  • I don't really have enough context to be 100% certain as to what the problem is but my first thought would be that if your program is calling the following method

    void sleep(unsigned int);

    from stdlib.h then your program needs to link against libcmt.lib

  • Thanks to both of you for your replies,

    I actually sorted out the problem this afternoon, the previous error is result of duplicated main( ).
    The second one i guess you guys were correct on sleep( ), i tried with sleep( ) and Sleep( ) but it did not work.
    Actually i am a java programmer, but i need to use this 3rd party code which is written in C and integrate to my java project. As the result facing problem in C.

    Now i face a new problem: the include file sys/times.h. MS VS.net 2003 and other window-base compiler does not have this file. But some said that put the header file is not enough but i need to have the .lib and linker for that as well. So i am stuck

    Any suggestion would be very much appreciated

    thanx,
    C

  • What method(s) do you need for sys\times.h? Visual C++ 2005 ships with a sys\utime.h and a sys\timeb.h. The chances are that the function(s) you need is/are in these header files.
