule on this assignment. Since you've already cloned, use git submodule update --init --recursive instead.
I'll reopen this since I'm sure others will have this issue and leaving it open improves visibility.
I re-cloned it and after trying to compile it here is the issue...
Thanks for pointing this out. I've pushed a fix, so it should work if you pull the latest version of the repo.
I still cannot find even after git submodule update --init --recursive.
Also tried find ./ -name "*igen" after update but get nothing either.
Do you see the libigl directory? If you do, then Eigen should be located at computer-graphics-bounding-volume-hierarchy/libigl/external/eigen.
I didn't see external folder inside libigl. Even on the github repo for libigl at header 230df4d. I cannot find external folder either.
It turns out that Eigen is not a submodule of libigl, but instead it downloads Eigen through its CMake config. Our CMake file is configured to build libigl as well, so if you follow the usual cmake instructions from this repo, it will build libigl, which will in turn download Eigen.
Great, it works now! Thanks! Didn't know you can download the module with cmake, that's neat.
