  5. ... ...
  6. ----------------------------------------------------------------------
  7. Libraries have been installed in:
  8. /home/tools/phptools/php-5.6.23/ext/bcmath/modules
  9. If you ever happen to want to link against installed libraries
  10. in a given directory, LIBDIR, you must either use libtool, and
  11. specify the full pathname of the library, or use the `-LLIBDIR'
  12. flag during linking and do at least one of the following:
  13. - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
  14. during execution
  15. - add LIBDIR to the `LD_RUN_PATH' environment variable
  16. during linking
  17. - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
  18. - have your system administrator add LIBDIR to `/etc/ld.so.conf'
  19. See any operating system documentation about shared libraries for
  20. more information, such as the ld(1) and ld.so(8) manual pages.
  21. ----------------------------------------------------------------------
  22. Build complete.
  23. Don't forget to run 'make test'.
  24. 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。
