Hello all, I download the most recent stable version of plib and tried to compiled it win mandrake 8.1. I received the following error: make[2]: Entering directory `/usr/src/plib-1.4.2/src/net' c++ -DPACKAGE=\"plib\" -DVERSION=\"1.4.2\" -DHAVE_LIBDL=1 -DHAVE_LIBGL=1 -DH AVE_LIBGLU=1 -DHAVE_LIBGLUT=1 -DHAVE_GL_GL_H=1 -DHAVE_GL_GLU_H=1 -DLINUX_JOY STICK_IS_PRESENT=1 -DGLUT_IS_PRESENT=1 -I. -I. -I../../src/util -I/usr/lo cal/include -g -O2 -O6 -Wall -c netSocket.cxx netSocket.cxx: In method `int netSocket::accept (netAddress *)': netSocket.cxx:218: cannot convert `int *' to `socklen_t *' for argument `3' to `accept (int, sockaddr *, socklen_t *)' netSocket.cxx: In method `int netSocket::recvfrom (void *, int, int, netAddress *)': netSocket.cxx:256: cannot convert `int *' to `socklen_t *' for argument `6' to `recvfrom (int, void *, unsigned int, int, sockaddr *, socklen_t *)' make[2]: *** [netSocket.o] Error 1 make[2]: Leaving directory `/usr/src/plib-1.4.2/src/net' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/usr/src/plib-1.4.2/src' make: *** [all-recursive] Error 1 Where shoud soklen_t be defined? I assuming I just need to include an another .h file, just am not sure which one. |

(To the original author: typedef'ing "socklen_t" to be "int" is not a solution. Passing a pointer to your home-made type to a library function is dangerous, since nobody gurantees that the "socklen_t" of the C library and your definition have the same size. "man recv" explicitly says that both "sys/socket.h" and "sys/types.h must be included. I guess including "sys/types.h" will fix the problem for you. Please try it and report if it did so that we can fix this bug in CVS. - Sebastian |

The problem is, however, that by not including "sys/types.h", the current code even typedef's "socklen_t" to be "int" on machines that *do* define socklen_t, which can be fatal when it comes to pointers to those types. As the manuals of standard-conforming UNIX systems do, I really suggest including "sys/types.h" in addition to "sys/socket.h". It is a standard header file - does IRIX miss it, too ? If yes, just add a check for it in configure.in. - Sebastian |

Clearly we should be including that header - but we may need conditional compilation to use socklen_t only if it's defined and fall back on an 'int' instead. To be honest though, it's hard to imagine a socket system whose internal structure was more than 2^32 bytes long! ----------------------------- Steve Baker ------------------------------- Mail : <sjb...@ai...> WorkMail: <sj...@li...> URLs : http://www.sjbaker.org http://plib.sf.net http://tuxaqfh.sf.net http://tuxkart.sf.net http://prettypoly.sf.net http://freeglut.sf.net http://toobular.sf.net http://lodestone.sf.net |
