redhat8 and ubuntu22 all broken compilations

[teuben]

software rot in action. gfortran needs the -std=legacy by now, the compiler is getting pretty strict by now. For U22 this is V11.2. On RH8 even gfortran 8.5 is misbehaving.

<rpc/rpc.h> is also missing now.

no doubt more to come.

rpc: commented it out in one code, it was never needed.

u22 now compiles. fedora36 still has the pgsbox that doesn't get compiled, but it worked fine on redhat8. This means at some point a future rh (rh9?) may fail.

According to my other notes, this was due to a libc upgrade, so for rpc you need a new package:

ubuntu: make sure you've installed tirpc: sudo apt install libtirpc-dev

redhat: libtirpc-devel-1.1.4-8.el8.x86_64 (your version may be different)

One also needs an extra compiler flag: -I/usr/include/tirpc

Is there an actual guide here (or anywhere else) to get this to compile on Ubuntu 22.04 ?

[teuben]

have a look at the script docs/install_miriad.sh - this is what i usually use to compile. Compilation of pgplot can be done with our own internal version or with the version that comes with ubuntu. the latter is preferred, as it has the PNG device drivers.

I did a quick test on ubuntu 25.04 - has linking failures. Will look into it.
