FORTRAN(1)

👑 FORTRAN(1) — the NAME era 💅

okay bestie, so Fortran — and yes this is the User Commands corner of the manual, section 1, iykyk — is out here doing one (1) job: it reports statistics regarding an HDF5 file and the objects in the file. that's the whole vibe. periodt. ✨

🦋 DESCRIPTION 🦋

so here's the usage, and no I did not make this up, this is literally what it says:

usage: h5fc [OPTIONS] <compile line>

✨ OPTIONS ✨

• -help — the help message. it helps. iconic behaviour honestly 🫶
• -echo — shows you all the shell commands it executed. full transparency, no gatekeeping 💖
• -prefix=DIR — the prefix directory where it goes looking for the HDF5 lib/ and include/ subdirectories. default is /usr. she has a comfort zone 💅
• -show — shows you the commands without executing them. look, don't touch 🌸
• -showconfig — shows the HDF5 library configuration summary 📋
• -shlib — compile with shared HDF5 libraries ✨
• -noshlib — compile with static HDF5 libraries. and this one is the default 🎀
• <compile line> — the normal compile line options for your compiler. yes, your actual compiler's actual flags. main character energy for your compiler fr fr

ngl, here's the tea: h5fc uses the same compiler you used to compile HDF5. check with your compiler's man pages for more info on which options are needed — she's not gonna guess for you, bestie 😭

and you can override the compiler and the linker to compile your program by setting these environment variables accordingly:

• HDF5_FC — use a different Fortran 90 or 95 compiler 🔥
• HDF5_FLINKER — use a different linker
• HDF5_USE_SHLIB=[yes|no] — use shared or static version of the HDF5 library. default: no

🧚 the "you can also tweak paths and flags" section 💜

you can also add or change paths and flags to the compile line using the following environment variables — or by assigning them to their counterparts in the 'Things You Can Modify to Override...' section of h5fc. yes that's the actual name of the section. we love a descriptive queen ✨

Variable → Current value to be replaced

• HDF5_FFLAGS → ""
• HDF5_LDFLAGS → ""
• HDF5_LIBS → ""

⚠️ okay important one, don't skip this: note that adding library paths to HDF5_LDFLAGS where another hdf5 version is located may link your program with that other hdf5 library version. so like… be careful. that's not a vibe, that's a bug waiting to happen 💀

and that's the whole page, babe — it's Fortran from the Debian 4.6.1-4 packaging, version 4.6.1, dated August 2011, filed under FORTRAN(1). retro queen. she ate and left no crumbs 🎀✨🦋
