When using cmake -DCMAKE_INSTALL_PREFIX=… , I get errors at lines 83 and 84 of tools/cling/CMakeLists.txt saying that 5 arguments are required.
I deleted those lines as they are not related to OS X and the build scripts get generated.
Then I do cmake --build . --config Release --target cling and I get an include file not found error reported below. It seems that the LLVM/clang current sources do not have that .inc file anymore…
Can you please help?
Thanks,
Alessandro

I am also having problems building on OSX (cmake) according to the posted instructions as well as the cpt.py tool. In particular, cpt.py exits with unexepected test failures . Can anybody provide a reliably-working build procedure for OSX and cling master?
Also, is cling pinned at an old version of llvm, or is there any chance cling might work against llvm >=3.5?
Finally, I’m trying to build cling from source because I want to try to embed the interpreter in another program. Can this be done from the binary releases? (Do the binaries ship with includes?)
Here’s my procedure:
Checkout cling (twice?), clang, and llvm:
cling/ <-- checkout of cling from root.cern.ch/git
cling/build <-- I created this dir, and it’s the current working dir below
cling/src <-- checkout of llvm from root.cern.ch/git and checkout out cling-patches branch (commit 4f6e66a29b)
cling/src/tools/cling <-- also a checkout of cling (is this right?)
cling/src/tools/clang <-- checkout of clang from root.cern.ch/git and checkout out cling-patches branch (commit 89ccdaef)
in cling/build, I run:
$ cmake -DCMAKE_INSTALL_PREFIX=pwd …/src
(completes ok)
$ cmake --build . --config Release --target cling – -j8
This fails with a traceback similar to the one in the OP:

I have also tried the autotools/configure route (following how Travis is set up on the github cling site) and get a similar error.
When I try to use cpt.py with either --current-dev tar or --last-stable, I get unexpected tests failures

Also, is there a verified-working build procedure for linux? I’ve tried running all this in ubuntu utopic (via Docker on mac) and so far the VM OOMs before compilation finishes… but lots of broken builds on Travis here: travis-ci.org/vgvassilev/cling
I don’t see where we say that src/ should contain the cling sources? They should end up only in src/llvm/tools/
We have patches on top of llvm + clang; you cannot use the original sources. Moving cling to current clang + llvm is on my list for this year, likely for begin December.
And FYI, the llvm + clang we use is from February.
src/ is the llvm source code as the instructions specify. src/ is within a cling checkout; I was seeing some CMake errors without this but perhaps I wasn’t building cleanly.
Can you not reproduce the clang/AST/DeclNodes.inc or cpt.py errors? What’s a stable version of cling?
I found the llvm version number reference, I guess this is llvm 3.5 then? Thanks!
CMake setup is broken for OSX 10.9. It might be that cling is actually OK and llvm/clang CMake setup is actually broken for OSX: llvm.org/bugs/show_bug.cgi?id=11232
cpt.py is perhaps broken. AFAICT, the only major difference between cpt.py and clone.sh is --enable-targets=host, which might be significant on OSX due to how Apple sets up the dev tools.
Axel, I believe you authored clone.sh. I noticed it sets up a nice local install with (I believe) the patched clang and llvm. If I wanted to integrate cling in an app, could I just include and link against this local install? Is this effectively what ROOT would do?
