Cling compilation successful, but not make install

Hi, I got Cling to compile using the instructions that you made available http://root.cern.ch/drupal/content/cling-build-instructions. (By the way, why not using git submodules, rather than having users clone subdirectories? It would allow you to refer to specific revisions of the dependencies in the version control. )

Everything works well, I can run cling successfully from the build directory. However, running sudo make install fails at the stage:

Here is what I get

Any clue?

It seems that violently removing some assertions in the code of clang does the job. CGDebugInfo.cpp (line 3314) and Value.cpp (lines 342 to 346).

Hi,
It seems this is an issue with the version of clang you have. Did you try with gcc?
Cheers
Vassil

Well not recently. I am currently working with this build which is fine for now. ( I need to create a large vm to have enough ram for the compilation)
Btw, it would help keeping track of the revision of clang that should be checked out with cling if the required revision number to use was specified via the mechanism of git submodules rather than manually and separately cloning it in subdirectories of llvm.

Hi,

Are you suggesting submodules for the build script repo here raw.github.com/karies/cling-all … r/clone.sh or for cling itself? Cling is intentionally beneath llvm/tools, so I don’t see how to do it.

Cheers, Axel

One way to do this would be to create two submodules for cling and clang in your branch cling-patches of your fork of llvm. You could also create an empty git base repo with three submodules.

From the viewpoint of the base repository, a submodule is only a tracked file holding a revision number for the target repository, and no other information like the branch or anything else. It is the responsibility of the parent repository to point to revisions for the submodules that are consistent with each other.
