[Mapserver-users] php_mapscript from cvs undefined symbol: curl_multi_info_read ?

[Vincent Schut]

TM,

as you mentioned in your ldd output that your libcurl.so.2 is in /usr/lib, 
this might be an old remnant of an *binary installation* of libcurl you did 
and forgot to undo before you compiled curl yourself. If you compile curl and 
do not specify the prefix, it will install in /usr/local/lib, not in 
/usr/lib. Probably you (or your automagic installer) have installed an older 
(and incompatible) version of libcurl long ago which is still there. Usually 
/usr/lib has preference over /usr/local/lib for the dynamic linker, so the 
old version will be found and used, resulting in an error.
To check if this is true: is there also a libcurl.so.2 in /usr/local/lib? What 
is the date of the libcurl.so.2 in /usr/lib (probably pretty old, not the 
date you compiled curl).
What should you do if this is the case: properly remove the old curl (rpm, 
apt-get, yast, whatever your linux distro uses...) or manually delete the 
libcurl* files and the files belonging to it in /usr/include (!!!).
Eventually recompile and install curl to make sure it gets installed right in 
place.
That should do the trick.

Regards,
Vincent Schut.
