I fixed the previous problem by adding the path in the Makefiles. Then I get this error: ----------------------------------- ... gcc -shared -o vflowmodule.so -Wl,--rpath -Wl,`/opt/overflow/bin/overflow-config libflow --libs` mod_vflow_wrap.o -L/usr/lib -lxml -lz -lstdc++ -lpthread /usr/local/bin/ld: cannot find -lflow ----------------------------------- Testing the overflow-config command... ----------------------------------- $ /opt/overflow/bin/overflow-config libflow --libs -L/opt/overflow/lib -lflow ----------------------------------- Okay... ----------------------------------- $ ls -l /opt/overflow/lib total 16071 16070 -rwxr-xr-x 1 root root 16389193 Sep 1 02:28 libflow-0.6.so* 1 -rwxr-xr-x 1 root root 655 Sep 1 02:28 libflow.la* 0 lrwxrwxrwx 1 root root 14 Sep 1 02:28 libflow.so -> libflow-0.6.so* ----------------------------------- Seems to be there, right?
