UUID RFC 4122 Version 1
lazarus / 66-Unix

Hello,

External web service requires message GUIDs to be generated using RFC
4122 Version 1. I tried to use libuuid.pp (this module uses
libuuid.so.1 and uuid_generate_time) and macuuid.pp. According to the
service, both GUIDs are incompatible with RFC 4122 Version 1.

Do Lazarus, Free Pascal or Linux (.so-library with appropriate
procedure) have ways to generate rigorous RFC 4122 Version 1 GUID?
Sorry, if I posted in the wrong section.

Thank you in advance for your help.

I have found a shared library uuid-ossp.so inside postgresql-contrib
package that could have helped me. ldd uuid-ossp.so shows that all
dependencies are resolved. libossp-uuid.so.16 is present. nm -D uuid-
ossp.so shows a lot of undefined symbols: uuid_in, uuid_out, ... They
are also absent in libossp-uuid.so.16. So, LoadLibrary doesn't work
for uuid-ossp.so. What particular version of libossp-uuid.so.16 is
required for Postgresql shared library uuid-ossp.so to work?

Is uuid.pas in fpcsrc/packages/hash/src not working for you ?

Thank you very much. Seems, it is really RFC 4122 version 1. As soon
as I get an access to the web service, I'll check it.
