I am trying to install db2 Express Edition on slackware 10.2
The install script generates an error:
error: Failed dependencies:
libc.so.6(GLIBC_2.2) is needed by IBM_db2cliv81-8.1.0-105
/bin/sh is needed by IBM_db2cliv81-8.1.0-105
The installation logfile can be found in /tmp/db2_install_log.7810.
db2_install program terminated prematurely.
what do I need to do to resolve this?
/bin/sh is definitely there. So is /lib/libc.so.6 (and /usr/lib/libc.so.6).
The current version on my system appears to be glibc_2.3.5 - do I need an older one?
If so what do I need to do?
you can probably do it, but because the binary has been compiled with specific versions of things, you might need to actually install those exact versions ... that's what sucks about closed source binaries.
glibc-2.2 is what was used in Slackware 8.1 and there is no binary compatibility between binaries compiled for glibc-2.2 and the glibc-2.3 or later libraries.
You may be able to get the thing to work by installing the glibc-2.2 libs, bu you should not try to install them anywhere in your regulat library paths as they will interfere with your currently installed libs and probably whack your system. You could take an old slack-8.1 package and open it up with explodepkg and copy the libs into some unique directory, say /usr/local/lib/oldglib.
Then try to run the program by passing LD_LIBRARY_PATH to the binary:
LD_LIBRARY_PATH=/usr/local/lib/oldglib:$LD_LIBRARY_PATH /usr/local/bin/db2 (or whatever path).
I still doubt that you'll be able to do all this successfully without getting into a very invloved process(recompiling glibc-2.2 so it will co-exist with glibc-2.3(maybe have to recompile 2.3 also)). Plus you are probably going to have still more missing stuff.
Perhaps a better way would be to use qemu to run an old version of slack to run the program in.
