Could someone > help me with this? OK, now it's a different problem. It's not the compilation but the link. It cannot find scanDL function in the -lflow library. I think it has something to do with C vs C++. plugin_sensor_PL_main.c is a C file. First, I don't even understand how it could have worked before, if plugin_sensor_PL_main.c was using a C++ function (UIDocument::scanDL()). Also, I thought the BL had been converted to C++. So there are two options now: the first is to convert plugin_sensor_PL_main.c to a C++ file. The other (which I'll apply anyway) is to change (int data-flow/include/path.h): vector<string> envList(char *envName); void scanDL(bool debug=false); to extern "C" { vector<string> envList(char *envName); void scanDL(bool debug=false); } Anyway, I think this is a BL issue more than a PL (Overflow) issue. Jarl? Jean-Marc P.S. Could you run: nm /opt/overflow/lib/libflow.so | grep scanDL and send me the results
