Hi All, I have a problem at Linker stage in the compilation process. If I include libsqlplus.so as -lsqlplus it is generating the binary otherwise it is the giving undefined reference to sqlca function. I have also given the LD_LIBRARY_PATH etc. Because I have to change at lot number of places , is there a way around so that i can dynamically include this library for example through ranlib. Regards, Vivek
