Maybe it's a missing CMake option to get it to be generated and installed.
Could you try and open a pull request? This should help and I'm happy to walk you through anything else: https://github.com/Homebrew/homebrew/wiki/How-To-Open-a-Homebrew-Pull-Request-(and-get-it-merged)
Thanks!
@mikemcquaid At the time of opening I wasn't aware of the reason for this issue, otherwise I would have gladly opened a pull request to address it. I was planning on coming back and digging into it, but @xu-cheng beat me to it. Either way thanks for the quick attention on this. Happy Holidays.
FindEigen3.cmake is there now, however Eigen3 is still not found:
brew list eigen
/usr/local/Cellar/eigen/3.2.6/include/eigen3/ (364 files)
/usr/local/Cellar/eigen/3.2.6/lib/pkgconfig/eigen3.pc
/usr/local/Cellar/eigen/3.2.6/share/cmake/Modules/FindEigen3.cmake
cmake --find-package -DCOMPILER_ID=GNU -DLANGUAGE=CXX -DMODE=EXIST -DNAME=Eigen3
Eigen3 not found.
CMake Error: Problem processing arguments. Aborting.
as opposed to boost
cmake --find-package -DCOMPILER_ID=GNU -DLANGUAGE=CXX -DMODE=EXIST -DNAME=Boost
Boost found.
@jmtatsch do you have eigen
linked? Can you post brew info eigen
?
brew info eigen

That's strange, I'll try to reproduce it.
Ok I can reproduce what @jmtatsch is describing too and I think it might be a new thing introduced with a new cmake version. This didn't happen for me before and I can now workaround the issue by setting the CMAKE_MODULE_PATH
, but I really shouldn't have to. My intuition is that it is a problem with the fact that cmake is defaulting to files in /usr/local/Cellar/cmake/.../share/cmake/Modules
but the eigen
Formula has placed extra files in /usr/local/share/cmake/Modules
, creating a shadowing effect which prevents that file from being picked up by cmake.
Sorry forgot to mention I put together a repo to demonstrate the issue: https://github.com/wjwwood/eigen_test
@wjwwood @jmtatsch Please open a new issue. It's hard to track this in a closed PR.
OK, new issue is here https://github.com/Homebrew/homebrew/issues/44937
It seems that the upstream
FindEigen3.cmake
CMake Module is not getting installed in the Homebrew formula. Here it is at the current released tag,3.2.2
:https://bitbucket.org/eigen/eigen/src/1306d75b4a21891e59ff9bd96678882cf831e39f/cmake/FindEigen3.cmake?at=3.2.2
The Module seems exists in the
.deb
for Ubuntu Trusty (grep for cmake):http://packages.ubuntu.com/trusty/all/libeigen3-dev/filelist
But is missing from Precise:
http://packages.ubuntu.com/precise/all/libeigen3-dev/filelist
And I don't see it for our Homebrew bottle:
Maybe it's a missing CMake option to get it to be generated and installed.
