<div class="PlainText">Hi there<br>
<br>
I am writing to get a bit of help with installing 31DEC26 on Debian 13,<br>
which was released in Aug 2025.<br>
<br>
The AIPS binary distribution (Linux 64-bit) wants libreadline7, but this is<br>
not available in this release of Debian (libreadline8 was introduced<br>
in 2020 and is now the default).<br>
<br>
First question: is there a binary distribution that uses libreadline8?<br>
<br>
I decided to try a TEXT install. I managed to get everything to build<br>
but it was a struggle so I thought I should write in to get some advice.<br>
<br>
Second question: are some tweaks needed?<br>
The issues I bumped into are enumerated below.<br>
Happy to hear any advice.<br>
<br>
In the end I was able to RUN FILAP, RUN POPSGN and RUN SETPAR, and start aips.<br>
I have not tried loading data or displaying images yet.<br>
<br>
Kind regards<br>
Vince<br>
<br>
<br>
1. Building libreadline5 fails<br>
<br>
I won't go into details here but worked around this by setting<br>
<br>
READLINE = /usr/lib/x86_64-linux-gnu/libreadline.so<br>
<br>
in .AIPSRC. I don't the bundled source will compile on this platform.<br>
<br>
2. XAS compilation<br>
<br>
The system compiler is gcc 14 (and gfortran 14).<br>
The default for this compiler is -fno-common and this<br>
caused a lot of 'multiple definition of <foo>' errors,<br>
I think because all the .c modules #include xas.h.<br>
<br>
To get the XAS code to compile I made this change to the Makefile<br>

4. Missing 'libbsd' package causes a link-time failure<br>
