Libtool is linking the wrong library (location) in and I can't figure out what's causing it.

[Jim Lynch]

I have two fairly identical gnu make/build projects.  One of them works 
fine but the other is looking for the library in the wrong place.  The 
difference I see is that one of them has this:

ibtool: link: g++ -std=c++0x -g -O2 -o loggerd loggerd-fieldlist.o 
loggerd-t2m.o loggerd-loggercounters.o loggerd-loggerbase.o 
loggerd-dbutil.o loggerd-ftplogparser.o loggerd-infocache.o 
loggerd-inputqueue.o loggerd-outputqueue.o loggerd-imagenode.o 
loggerd-arcmessage.o loggerd-xmlrpc_client.o loggerd-emailthread.o
...
-lxmlrpc++ -lxmlrpc -lxmlrpc_util 
/home/jwl/build/usr/local/lib/liblog4cplus.so -pthread -Wl,-rpath 
-Wl,/home/jwl/build/usr/local/lib -Wl,-rpath 
-Wl,/home/jwl/build/usr/local/lib

whereas the last bit of the one that works has:
libtool: link: g++ -g -O2 -o vaprobe protoarduino.o pdbutil.o timer.o 
arcserver.o probethread.o protocamera.o protosimple.o vaprobe.o 
svn_version.o  -L/usr/lib64/mysql -limageserver-0.4.1 -lmysqlpp 
-lboost_regex -lmysqlclient -lpthread -lssl -lccgnu2 -lcurl -lccext2 
-ldl -lxml2

In the first case the previous line starts with:

/bin/sh ../libtool --tag=CXX   --mode=link g++ -std=c++0x   -g -O2 -o 
loggerd
Followed by the list of .o files and libraries.

In the working one, it's similar:

/bin/sh ../libtool --tag=CXX   --mode=link g++  -g -O2   -o vaprobe

One other difference is that in the first (bad) output I see two lines:

libtool: link: warning: library `/usr/local/lib/libimageserver-0.4.1.la' 
was moved.
libtool: link: warning: library `/usr/local/lib/libimageserver-0.4.1.la' 
was moved.
But not in the good run.

Where exactly is the -Wl flag coming from?  The Makefile.am files are 
essentially identical, except for the extra '-std=c++0x' and file 
differences.

My configuration in both cases looks like

./configure --prefix=/home/jwl/build/usr/local --sysconf=/home/jwl/build/etc


I do the build via a
make install prefix=~/build/logger/usr/local sysconfdir=~/build/logger/etc
rpmbuild --buildroot=$HOME/build/logger/ -bb logger.spec

And the spec files are structurally the same.

I don't think there are any environment variables set outside of the 
scripts.

Any information would be most appreciated.

Thanks,
Jim.
