hi Keith thank you very much for pointing out the orders. I definitely overlooked the issue. After putting -lgw32c -lole32 at the end of the command line, the linking error for drand48_r has gone. However, there are still 10s of unresolved references error for stderr, stdin and stdout. Are there anything else I overlooked? > Also, .obj looks wrong for GCC; while the format may be correct, .o > is the more normal object file extension. > I deliberately set it to .obj for windows, although setting it to .o shall be equally ok.
