Centos6.编译安装pcre时出现的问题及完美解决

1、-bash: ./configure: 权限不够

解决&＃xff1a;chmod增加x执行权限

[root&＃64;localhost pcre-8.34]# ./configure
-bash: ./configure: 权限不够
[root&＃64;localhost pcre-8.34]# chmod &＃43;x ./configure


2、rpm包安装pcre卸载后的nodeps参数问题&＃xff0c;导致./configure出现问题&＃xff0c;进而没有makefile文件&＃xff0c;不能make

解决&＃xff1a;grep依赖pcre, 得先安装一个老版本的pcre,才能编译新版的pcre

checking how to run the C preprocessor... grep: error while loading shared libraries: libpcre.so.0: cannot open shared object file: No such file or directory
gcc -E
grep: error while loading shared libraries: libpcre.so.0: cannot open shared object file: No such file or directory
checking for grep that handles long lines and -e... configure: error: no acceptable grep could be found in /usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/xpg4/bin
[root&＃64;localhost pcre-8.34]# make
make: *** 没有指明目标并且找不到 makefile。 停止。

rpm包安装低版本的pcre&＃xff1a;
安装完成后./configure正常

3、make时出现问题

[root&＃64;localhost pcre-8.35]# make
CDPATH&＃61;"${ZSH_VERSION&＃43;.}:" && cd . && /bin/sh /lamp/pcre-8.35/missing aclocal-1.14 -I m4
/lamp/pcre-8.35/missing: line 81: aclocal-1.14: command not found
WARNING: &＃39;aclocal-1.14&＃39; is missing on your system.You should only need it if you modified &＃39;acinclude.m4&＃39; or&＃39;configure.ac&＃39; or m4 files included by &＃39;configure.ac&＃39;.The &＃39;aclocal&＃39; program is part of the GNU Automake package:<http://www.gnu.org/software/automake>It also requires GNU Autoconf, GNU m4 and Perl in order to run:<http://www.gnu.org/software/autoconf><http://www.gnu.org/software/m4/><http://www.perl.org/>
make: *** [aclocal.m4] 错误 127

解决&＃xff1a;

[root&＃64;localhost pcre-8.35]# autoreconf -ivf

之后的安装就正常了
