cling Assertion failed: Pragma handler already exists for this identifier

[X] Checked for duplicates

Describe the bug

After compiling from source and running cling I immediately get an "Assertion failed" crash:

Assertion failed: (!InsertNS->FindHandler(Handler->getName()) && "Pragma handler already exists for this identifier!"), function AddPragmaHandler, file /wrkdirs/usr/ports/lang/cling/work/llvm-project-cling-llvm18-20250207-01/clang/lib/Lex/Pragma.cpp, line 938.

Maybe @eamjensen or @devajithvs have an idea.

Maybe this helps: https://sage.cct.lsu.edu/sbrandt/hpx-cling-jupyter/-/blob/d74740df1dea06d896ca59c6d3e2cb856dc46e2e/patches/clang_multi_parsers.diff ?

It certainly improves the situation! Cling now starts with a suspicious warning

ERROR in cling::CIFactory::createCI():
  resource directory /wrkdirs/usr/ports/lang/cling/work/.build/lib/clang/18 not found!

It seems to work fine, but after typing .q it crashes with

It feels that these sort of problems arise because the LLVM source I'm using is not matching what Cling expects. But I fail to figure out the proper LLVM tag needed for v1.2

Apr 04 '25 13:04 arrowd

Could you retry with branch ROOT-llvm18 on llvm-project and master on cling ?

Apr 04 '25 15:04 ferdymercury

Here are patches I ended up with to make it work: https://github.com/FreeBSD/freebsd-ports/commit/29d4ca63c51bc6a98236ffcf7de97f6d24a1ba50#diff-3550d82761cd363dfb84204b6d246f29c56fe7c8df7f3cca4c502300aadd5de7

I also noticed that Cling doesn't work at all if LLVM is built with assertions enabled.

Apr 05 '25 14:04 arrowd

Here are the patches and the Makefile which are currently required in order for build of root with builtin cling to succeed on FreeBSD: https://github.com/freebsd/freebsd-ports/tree/main/devel/root

Note that more patches were needed in the past, but these were adapted (and much improved) into the root source code thanks to @mkrzewic.

In particular, I also recall needing to hack my way around assertions, otherwise build of root would fail at “root cling stage 1” with assertions enabled.

I am very much in favor of getting cling into the ports tree on FreeBSD, such that root can simply be build with cling as a dependency! Let me know if and how I can help

Well, it is in already. Try it out and let me know if we need to adapt it for Root.

Apr 05 '25 15:04 arrowd

Hi, the recent FreeBSD patchset is easily grabbed from my root FreeBSD branch, I may have screwed up the author's id though (@eamjensen)

Thanks! Would you like to propose a PullRequest to the root repository ? so that they stay in sync.

Apr 05 '25 19:04 ferdymercury

@ferdymercury sure, just need to make sure it still builds :)

Apr 06 '25 08:04 mkrzewic

I took a stab at building ROOT on FreeBSD from within the ports tree (release 6.34.06 - "portrevision 0" - i.e. building from source https://root.cern/download/root_v6.34.06.source.tar.gz) with builtin_cling=OFF, builting_clang=OFF and builtin_llvm=OFF.

Made a few changes to the cling port

clang++: error: linker command failed with exit code 1 (use -v to see invocation)
ninja: build stopped: subcommand failed.
*** Error code 1

My suspicion is that both the cling-patched as well as unpatched clang and/or llvm are being invoked, and things then screw up, but I am currently at a loss as to how I can properly configure root with builtin_cling=OFF, builting_clang=OFF and builtin_llvm=OFF.

The need for find_package(zstd) also suggests to me that some CMake targets are either not exported correctly, or the wrong CMake configs are being used.

Any help would be much appreciated!

@guitargeek or @hahnjo have looked into the builtin llvm off option recently and might have a hint.
