PHP Warning: PHP Startup: Invalid library (maybe not a PHP library) 'couchbase.so'

I am trying to setup php to connect to couchbase and I get the following

PHP Warning: PHP Startup: Invalid library (maybe not a PHP library) ‘couchbase.so

couchbase php extension was installed with:

pecl install couchbase

I’m on CENTOS 5 with php5.4.34

Hey dartasura,

Would you be able to explain how you are installing the library?

Cheers, Brett

Hi brett,

I have ssh access to my server i do:

pecl install couchbase

and i got this output:

Did not download optional dependencies: pecl/igbinary, use --alldeps to download automatically
pecl/couchbase can optionally use package “pecl/igbinary”

Libraries have been installed in:
/root/tmp/pear/pear-build-rootK1SmDj/couchbase-2.0.0/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’.

i got a Class ‘CouchbaseCluster’ not found.

If i check the php error_log i have this error

I also try to build the lib from source like that

Best regards

How are you specifying the couchbase binary to load?

Cheers, Brett

i thought the problem was couchbase but it’s doing that for all pecl extension i try to install.
I think i gonna close this thread but thanks for your help anyway

Best regards, dart

Ok i find why if someone have this problem one day it was because my autoconf version was to low

Glad you got it fixed. Thank you for posting your resolution!

Cheers, Brett
