Compiling a Geant4 based software, but get an error in root

Hi Root community,

Can you give me a hint about this compiling problem of a software that uses root and it’s Geant4 based, here I get a root compiling problem with make only. However it’s compiled fine in the first attempt, but I did a lot and forgot what I did wrong to get this error message. notice that I am using a binary distro but my ubuntu version is 21, that why you see the cling message.

ERROR in cling::CIFactory::createCI(): cannot extract standard library include paths!

It seems to me that your ROOT binary distribution (uses gcc 9) is incompatible with your operating system (uses gcc 11).

There’s what @Wile_E_Coyote said, and there might be a mismatch in C++ standard versions used to compile these ROOT headers. IIRC in ROOT 6.22 we give a more helpful message for this case, and this isn’t an issue anymore in 6.24.

Hi Axel, sorry for late reply. I figured it out, by installing and configuring the appropriate gcc and g++ versions.

No problem, thanks for letting us know!
