Will be addressed in 6.2.0-2

The gdb shows libcouchbaseembed.so load OK but init fails:

PluginDll::init (this=0x2082000, pluginCtx=0x7ffff7dd6900)

I use "dlerror" print dlsym error ((EclPluginDefinition) GetSharedProcedure(h,"getECLPluginDefinition")):

$1 = 0x165dfb0 "/opt/HPCCSystems/plugins/libcouchbaseembed.so: undefined symbol: getECLPluginDefinition"

nm shows "getECLPluginDefinitionP24ECLPluginDefinitionBlock" instead of just getECLPluginDefinition
nm /opt/HPCCSystems/plugins/libcouchbaseembed.so | grep getECLPluginDefinition
000000000002be66 T _Z22getECLPluginDefinitionP24ECLPluginDefinitionBlock

Add "extern C" will resolve the problem

couchbase entry in .gitmodule need update to plugins/couchbase/libcouchbase otherwise the submodule of couchbase is not even fetched with new Jenkins 2.8

README.md of couchbase tells user to install couchbase thorugh ubuntu apt-get. Is it correct?

I will build debug version platform and trace it
