1.编译《UNP》 http://www./unpv13e.tar.gz 我们首先产生一个目录，以后自己的代码就敲在这个目录里。 mkdir /home/hehe/study/unp 仍然是下载到/home/hehe/download/，解压缩，进入目录 cd /home/hehe/download/unpv13e/ README 文件中说的很详细： ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ Execute the following from the src/ directory: ./configure # try to figure out all implementation differences cd lib # build the basic library that all programs need make # use "gmake" everywhere on BSD/OS systems cd ../libfree # continue building the basic library make cd ../libroute # only if your system supports 4.4BSD style routing sockets make # only if your system supports 4.4BSD style routing sockets cd ../libxti # only if your system supports XTI make # only if your system supports XTI cd ../intro # build and test a basic client program make daytimetcpcli ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ 这里只编译lib下的文件，这样可以产生libunp.a，复制这个静态库到/usr/lib/和/usr/lib64/ 如果提示： unp.h:139: error: conflicting types for ‘socklen_t’ /usr/include/bits/socket.h:35: error: previous declaration of ‘socklen_t’ was here 需要注释掉当前目录中unp.h的第１３９行。 复制libunp.a到系统目录： root@dan-laptop:/home/hehe/download/unpv13e/lib# cp ../libunp.a /usr/lib root@dan-laptop:/home/hehe/download/unpv13e/lib# cp ../libunp.a /usr/lib64/ 2.使用unp.h和libunp.a 如果直接复制unpv13e/lib/unp.h和config.h到/usr/include，那么在别的目录编译书上代码时，很可会得到类似下面的错误： In file included from daytimetcpsrv1.c:1: /usr/include/unp.h:227: error: redefinition of ‘struct sockaddr_storage’ In file included from daytimetcpsrv1.c:1: /usr/include/unp.h:249:30: error: ../lib/addrinfo.h: No such file or directory /usr/include/unp.h:263: error: redefinition of ‘struct timespec’ /usr/include/unp.h:363: error: conflicting types for ‘gai_strerror’ /usr/include/netdb.h:647: error: previous declaration of ‘gai_strerror’ was here /usr/include/unp.h:367: error: conflicting types for ‘getnameinfo’ /usr/include/netdb.h:653: error: previous declaration of ‘getnameinfo’ was here /usr/include/unp.h:371: error: conflicting types for ‘gethostname’ /usr/include/unistd.h:857: error: previous declaration of ‘gethostname’ was here /usr/include/unp.h:387: error: conflicting types for ‘inet_ntop’ /usr/include/arpa/inet.h:65: error: previous declaration of ‘inet_ntop’ was here /usr/include/unp.h:395: error: conflicting types for ‘pselect’ /usr/include/sys/select.h:121: error: previous declaration of ‘pselect’ was here daytimetcpsrv1.c: In function ‘main’: daytimetcpsrv1.c:9: error: ‘MAX_LINE’ undeclared (first use in this function) daytimetcpsrv1.c:9: error: (Each undeclared identifier is reported only once daytimetcpsrv1.c:9: error: for each function it appears in.) dan@dan-laptop:~/study/unp/4$ rm -f /usr/include/unp.h 这是因为unp.h包含config.h使用的是#include "../config.h",而此时unp.h和config.h的位置关系发生了变化，只需改为#include "./config.h"即可 |
