The fact you have to do that link indicates a deeper issue; did you run the ldd line first, and can you post that output? I found this workaround with Google: http://www.google.com/#sclient=psy&hl=en&q=%22PHP+Startup:+Unable+to+load+dynamic+library+%27%2Fusr%2Flib64%2Fphp%2Fmodules%2Fmysql.so%27+-+libmysqlclient.so.15%3A+cannot+open+shared+object+file%3A+No+such+file+or+directory+in+Unknown+on+line+0%22&aq=f&aqi=&aql=&oq=&pbx=1&bav=on.1,or.&fp=8d0ed00102c914af (That's the full error message text PHP was spitting out). First hit (an old Fedora bug): https://bugzilla.redhat.com/show_bug.cgi?id=176353 This has the workaround, but this is caused by something else going on. In any case, glad that worked, but you really do need to dig a little deeper and see why it did what it did, as the underlying reason is going to come back and bite you otherwise.... -------------- next part -------------- A non-text attachment was scrubbed...
