I just had to remove #include "includes.h" For me, gcc version 2.9-cygwin-990830, I got similar errors to you and others which I got rid of by fixing includes ... (except for one). daemon.c: In function `daemon': daemon.c:82: parse error before `kerneldll' daemon.c:83: `kerneldll' undeclared (first use in this function) daemon.c:83: (Each undeclared identifier is reported only once daemon.c:83: for each function it appears in.) daemon.c:87: parse error before `(' daemon.c:88: `RegisterService' undeclared (first use in this function) daemon.c:95: `RegisterService' used prior to declaration daemon.c:95: warning: implicit declaration of function `RegisterService' daemon.c:108: `_PATH_DEVNULL' undeclared (first use in this function) (I add the following includes) //#include #include #include #include #include #include #define HAVE_CYGWIN ANYWAY Two things .... (possibly caused by command line options?) 1. compiler doesn't like // comments 2. compiler doesn't like declaration of variables except at start of function The following compiles okay for me (with only the one error I introduced which you shouldn't have) int daemon(nochdir, noclose) int nochdir, noclose; { int fd; HINSTANCE kerneldll; DWORD (*RegisterService)(DWORD, DWORD); switch (fork()) { case -1: return (-1); case 0: break; default: #ifdef HAVE_CYGWIN /* * This sleep avoids a race condition which kills the * child process if parent is started by a NT/W2K service. */ sleep(1); /* * This is the code that I took from WinVNC * The best solution would be to enclose this in a IF Win9x clause * that is if I knew propers C syntax I could do this */ /* Obtain a handle to the kernel library */ kerneldll = LoadLibrary("KERNEL32.DLL"); if (kerneldll == NULL) break; /* And find the RegisterServiceProcess function */ RegisterService = (DWORD (*)(DWORD, DWORD)) GetProcAddress(kerneldll, "RegisterServiceProcess"); if (RegisterService == NULL) break; /* Register this process with the OS as a service! */ RegisterService(NULL, 1); #endif _exit(0); } if (setsid() == -1) return (-1); if (!nochdir) (void)chdir("/"); if (!noclose && (fd = open(_PATH_DEVNULL, O_RDWR, 0)) != -1) { (void)dup2(fd, STDIN_FILENO); (void)dup2(fd, STDOUT_FILENO); (void)dup2(fd, STDERR_FILENO); if (fd > 2) (void)close (fd); } return (0); } > > The source is at the end of this email. > > The problem may be easy to spot but its beyond me. I can help a bit with C and a little with cygwin but I don't do all that much cygwin+windows programming.
