一：pcre简介：
PCRE(Perl Compatible Regular Expressions中文含义：perl语言兼容正则表达式)是一个用C语言编写的正则表达式函数库，由菲利普.海泽(Philip Hazel)编写。PCRE是一个轻量级的函数库，比Boost之类的正则表达式库小得多。PCRE十分易用，同时功能也很强大，性能超过了POSIX正则表达式库和一些经典的正则表达式库。 二：编译： sudo tar -zxvf pcre-8.39.tar.gz -C . sudo chown -R aston pcre-8.39 mkdir install_lib sudo ./configure --prefix=/home/aston/huawei/pcre-8.39/install_lib sudo make sudo make install 三：遇到的问题：1.报错1： aston@ubuntu:/mnt/hgfs/share/source_insight/main_135/test_pcre$ ./app.out ./app.out: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory原因：程序找不到pcre相关动态库； 解决： 拷贝pcre相关库到：/usr/local/lib/ aston@ubuntu:~/huawei/pcre-8.39/install_lib/lib$ sudo cp *pcre* /usr/local/lib/ -rf重新测试运行正常： aston@ubuntu:/mnt/hgfs/share/source_insight/main_135/test_pcre$ ./app.out good_afmbone..se result is: 0 四：测试：1.代码： #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include "pcre.h" #include #include using namespace std; #define OVECCOUNT 30 /* should be a multiple of 3 */ #define EBUFLEN 128 #define BUFLEN 1024 int main() { pcre *reCM, *reUN, *reTC, *reCDMA; const char *error; int erroffset; int ovector[OVECCOUNT]; int rcCM, rcUN, rcTC, rcCDMA, i; /* yidong:134.135.136.137.138.139.150.151.152.157.158.159.187.188,147 liandong:130.131.132.155.156.185.186 dianxin:133.153.180.189 CDMA :133,153 */ char src[22]; char pattern_CM[] = "^1(3[4-9]|5[012789]|8[78])\\d{8}$"; char pattern_UN[] = "^1(3[0-2]|5[56]|8[56])\\d{8}$"; char pattern_TC[] = "^18[09]\\d{8}$"; char pattern_CDMA[] = "^1[35]3\\d{8}$"; printf("please input your telephone number \n"); scanf("%s", src); printf("String : %s\n", src); printf("Pattern_CM: \"%s\"\n", pattern_CM); printf("Pattern_UN: \"%s\"\n", pattern_UN); printf("Pattern_TC: \"%s\"\n", pattern_TC); printf("Pattern_CDMA: \"%s\"\n", pattern_CDMA); reCM = pcre_compile(pattern_CM, 0, &error, &erroffset, NULL); reUN = pcre_compile(pattern_UN, 0, &error, &erroffset, NULL); reTC = pcre_compile(pattern_TC, 0, &error, &erroffset, NULL); reCDMA = pcre_compile(pattern_CDMA, 0, &error, &erroffset, NULL); if (reCM==NULL && reUN==NULL && reTC==NULL && reCDMA==NULL) { printf("PCRE compilation telephone failed at offset %d: %s\n", erroffset, error); return 1; } rcCM = pcre_exec(reCM, NULL, src, strlen(src), 0, 0, ovector, OVECCOUNT); rcUN = pcre_exec(reUN, NULL, src, strlen(src), 0, 0, ovector, OVECCOUNT); rcTC = pcre_exec(reTC, NULL, src, strlen(src), 0, 0, ovector, OVECCOUNT); rcCDMA = pcre_exec(reCDMA, NULL, src, strlen(src), 0, 0, ovector, OVECCOUNT); if (rcCM printf("Sorry, no match ...\n"); } else { printf("Matching error %d\n", rcCM); printf("Matching error %d\n", rcUN); printf("Matching error %d\n", rcTC); printf("Matching error %d\n", rcCDMA); } free(reCM); free(reUN); free(reTC); free(reCDMA); return 1; } printf("\nOK, has matched ...\n\n"); if (rcCM > 0) { printf("Pattern_CM: \"%s\"\n", pattern_CM); printf("String : %s\n", src); } if (rcUN > 0) { printf("Pattern_UN: \"%s\"\n", pattern_UN); printf("String : %s\n", src); } if (rcTC > 0) { printf("Pattern_TC: \"%s\"\n", pattern_TC); printf("String : %s\n", src); } if (rcCDMA > 0) { printf("Pattern_CDMA: \"%s\"\n", pattern_CDMA); printf("String : %s\n", src); } free(reCM); free(reUN); free(reTC); free(reCDMA); return 0; }2.打印： aston@ubuntu:/mnt/hgfs/share/source_insight/main_135/test_pcre$ ./app.out please input your telephone number 15000732435 String : 15000732435 Pattern_CM: "^1(3[4-9]|5[012789]|8[78])\d{8}$" Pattern_UN: "^1(3[0-2]|5[56]|8[56])\d{8}$" Pattern_TC: "^18[09]\d{8}$" Pattern_CDMA: "^1[35]3\d{8}$" OK, has matched ...
