I'm using the latest GIT, including the latest patches for tellico of last night. This is with Slackware 14.0 64-bit (gcc 4.7.1). I don't have the failure with Slackware 13.1 32-bit (gcc 4.4.4). The failure message: ================================== make[3]: Entering directory `/dev/shm/tellico/src' ... /bin/sh ../libtool --tag=CXX --mode=link g++ -Wno-long-long -Wundef -ansi
