PHP没有找到DB2扩展

Question

I have a vagrant box set up for development. It has been running fine for months, but I recently ran vagrant box update since it'd been nagging me to update, and naturally it's now broken.

The problem is with PHP startup. It can't find the DB2 so file:

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php5/20131226/ibm_db2.so' - libdb2.so.1: cannot open shared object file: No such file or directory in Unknown on line 0

However, the file is there:

~$ sudo find / -name '*db2.so'
/usr/lib/php5/20131226/ibm_db2.so

Any idea what's up with this error?

Answer 1

When I updated my vagrant box the PHP extension was installed correctly but could no longer find the DB2 headers. I had to sudo pecl uninstall ibm_db2 then follow the instructions here to download and install the DB2 headers. Finally I reinstalled the pecl extension using sudo pecl install ibm_db2 and I was back in business.
