GXINT(1)

📦 version 2025.09.18.4, in nixos 26.05, nixpkgs unstable

💖 gxint — like, the manual page, bestie 💖

okay so this is gxint from the General Commands Manual, section 1. think of it as your little group-chat liaison to a whole entire GEANT vibe. let's get into it ✨

🦋 NAME 🦋

gxint — loads and runs an interactive GEANT application. that's the whole assignment, honestly. 🫶

🌸 SYNOPSIS 🌸

gxint [options] file(s)

✨ DESCRIPTION ✨

okay so gxint is a script — not a giant compiled beast, just a script — and what it does is load and run a GEANT application. and what's a GEANT application usually? Fortran source code, bestie. yes. Fortran. we respect her 🎀

the routines you actually want are the ones you hand over in file(s). that's the tea. 🔥

💅 OPTIONS 💅

  • -d driver — picks the graphics driver for you. on Linux the available choices are X11 and Motif (and Motif should also work with lesstif, ngl). X11 is the default, she's the main character 💅
  • -g geant_version — says which version of GEANT to use. current default is 3.21. highkey this option only makes sense if you installed some GEANT version other than 3.21 (like, one that wasn't packaged by Debian). iykyk 🧚
  • -h host — only useful with the -d X11 option, okurrr? it specifies the hostname used for the display, and the syntax is identical to that of $DISPLAY. if you don't give a hostname, the value of $DISPLAY gets used instead. slay 🖥️✨
  • -l library — adds extra libraries. you can repeat this option to add several libs, and honestly you probably will 💀
  • -L path — an additional loader search path. super useful when you've added extra libraries with the -l option. this one can also be repeated with more than one pathname 🎀
  • -m — do NOT use the main program from the cernlib area. that's it, that's the flag. no cap 🙈
  • -o outputfile — so instead of immediately running GEANT, you produce an executable file named outputfile. and if you don't pass -o? the executable file gets created in $HOME, named GEANTpid (where pid is the process ID of gxint), and it runs automatically. iconic behavior tbh 👑
  • -v version — specifies the version of $CERN_LEVEL. lowkey this is meaningless unless you've installed an upstream version of CERNLIB (i.e. not one packaged by Debian). go read /usr/share/doc/cernlib-base/README.Debian, it's all in there 📖💜
  • -?, --help — shows you a summary of the options. the little "what's what" moment 🌈

🍓 SEE ALSO 🍓

  • cernlib(1) — a script that lists the required -l and -L options when you give it a list of CERN libraries. bestie behavior, honestly 🫶
  • /usr/share/doc/cernlib-base/README.Debian — this describes how one might use the -v flag with Debian's versions of the cernlib and gxint scripts, if one has an upstream version of CERNLIB installed. conditional queen 💅
  • CERNLIB documentation for all the related libraries and programs lives at this URL: http://cern.ch/cernlib/ — go click, go learn 🌸

fr fr, don't skip the caveats — the -g and -v flags are basically only for upstream installs, and the -m flag is a "do NOT" so read it twice, bestie 😭
