以下安裝mongo-php-driver 也許會遇到

PHP Warning:? PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/mongodb.so' - /usr/lib64/php/modules/mongodb.so: undefined symbol: bson_decimal128_from_string in Unknown on line 0

問題。

遇到如下問題：

解決問題使用如下：

libtool: install: cp ./.libs/mongodb.so /home/.../mongo-php-driver/modules/mongodb.so

----------------------------------------------------------------------

Libraries have been installed in:

?? /home/.../mongo-php-driver/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’.

[root@www mongo-php-driver]# make install?? ? ? ? ??? ? ? ? ?

[root@www mongo-php-driver]# cat /etc/php.d/mongo.ini??? ? ? ? ??? ? ? ? ?

extension=mongodb.so

apache error_log里出現：

PHP Warning:? PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/mongodb.so' - /usr/lib64/php/modules/mongodb.so: undefined symbol: bson_decimal128_from_string in Unknown on line 0

這個c-driver的問題，mongo也還沒暫時沒有解決，鏈接如下：https://jira.mongodb.org/browse/CDRIVER-1173

描述如下：

Since bson_decimal128_from_string () requires a null terminated string, the BSON to JSON conversion for bson_decimal128_t allocates a new string+1 since the input isn't null terminated.

We should be able to avoid that extra malloc, either though stack allocation or passing the length to the bson_decimal128_from_string () function.

---------------------------------------------------------------------------------------

所以變更驅動，使用PECL驅動

#?tar zxvf mongo-1.6.13.tgz?? ? ? ? ??? ? ? ? ?
