ubuntu“make”错误：hg：未找到

Question

I am trying to 'make' a project with ubuntu. I get this error :

sh: 1: hg: not found
make[3]: *** [/home/user/myproject/build/CMakeFiles/stamp/eigen3-download] Error 127
make[2]: *** [CMakeFiles/eigen3.dir/all] Error 2
make[1]: *** [all] Error 2
make: *** [externals] Error 2

What is the problem ?

Thanks

You need Mercurial. Install it with

sudo apt-get install mercurial
