While installing Ottendorf version of SER , I am facing following compilation errors /usr/bin/ld: cannot find -l_ser_cds collect2: ld returned 1 exit status make[1]: *** [dialog.so] Error 1 /usr/bin/ld: cannot find -l_ser_xcap collect2: ld returned 1 exit status make[1]: *** [pa.so] Error 1 /usr/bin/ld: cannot find -l_ser_xcap collect2: ld returned 1 exit status make[1]: *** [presence_b2b.so] Error 1 /usr/bin/ld: cannot find -l_ser_xcap collect2: ld returned 1 exit status make[1]: *** [rls.so] Error 1 What would be the problem??? -Venkat
