Hi, I have installed Garfield++ on lxplus but during building an example by using make , i found the attached error !! Does anyone know where exactly the problem and how to solve ?? /cvmfs/sft.cern.ch/lcg/releases/CMake/3.18.4-2ffec/x86_64-centos7-gcc10-opt/bin/cmake: /cvmfs/sft.cern.ch/lcg/extern…

Hi, there seem to be some inconsistencies in your environment (gcc 10 vs. gcc 4.8.4). How did you set it up? Can you try with an LCG view, for instance source /cvmfs/sft.cern.ch/lcg/views/LCG_99/x86_64-centos7-gcc10-opt/setup.sh

Thanks a lot , it is working , but when i run any example this error appear ,is it has a relation?? terminate called after throwing an instance of ‘std::logic_error’ what(): basic_string::_M_construct null not valid Aborted (core dumped)

Hi @Tahany , To me it seems that it doesn’t; the exception that you mentioned is thrown if you construct a std::string providing (const char *)nullptr as argument. We are missing important information, though; could you please attach the the code that you are trying to run? Cheers, J.

Hello @jalopezg Thanks for your response , the idea that , i get this error during running any Garfield++ example so , I thought that , anyway I attach a general basic example ( gem example) and i will try to mimic your solution into the others gem.C (4.5 KB) s . Best wishes, Tahany

The culprit might be the line const std::string path = getenv("GARFIELD_HOME"); Is this variable defined in your environment? What do you get when you type echo $GARFIELD_HOME

@hschindl I get this directory /cvmfs/sft.cern.ch/lcg/releases/Garfield++/HEAD-09e01/x86_64-centos7-gcc10-opt

Ah, sorry for that, I think that may be a side effect of some recent changes. Where is the Garfield++ source directory on your machine? Can you try re-setting the GARFIELD_HOME variable to this directory? Something like export GARFIELD_HOME=/home/user/path_to_garfield_src_dir

@hschindl , Exactly the problem was as you mentioned , it was in defining GAFIELD_HOME , now most of them are working well , thank you :slight_smile: but , what if I got this error , what do you think about ? terminate called after throwing an instance of ‘std::bad_alloc’ what(): std::bad_alloc …

Hm, that seems to be something else. Is this what you get when you run the gem.C program you sent earlier? Can you post/attach the full output you get when running the program?

No, it has no relation about garfield basic example , it is another one related to RPC. omponentNeBem3d::Initialise: Prepared weighting field for readout group “BotGra”. E = ( -0.00000000, -0.00000000 70833.71188276), V = 7083.37941689, status = -5 Sensor::AddElectrode: Added readout …

Can you attach the source code of the program?
