Hi all,
I am trying to build Sage 4.4.1 from sourece, using gcc 4.4.1 on SUSE 11.2.
So far I have had two failures. I can work around the first, but have no clue
about the second.
Best, Paul
1. Problem with libreadline
Symptom:
[...]/local/lib/libreadline.so.6: undefined symbol: PC
Workaround:
Try to use native librealine.

There is something strange about readline on OpenSUSE. There some code which
does something different on OpenSUSE to other platforms. Perhaps that is not
working correctly. It looks a bit of a hack if I'm honest. I don't have time to
look at it now, but if you find the readline-$version.spkg, you will find there
is something in there which checks a header file and makes a decision based on
the header file. It may be that the test does not work on OpenSUSE 11.2.
2. Problem with symmetrica
Symptom:
/bin/bash: symbol lookup error:
[...]/spkg/build/symmetrica-2.0.p5/src/nb.c:4087: undefined reference to `cos'
Workaround:
???
Perhaps it needs the maths library linked, -lm, as that is where 'cos' will be.
Though that seems a strange thing to be missing.
Extracts from install.log:
1. Problem with libreadline
readline.c:1112: warning: ‘reset_default_bindings’ defined but not used
This, and the tons of other warnings worries me.
search.c: In function ‘_rl_nsearch_init’:
search.c:213: warning: too many arguments for format
How the hell do the developers let that get by? What the **** where they
thinking to ignore such a warning?
complete.c: In function ‘fnwidth’:
complete.c:643: warning: implicit declaration of function ‘wcwidth’
That probably needs
#include <wchar.h>
added to a source file.
../search.c: In function ‘_rl_nsearch_init’:
../search.c:213: warning: too many arguments for format
IMHO, it would be better if compilers would throw this as an error.
/bin/bash: symbol lookup error:
/home/leopardi/src/sage/sage-4.4.1/local/lib/libreadline.so.6: undefined
symbol: PC
Successfully installed readline-6.0.p1
So readline installs, despite the fact the code looks as though it could do with
a major cleanup to me.
It is clearly is the cause of many later problems.
sage: An error occurred while installing sqlite-3.6.22
sqlite is a well tested bit of code. The developers take testing very seriously
- see
http://www.sqlite.org/testing.html
sage: An error occurred while installing symmetrica-2.0.p5
I would look over the readline.spkg and see if there are any clues there. I
think you will find some SUSE specific code there, which may just not work.
