Re: IDL 5.2 crashes with Linux Mandrake 6.0

Hello,

I just ran into the same stuff today... I believe a couple of people have
suggested a solution in the past, targeted at the original Redhat 6.0
distribution.

Here's what *seems* (see below) works for Mandrake:

First, get the following two packages:

 - compat-glibc-5.2-2.0.7.1.i386.rpm
 - compat-libs-5.2-1.i386.rpm

and install them as root. You'll find them on any redhat mirror (like
ftp.redhat.com or ftp.uni-bayreuth.de) in the RPMS directory of the
distribution CD. For some reason, they are not included in the Mandrake
distribution.

Then, it is necessary to ensure that a) the correct (old) version of the
libraries is used _and_ the correct (old) version of the loader is used to
start up the idl-binary (not the shell-script in /usr/local/rsi/idl_5.2/bin). I
have patched that shell script to ensure both the correct setting for
LD_LIBRARY_PATH and the startup of the idl binary with the old loader, and
attach both the new shell script as well as a diff to this mail. Be careful not
to overwrite the old version!

Finally, this pathed script brings idl (and idlde and idlhelp and idldemo) up,
*BUT* - as Laurent Chardon stated a while ago - breaks everything inside IDL
which uses functions of the operating system, e.g. findfile and spawning shell
command from inside IDL. This can be circumvented by adding the line

  setenv, 'LD_LIBRARY_PATH='

in idlstartup.pro - which resets the environment again to make operating system
accesses possible. (NB: It might be necessary to let
/usr/local/rsi/idl_5.2/bin/bin.linux in the library search path - any
comments???)

This workaround seems to work for me, but: I have only tested this for an hour
or so, I have not used widget programs (apart from xloadct), I have not
used live tools or insight.  Accessing netCDF's, however, works as well (or so
it seems to me)

Could someone verify if this works? And also let people at RSI (and Creaso, who
sells IDL in Germany) know that it would really be nice to sell something that
works?

Hope this helps,

  Chris.
