I've tried with two versions: first, I downloaded and compiled latest
released Axisc/2 v. 1.3.0 from the http://ws.apache.org/axis2/c; after
seeing this error, I downloaded a "WSO2 Web Services Framework for
C++" from the http://wso2.org/projects/wsf/cpp, where, I hoped, given
that the name includes "for C++", the C++ problems would be solved.
This release, as I understand, includes Acis2/C version 1.2. The same
error (with the same text returned by dlerror(), after I added
logging of this) happens in both cases.
Thank you,
alex.
