[Xymon] Library Errors on Solaris 9

[Root, Paul]

Solaris binary compatibility is guaranteed going up not going down.

Actually, I have libresolv.so.2 on my last few Solaris 9 boxes.

Did you do an "ls -l /usr/lib/libresolv.*"?

Ultimately, you need to compile on Solaris 9, and that will run on Solaris 9 and Solaris 10.

Subject: [Xymon] Library Errors on Solaris 9

Hi all

Encountered an interesting problem installing my Xymon client on Solaris 9.
I have solved it, but it's interesting enough that I felt it was worth sharing with the list.
And maybe get some feedback on other approaches.
The client was compiled on Solaris 10, so I was expecting the Solaris binary compatibility thing to make it all "just work" when I copied the client to Solaris 9.
But that would be too easy. :-/

Most of the binaries gave this issue.
ld.so.1: /usr/local/xymon/client/bin/msgcache: fatal: libresolv.so.2: version `SUNW_2.2.2' not found (required by file /usr/local/xymon/client/bin/msgcache)
zsh: killed     /usr/local/xymon/client/bin/msgcache

Looks like libresolve.so.2 is missing

The library is there
# grep libresolv.so.2 /var/sadm/install/contents
/usr/lib/libresolv.so=./libresolv.so.2 s none SUNWcsl
/usr/lib/libresolv.so.2 f none 0755 root bin 316552 9398 1268771224 SUNWcsl
/usr/lib/sparcv9/libresolv.so=libresolv.so.2 s none SUNWcslx
/usr/lib/sparcv9/libresolv.so.2 f none 0755 root bin 385952 24889 1268771224 SUNWcslx

And we have the LD_LIBRARY_PATH set correctly.
% echo $LD_LIBRARY_PATH
/opt/svrexp/dvlpr/2.2/lib:/usr/openwin/lib:/usr/lib:/opt/cics/lib:/opt/dcelocal/lib:/opt/encina/lib:.

So I checked to see if there was another issue, and it turns out it can see libresolv.so.2, but wants a specific version.
# ldd /usr/local/xymon/client/bin/msgcache
        libresolv.so.2 =>        /usr/lib/libresolv.so.2
        libresolv.so.2 (SUNW_2.2.2) =>   (version not found)
        libsocket.so.1 =>        /usr/lib/libsocket.so.1
        libnsl.so.1 =>   /usr/lib/libnsl.so.1
        librt.so.1 =>    /usr/lib/librt.so.1
        libc.so.1 =>     /usr/lib/libc.so.1
        libdl.so.1 =>    /usr/lib/libdl.so.1
        libmp.so.2 =>    /usr/lib/libmp.so.2
        libaio.so.1 =>   /usr/lib/libaio.so.1
        libmd5.so.1 =>   /usr/lib/libmd5.so.1
        /usr/platform/SUNW,Sun-Fire-V240/lib/libc_psr.so.1
        /usr/platform/SUNW,Sun-Fire-V240/lib/libmd5_psr.so.1

Then I recalled hearing about the LD_NOVERSION parameter you can set, which causes the the runtime linker to ignore version requirements.
A bit of reading here also helped. http://docs.oracle.com/cd/E19963-01/html/819-0690/docinfo.html
I added the following 2 lines to the top of the ~/client/runclient.sh script
LD_NOVERSION=1
export LD_NOVERSION
Restarted, and it all worked fine.

Maybe some of the programmer types can provide us with some feedback on the correctness of this approach, or even provide a better solution, but for now, it's working.

Regards
     Vernon
