OK, I've looked at the log file that Bob sent me and compared it to what I see on my machines. The difference appears to be something in libtool. My machine (works): /bin/sh ../../../libtool --tag=CXX --mode=link g++ -g -O2 -Wall -Woverloaded-virtual -pthread -o test_mblock test_mblock.o libmblock-qa.la libmblock.la g++ -g -O2 -Wall -Woverloaded-virtual -pthread -o .libs/test_mblock test_mblock.o ./.libs/libmblock-qa.so /home/eb/gr/trunk/mblock/src/lib/.libs/libmblock.so /usr/lib/libcppunit.so -ldl ./.libs/libmblock.so /home/eb/gr/trunk/pmt/src/lib/.libs/libpmt.so /usr/lib/libstdc++.so Bob's machine (doesn't work): /bin/bash ../../../libtool --tag=CXX --mode=link g++ -g -O2 -Wall -Woverloaded-virtual -pthread -o test_mblock test_mblock.o libmblock-qa.la libmblock.la g++ -g -O2 -Wall -Woverloaded-virtual -pthread -o .libs/test_mblock test_mblock.o ./.libs/libmblock-qa.so ./.libs/libmblock.so -Wl,--rpath -Wl,/usr/local/lib Although they both make the same call to libtool, libtool spits out a different command line on the two systems. On Bob's (and I assume Illix's) machine, the output of libtool contains --rpath (pointing to the install, not build directory!), whereas my machine lists the actual paths needed to find the pieces. Bob's machine is using ltmain.sh (GNU libtool) 1.5.22 Debian 1.5.22-4 (1.1220.2.365 2005/12/18 22:14:06) I'm using (SuSE 10.1) ltmain.sh (GNU libtool) 1.5.22 (1.1220.2.365 2005/12/18 22:14:06) It looks like the Debian folks may have applied some kind of a patch to libtool 1.5.22 that could be causing the problem. Can any debian/ubuntu users figure out the difference? That is, what's the debian/ubuntu patch, and when and why was it applied?
