Geant4 and HepMC

faca87 · April 21, 2021, 8:08am

Hello, I’m trying to run a Geant4 simulation based on HepMC on windows Machine.

I installed vcpkg pthreads and it looks like it was succesfully

I installed HepMC and it looks like it was succesfully

but when I build the simulation I get error

Here the log
CMakeError.txt (1.2 KB)

it says that it can’t find pthread.h but I installed it by vcpkg it is in the directory C:\vcpkg\vcpkg\buildtrees\pthreads\src\49e541b66c-53502e357c.clean then I setted the enviroment variable path…moreover I also copied it in the building directory of the simulation…

@bmorgan maybe do you know the problem?
Thank you

The cause of the error is right there in the output, and nothing to do with pthread:

It couldn’t find the HepMC you installed at C:/Program Files/HepMC3-install, so try running Cmake again with:

cmake -DGeant4_DIR="C:\Program Files\geant4_10_07_p01_install\lib\Geant4-10.7.1"  -DCMAKE_PREFIX_PATH="C:/Program Files/HepMC3-install" "C:\setup"

How CMake finds packages is fully documented here and here

bmorgan · April 21, 2021, 1:39pm

Could you post the CMakeLists.txt you’re using please? I think there’s a mix up between HepMC and HepMC3 going on, so use of find_package etc.

faca87 · April 21, 2021, 2:39pm

Hello @bmorgan do you mean the CMakeList of the simulation?
If yes here
CMakeLists.txt (3.5 KB)

bmorgan · April 21, 2021, 4:12pm

Thanks for the info! What’s happening is that the application’s CMakeLists.txt is searching for HepMC, not the HepMC3 that you installed - so there are two things to try:

Try installing HepMC: HepMC / HepMC. I’m not sure of its status on Windows though. After installing it, say to C:/Program Files/HepMC-install, you can point CMAKE_PREFIX_PATH to it in the same way as suggested above
Try changing the find_package(HepMC REQUIRED) in the CMakeLists.txt to find_package(HepMC3 REQUIRED). With the cmake command from before that should find HepMC3 where you installed it. However… it’s likely that if the application really uses HepMC it may not compile and error out with messages about missing headers etc.

I’d try the first option, then the second if HepMC has issues building on Windows. HepMC3 is more actively developed by the looks of things, so may be better to migrate the application to that in the long term.

C:\Program Files\HepMC-build>

here the log CMakeOutput.txt (7.5 KB)

Then I tried to replace
find_package(HepMC REQUIRED)
by
find_package(HepMC3 REQUIRED)

the building was succesfully but when I runned the command

cmake --build . --config Release

I got this error

C:\setup\include\HepMCG4Interface.hh(36,10): fatal error C1083: Non è possibile aprire il file inclusione: ‘HepMC/GenEvent.h’: No such fil
e or directory (compilazione del file di origine C:\setup\src\B1PrimaryGeneratorAction.cc) [C:\setup\build\mainMCMC.vcxproj]

here the log
log1.txt (13.1 KB)

Then I tried replacing HepMC/GenEvent.h by HepMC3/GenEvent.h

in the include\HepMCG4Interface.hh

but I get the error

C:\setup\include\HepMCG4Interface.hh(36,10): fatal error C1083: Non è possibile aprire il file inclusione: 'HepMC3/GenE
vent.h': No such file or directory (compilazione del file di origine C:\setup\src\HepMCG4Interface.cc) [C:\setup\build\
mainMCMC.vcxproj]

here the log

log2.txt (13.0 KB)

then I replaced

HepMC3/GenEvent.h by C:\Program Files\HepMC3-install\include\HepMC3\GenEvent.h

then it didn’t find HepMC3/Units.h

C:\Program Files\HepMC3-install\include\HepMC3\GenEvent.h(13,10): fatal error C1083: Non è possibile aprire il file inc
lusione: 'HepMC3/Units.h': No such file or directory (compilazione del file di origine C:\setup\src\HepMCG4Interface.cc
) [C:\setup\build\mainMCMC.vcxproj]

So I copied all the header files in HepMC3 subdirectory
C:\Program Files\HepMC3-install\include\HepMC3\HepMC3

but everyttime it can’t find new things

Then I tried replacing HepMC/GenEvent.h by HepMC3/GenEvent.h

in the include\HepMCG4Interface.hh

but I get the error

C:\setup\include\HepMCG4Interface.hh(36,10): fatal error C1083: Non è possibile aprire il file inclusione: 'HepMC3/GenE
vent.h': No such file or directory (compilazione del file di origine C:\setup\src\HepMCG4Interface.cc) [C:\setup\build\

Right, the issue is that the executable is still trying to use/link to the HepMC headers via the HEPMC_... variables in the CMakeLists.txt. Try changing those to to HEPMC3_....

faca87 · April 22, 2021, 7:19am

Hello @bmorgan

1)I copied again the application (to have the original source files and not the modified one)

2)[I modified the CMakeList iin order to call HEPMC3

CMakeLists.txt|attachment](upload://f8e79gzq5e2OonktILrQrk5IJ9l.txt) (3.5 KB)

but I still get the error that it can’t find HEPMC

Moreover, I also tried to install HepMC (notice, I mean HepMC and not HepMC3) on my area in the machine of the laboratory (CMakeOutput.txt (47.6 KB) linux machine). Unfortunately, you can see …I got error to install it on this machine too

This is the same error as before - it’s looking for a HepMC header, but HepMC3 has been installed/looked for.

For the linux error with HepMC, see the HepMC project page and the install instructions

Hi @bmorgan.
In these months I used the simulation by ssh connection using the laboratory machine, because they installed HepMC on that machine. To run the simulation I had to write

/cvmfs/sft.cern.ch/lcg/contrib/CMake/3.14.2/Linux-x86_64/bin/cmake -DHEPMC_LIBRARIES=/home/xxxxx/lemmatb/HepMC-2.06.11/build/lib/libHepMC.so -DGeant4_DIR=/cvmfs/geant4.cern.ch/geant4/10.7.p01/x86_64-centos7-gcc8-optdeb-MT/lib64/Geant4-10.7.1/ ../

and it works.

Now I have to revive this topic because I need the visualization and it would be very slow the visualization by ssh.
I installed HepMC and it looks like was sucesfully (I had to modify a file to install HepMC on windows…the HepMC developers helped me to do it). You can see here the installation of HepMC

log_HepMC.txt (697.7 KB)

Then I tried to compile the simulation

I compiled in these way

cmake -DGeant4_DIR=“C:\Program Files\geant4_10_07_p01_install\lib\Geant4-10.7.1” -DHEPMC_INCLUDE_DIR=“C:\HepMC-install\include” -DHEPMC_LIBRARIES=“C:\HepMC-install\lib\HepMCfio.lib” “C:\setup”

but I get this error

error.txt (43.7 KB)

do you know how to fix it?

Thank you

sergio · August 2, 2021, 11:00am

You are getting a bunch of linker errors that look like this:

HepMCG4AsciiReader.obj : error LNK2019: riferimento al simbolo esterno … non risolto nella funzione …

This means that some of your code calls some external function which the linker does not find. The reason seems this:

LINK : warning LNK4044: opzione ‘/LC:/HepMC-install/lib -lHepMCfio’ non riconosciuta; verrà ignorata [C:\setup\build\mainMCMC.vcxproj]

Those options are the ones that would link your code with the HEPMCfio library, but the linker did not recognize it, and hence the library was not included. I think it may be because there is a space; there should be two options (/LC:/HepMC-install/lib and -lHepMCfio) but somehow they ended up as one.

Having a look at FindHEPMC.cmake, I do not think you are supposed to pass explicitly -DHEPMC_LIBRARIES directly to cmake; instead, you pass -DHEPMC_DIR=“C:\HepMC-install" and let FindPackage do its thing.

I am not sure if I could provide a solution, but at least I hope this helped. Good luck!

And if I may, it can be useful to change your language to English, so it easier to share your error logs

faca87 · August 2, 2021, 3:47pm

Hello @sergio and thank you

If I don’t pass the libraries, i.e. I compile like this

cmake -DGeant4_DIR="C:\Program Files\geant4_10_07_p01_install\lib\Geant4-10.7.1" -DHEPMC_INCLUDE_DIR="C:\HepMC-install\include" "C:\setup"

I get this error (i.e. it says to pass the libraries)

Could NOT find HepMC (missing: HEPMC_LIBRARIES)

as you can read in the log
log_libraries.txt (2.5 KB)

Sorry, I didn’t understand how shold write …can you write the full compilation command please?

Sorry, I’ve to check how to change the language.

sergio · August 3, 2021, 10:29am

You should not pass -DHEPMC_INCLUDE_DIR either, but -DHEPMC_DIR. FindPackage will try to find HepMC in the directory given by HEPMC_INCLUDE_DIR, and give values to both HEPMC_INCLUDE_DIR and HEPMC_LIBRARIES based on what it found. This is equivalent to how you pass -DGeant4_DIR and not -DGeant4_INCLUDE_DIR. The alternative way is to give both HEPMC_INCLUDE_DIR and HEPMC_LIBRARIES explicitly, but I think that my suggestion should work.

I would try this:

cmake -DGeant4_DIR="C:\Program Files\geant4_10_07_p01_install\lib\Geant4-10.7.1" -DHEPMC_DIR="C:\HepMC-install" "C:\setup"`

I’ve just tried to compilet how you suggested, but I get:

There’s still the same warning:

LINK : warning LNK4044: opzione '/LC:/HepMC-install/lib -lHepMCfio' non riconosciuta; verrà ignorata [C:\setup\build\mainMCMC.vcxproj]
HepMCG4AsciiReader.obj : error LNK2019: riferimento al simbolo esterno "public: __cdecl HepMC::WeightContainer::WeightContainer(class std::ve

APEAVGenEvent@2@XZ) [C:\setup\build\mainMCMC.vcxproj]

Which directly leads to the linking error I explained earlier.

As I said, FindHepMC.cmake seems to have a bug in this line:

set(HEPMC_FIO_LIBRARIES “-L${HEPMC_LIBRARY_DIR} -lHepMCfio”)

This works fine on Linux, but not on Windows.

I see multiple problems with the FindHepMC.cmake that is shipped with Geant4. Did you manage to build any of the HepMC examples on Windows? Because it does not look possible to me.

To address your current problem, you could try replacing FindHepMC.cmake with this modified version:

# in a directory defined via  HEPMC_ROOT_DIR or HEPMC_DIR environment variable
# Defines:
#
#  HEPMC_FOUND
#  HEPMC_INCLUDE_DIR
#  HEPMC_INCLUDE_DIRS (not cached)
#  HEPMC_LIBRARIES
#  HEPMC_FIO_LIBRARIES

find_path(HEPMC_INCLUDE_DIR HepMC/GenEvent.h
          HINTS $ENV{HEPMC_ROOT_DIR}/include ${HEPMC_ROOT_DIR}/include
          $ENV{HEPMC_DIR}/include ${HEPMC_DIR}/include)

find_library(HEPMC_LIBRARIES NAMES HepMC
             HINTS $ENV{HEPMC_ROOT_DIR}/lib ${HEPMC_ROOT_DIR}/lib
             HINTS $ENV{HEPMC_DIR}/lib ${HEPMC_DIR}/lib)

get_filename_component(HEPMC_LIBRARY_DIR ${HEPMC_LIBRARIES} PATH)

find_library(HEPMC_FIO_LIBRARIES NAMES HepMCfio
             HINTS $ENV{HEPMC_ROOT_DIR}/lib ${HEPMC_ROOT_DIR}/lib
             HINTS $ENV{HEPMC_DIR}/lib ${HEPMC_DIR}/lib)

set(HEPMC_INCLUDE_DIRS ${HEPMC_INCLUDE_DIR})

# handle the QUIETLY and REQUIRED arguments and set HEPMC_FOUND to TRUE if
# all listed variables are TRUE
INCLUDE(FindPackageHandleStandardArgs)
FIND_PACKAGE_HANDLE_STANDARD_ARGS(HepMC DEFAULT_MSG HEPMC_INCLUDE_DIR HEPMC_LIBRARIES HEPMC_FIO_LIBRARIES)

mark_as_advanced(HEPMC_FOUND HEPMC_INCLUDE_DIR HEPMC_LIBRARIES)

Let me know if that works. Pinging @kmura, in case the examples need to be fixed for Windows. I wonder what’s the status with HepMC, since they should be the ones providing the CMake config package.

Hello @sergio , it isn’t a Geant4 example. It’s a Test Beam setup simulation (here the source WeTransfer - Send Large Files & Share Photos Online - Up to 2GB Free) and I can’t find FindHepMC.cmake in the source.
I’ve only Cmakelist where HepMC is searched by

find_package(HepMC REQUIRED)
include_directories(${PROJECT_SOURCE_DIR}/include 
                    ${PROJECT_SOURCE_DIR}/process_channeling/include 
                    ${Geant4_INCLUDE_DIR}
                    ${HEPMC_INCLUDE_DIR} )
target_link_libraries(mainMCMC ${Geant4_LIBRARIES} 
                      ${HEPMC_LIBRARIES} 
                      ${HEPMC_FIO_LIBRARIES} ${PYTHIA6_LIBRARIES} )

should I add these lines

I am pretty confident that your simulation is based on one of Geant4 HepMC examples. This line

find_package(HepMC REQUIRED)

uses a FindHepMC.cmake file under the hood, which is shipped with Geant4 to support those examples.

If you check the CMake log that you posted on your first message, you can see that you are using it:

faca87:

CMake Error at C:/Program Files/CMake/share/cmake-3.20/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
  Could NOT find HepMC (missing: HEPMC_INCLUDE_DIR HEPMC_LIBRARIES)

This is the file you can try modifying C:/Program Files/geant4_10_07_p01_install/lib/Geant4-10.7.1/Modules/FindHepMC.cmake.

Could you please try to build those examples, before and after modifying the file? It would be nice to know if there is a problem on Windows that needs fixing.

faca87 · August 9, 2021, 12:00pm

Hello @sergio

First I tried to compile the examples

examples\extended\eventgenerator\HepMC\HepMCEx01 , but I got error

log_HepMCEx01.txt (9.7 KB)

2.examples\extended\eventgenerator\HepMC\HepMCEx02 , but I got error

log_HepMCEx02.txt (9.3 KB)

It looks like to me they are the same errors of the Test Beam simulation.

Then I modified the

C:/Program Files/geant4_10_07_p01_install/lib/Geant4-10.7.1/Modules/FindHepMC.cmake .

FindHepMC.cmake.txt (1.1 KB)

and I compiled the Test beam simulation and the example, but still getting errors

log_setup.txt (43.7 KB)

log_HepMCEx01_2.txt (10.6 KB)
