Bug 266841 – sci-mathematics/pari-2.3.4-r1 links against old readline shared lib

• Product: Gentoo Linux
• Status: RESOLVED TEST-REQUEST

[Description Adrian Bassett 2009-04-20 10:39:32 UTC]

After upgrading readline to 6.0, sci-mathematics/pari-2.3.4-r1 became part of the preserved-rebuild portage set.  It was re-emerged with 'emerge @preserved-rebuild' but still appeared in the same set.  Running ldd on /usr/bin/gp-2.3 shows the dependency on version 5 of readline:

# ldd /usr/bin/gp-2.3
...
libreadline.so.5 => /lib/libreadline.so.5 (0xb7f1d000)
...

Repeating the same operation did not change anything, nor did running revdep-rebuild, or un-merging pari altogether before re-installing.

Reproducible: Always

Steps to Reproduce:
1.Upgrade readline to 6.0
2.Re-emerge pari-2.3.4-r1
3.

Actual Results:  
pari still links against the preserved version 5 readline shared library.


I notice that /lib/libreadline.so remains a symlink to libreadline.so.5 - is that expected?

Re-emerging readline-6.0 does not change anything:

# ls /lib/libreadline*
lrwxrwxrwx 1 root root     16 Apr  4 11:41 /lib/libreadline.so -> libreadline.so.5
lrwxrwxrwx 1 root root     18 Apr  4 11:41 /lib/libreadline.so.5 -> libreadline.so.5.2
-r-xr-xr-x 1 root root 209828 Apr  4 11:40 /lib/libreadline.so.5.2
lrwxrwxrwx 1 root root     18 Apr 20 11:22 /lib/libreadline.so.6 -> libreadline.so.6.0
-r-xr-xr-x 1 root root 218068 Apr 20 11:22 /lib/libreadline.so.6.0

(Please note that many other apps were re-emerged without problem after the readline upgrade and only pari and ipsec-tools (which is a separate issue - linux-headers version - for which a separate bug has been filed) remain problematic.

Many thanks.

This problem should go away when you remove /lib/libreadline.so.5 from your system (maybe it's better to not delete the file but move it out from /lib) and re-compile sci-mathematics/pari.

Re-open this bug if my suggestion doesn't work for you.

In the end I unmerged both ipsec-tools and pari (blockers on removing readline v.5 stuff) which left just v. 6 readline libs.  Pari re-installed OK at that point.  So, problem worked round.

Many thanks.
