Hi,

For a Python program that reads Spss system files I (actually, the .so files from Spss Inc. need it.) need libimf.so, which is the Intel math Fortran library. I am on ubuntu 10 (32 bits).
I downloaded the libraries from the intel website*) I untarred them and ran ran make install.**) Then I tried loading the said .so file with Python ctypes, but I got and OSError ("undefined symbol: __ashldi3"; full traceback below). Any ideas how to solve this?
I tried loading a couple of other .so files from the same library, and they work.

Thanks in advance!

Unless your application is created 2011, a "2005-2009" 'libimf.so' may do ?

Hi Knudfl,

Thanks a lot for helping me! I'm a bit further now, and I've learnt a thing or two about Linux. Right after I installed libimf.so, I got an error that libstdc++.so.5 couldn't be found. So I installed that one, too. Now I get an error about libicui18n.so.32. I'm thinking, isn't it possible to, just like in the R statistical programming language (which is heavily influenced by Unix/Linux), do something like install.packages(pkgname, dependencies=TRUE).
I can't even find libicui18n.so.32 (at least not for my distro). Btw, is there never any risk that an older so-file version overwrites a newer one? Or will that never happen as long as alternative versions are never installed in /usr/lib ?

Okay, been tinkering with this long enough for now. Will drink some high-sulphite house wine *logging off* ;-)

Best wishes,
Albert-Jan

'libicui18n.so.32' : So it is some really old software !

Libicu34 is Ubuntu 6.10. ( Year 2006 ) No old icu32 packages.
( Old Debian used icu18, icu36.)

The files are in this package : libicu32-3.2-2mdk.i586.rpm ( 2005 )
ftp://ftp.sunet.se/pub/Linux/distrib...-2mdk.i586.rpm
Suggest : sudo alien libicu32-3.2-2mdk.i586.rpm : A package.deb will be created.
The file libicui18n.so.32 will not do alone : The files libicu***.so.X all depend
on each other. But no other dependencies : 'sudo dpkg -i <package>.deb' will do.

( Source code : icu-3.2 ).

What we have seen till now all have unique file names.
The intel files have different "hideaway locations".
( libicu32 , libicu40 , libicu42 can be installed at the same time.)
So the answer is : So far no conflicts.

..

Hi,

Thank you once again! I'll certainly try this. I'm planning to write a small shell script and call this from within Python if the needed files are not installed.


May I ask how you knew that the right files/versons are in this package? Is this expert knowledge? Or is there some way of finding such things out myself in the future? (other than becoming an expert myself ;-)

Thanks!

Actually this example is easy : The package libicu32 has these library names :
Real name = libicu***.so.32.0, "so name" = libicu***.so.32 .

( libicu40 : ***.so.40, libicu42 : ***so.42 ).

There are lots of examples, where the naming is not that obvious.
For later versions http://packages.ubuntu.com/karmic/libicu40
Then enter a file name in "Search" and choose 'package contents'
http://packages.ubuntu.com/search?se...bicui18n.so.40

Searching for an old file : http://rpm.pbone.net/ > Advanced search.
Not "deb" packages, but you will get information about the library-<version>,
that provides the file in question.
