We are about to upgrade our production system to 2.2.8. One of the biggest problems that I am fighting is the rpath issue. Basically, it is important for the binaries (imapd, pop3d, etc) to be able to find both the SSL libs and the SASL2 libs. When I configure the server, I set LDFLAGS to set the appropriate rpath options so that when I do compile the server, it will include the library paths in the binaries.
Basically, it looks like this:
export CC="cc" export LDFLAGS="-Wl,-rpath,$SSLDIR/lib:$SNMPDIR/lib:$SASLDIR/lib"
./configure --with-sasl=SASLDIR --with-openssl=$SSLDIR ......
What is the problem? The problem is that it doesn't work. The compiler on Tru64 (cc), does not handle multiple rpath options on the command line in the same way that gcc does. In fact, Tru64 expects only one rpath option on the command line, and if there are multiple rpath's specified, only the last one on the command line will be accepted.
The proper way to handle this in Tru64 is to make the path colon delimited (as in the above LDFLAGS setting) and make sure that it appears as the only one on the command line, or that it appears last on the command line.
This is now how it works with Cyrus... the configure process builds the rpath stuff as it is configuring it. Since I set the LDFLAGS stuff before configuration, the configure script puts it first on the command line. As it builds the libraries that it must include (using the -L and -l stuff), it adds to the command line and adds additional rpath options as well, which override the previous ones. The end result is that my binaries are dumb with how to find all but one of the shared libraries.
The only solution that I have right now is to hack all the Makefile's after the configuration process has completed to remove the extra rpaths. That is quite painful. The other thing I could do is hack the startup scripts to set LD_LIBRARY_PATH, and hack the perl scripts to do the same and make sure that anything we write that interfaces with Cyrus does the same too.
Personally, I would rather see it solved at configuration time, but I have yet to figure out a way to do so.
Any ideas?
There doesn't seem to be a way to force configure to either create an appended form of a single rpath, or to not build rpath information at all. Either method would work for me.
Thanks,
Scott
