今天小编就为大家分享一篇关于PHP安装BCMath扩展的方法,小编觉得内容挺不错的,现在分享给大家,具有很好的参考价值,需要的朋友一起跟随小编来看看吧。
编译安装 (PHP-5.6.23)
1.进入PHP源码包目录下的ext/bcmath目录。
[root@192 bcmath]# ls
bcmath.c config.m4 config.w32 CREDITS libbcmath package.xml php_bcmath.h tests
2.执行phpize命令,phpize命令在PHP安装目录的bin目录下,如/usr/local/php/bin/phpize。
- [root@192 bcmath]# /usr/local/php/bin/phpize

- /bin/sh /home/tools/phptools/php-5.6.23/ext/bcmath/libtool --mode=compile cc -I/home/tools/phptools/php-5.6.23/ext/bcmath/libbcmath/src -I. -I/home/tools/phptools/php-5.6.23/ext/bcmath -DPHP_ATOM_INC -I/home/tools/phptools/php-5.6.23/ext/bcmath/include -I/home/tools/phptools/php-5.6.23/ext/bcmath/main -I/home/tools/phptools/php-5.6.23/ext/bcmath -I/usr/local/php/include/php -I/usr/local/php/include/php/main -I/usr/local/php/include/php/TSRM -I/usr/local/php/include/php/Zend -I/usr/local/php/include/php/ext -I/usr/local/php/include/php/ext/date/lib -DHAVE_CONFIG_H -g -O2 -c /home/tools/phptools/php-5.6.23/ext/bcmath/bcmath.c -o bcmath.lo
- mkdir .libs
- cc -I/home/tools/phptools/php-5.6.23/ext/bcmath/libbcmath/src -I. -I/home/tools/phptools/php-5.6.23/ext/bcmath -DPHP_ATOM_INC -I/home/tools/phptools/php-5.6.23/ext/bcmath/include -I/home/tools/phptools/php-5.6.23/ext/bcmath/main -I/home/tools/phptools/php-5.6.23/ext/bcmath -I/usr/local/php/include/php -I/usr/local/php/include/php/main -I/usr/local/php/include/php/TSRM -I/usr/local/php/include/php/Zend -I/usr/local/php/include/php/ext -I/usr/local/php/include/php/ext/date/lib -DHAVE_CONFIG_H -g -O2 -c /home/tools/phptools/php-5.6.23/ext/bcmath/bcmath.c -fPIC -DPIC -o .libs/bcmath.o
- ... ...
- ----------------------------------------------------------------------
- Libraries have been installed in:
- /home/tools/phptools/php-5.6.23/ext/bcmath/modules
- If you ever happen to want to link against installed libraries
- in a given directory, LIBDIR, you must either use libtool, and
- specify the full pathname of the library, or use the `-LLIBDIR'
- flag during linking and do at least one of the following:
- - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
- during execution
- - add LIBDIR to the `LD_RUN_PATH' environment variable
- during linking
- - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
- - have your system administrator add LIBDIR to `/etc/ld.so.conf'
- See any operating system documentation about shared libraries for
- more information, such as the ld(1) and ld.so(8) manual pages.
- ----------------------------------------------------------------------
- Build complete.
- Don't forget to run 'make test'.
- Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/
5.查询,php.ini中extension_dir配置的目录中已经有bcmath.so文件了。
[root@192 sbin]# ll /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/
总用量 3984
-rwxr-xr-x. 1 root root 382568 10月 22 17:57 bcmath.so
6.在Dynamic Extensions配置块下添加一行extension=bcmath.so。
7.重启php服务即可。
