Error running Geant4 examples macro with ROOT6 from trunk

[mr-xak]

This is cross-post from Geant4 forum.

I’m running ROOT6 built from git source, tagged as 6.27/01. While trying to run /examples/extended/medical/dna/chem6 example of Geant4 using the provided ROOT macros files the execution fails. With the ‘plotG_LET.C’ macro nothing happens, ROOT just exits withour warnings after several seconds, with ‘plotG_time.C’ macro there is an error like

Processing plotG_time.C...
Assertion failed: LV.getLinkage() == T->getLinkage(), file D:\dev\otherProjects\ROOT6\root_trunk4\interpreter\llvm\src\tools\clang\lib\AST\Type.cpp, line 3746

and also exits. With some older version of ROOT these macro were started succesfully.

Mentioning @Axel, @bellenot

---

ROOT6 installed using the git clone command, opening cmake-gui within VS Command Prompt x64 environment, choosing x64 default option, adding -Thost=x64 to additional commands, changing CMAKE_INSTALL_PREFIX, calling Configure double times, Generate one time, than following to the build folder and running

cmake --build .
cmake --build . --target install

[Axel]

Can you share the file CMakeLists.txt from your build directory, please?

@bellenot is the MSVC version the right one? Why do we have asserts on given the build steps mentioned above - is this even a release build?

[bellenot]

@Axel yes, this is the correct version of MSVC. @mr-xak please use this syntax to build ROOT on Windows:

cmake --build . --config Release

i.e. Specify the build type (Release, Debug, RelWithDebInfo)
And meanwhile I’ll try to reproduce the problem.

[mr-xak]

You mean CMakeLists.txt of Geant4 example or from ROOT that I’ve installed?

In ROOT Build directory there is no CMakeLists.txt, only CMakeCache.txt

[Axel]

Of ROOT, and yes I was distracted and meant CMakeCache.txt Thanks!

While trying to rebuild with the current upstream forgot another problem of x64, that it is not building with builtin_lzma

(sorry for russian output)

I need to explicitly uncheck this box in cmake-gui, and put the include/lib of pre-built liblzma.

I’ve put --config specification, rebuilt both x32 and x64 versions of ROOT using separate folders, and I can confirm that x32 version of the upstream having the same issue as described in the topic with Geant4 examples macros.

[bellenot]

I have no problem with LZMA. And I’m building Geant4 right now, will keep you updated

[mr-xak]

Here it is
CMakeCache.txt (123.4 KB)

[bellenot]

So the problem comes from the Geant4 macros. Please try with these ones:
plotG_LET.C (4.9 KB)
plotG_time.C (6.5 KB)

[mr-xak]

Yes, these macros runs succesfully as intended. Thank you very much!
Should I post this versions to Geant4 forum as the suggested modification?

[bellenot]

Yes, feel free to ask them, and please mention me, so they can come discuss with me if they want
