Error installing Root 6 on Mac OS Sierra with Xcode 8.33

[S.Lee]

Hi everybody.
I’m trying to install Root 6.08/06 on Mac OS Sierra.
When I do install Root 6 following the instructions, I got error messages.
I’m using with OS: MAC Sierra 10.12.5
Xcode: 8.3.3
I’ve installed: xcode-select --install using homebrew
I’m configuring root with the following command:
After ‘make’ command was completely done, I did make install and then I got error messages.

cmake ../ -Dgminimal=ON -Dasimage=ON -Dmathmore=On -Dminuit2=ON -Dxml=ON -DCMAKE_INSTALL_PREFIX=../root_exec
make
make install

Error messages I’ve got.

Does someone know how to solve this?

Thanks.

@mato perhaps you know what this is about? Thanks!

Are you sure is an error? The problem is that when we build the executables we add RPATH to @loader_path/../lib in order to locate the libraries when these executables are used to run tests in the binary directory. Then, the installation in CMake tries to add it again notifying a duplication. For me this was more a warning than a fatal error.
