Dear all!
I’ve just installed Haiku r1beta5-x86_64 as a QEMU/KVM virtual machine and started playing around, and then observed a weird gfortran compilation warning:
What is the cause of the message? and how can I avoid/fix this?
I guess it has something to do with how gfortran was built…
Thanks in advance.

I had reported it here before. Needs someone with the right set of skills to fix it.
Hello @KazuFurutaka, and welcome! It’s always a pleasure to see another Fortraner in Haiku.
I get the same warning, which is still there even if I inhibit all warning messages (gfortran -w ...). So if even that won’t suppress the warning message, I don’t know what else will. Clearly a bug, which I didn’t report since @BiPolar already did.
Despite that, however, gfortran works very well in Haiku. I use it extensively without issues, even with bindings to C low-level libraries (such as OpenGL, OpenAL, etc). Makefiles are basically the same as in any *nix-like system; in large projects, with custom libraries used, you might want to set the system’s default include and lib directories (with the -I flag while compiling and -L while linking). Other than that, there is no difference when working with gfortran (and GCC in general) in Haiku.
I often forget what operating system I am using, since all the tools needed are there anyway. So don’t let that little warning fool you.
Hi…
I don’t think I’m the right staff but I’ve submitted this PR.
This has been fixed for some time now (I forgot to mention that before), but only in 64-bit. Unfortunately it’s still present in 32-bit (gfortran-x86).
IIRC, GCC was having build failures on 32 bits, thus why it is still stuck at 13.3.0_2023_08_10-3 (built on 2025-01-17 04:38:40).
On x86_64, newest package version is: 13.3.0_2023_08_10-6.
