[Freeswitch-dev] Requirements to get actual UUIDs?

[Michael Giagnocavo]

What bothers me is that libuuid is found, uuid_generate is found. uuid_generate works properly. (Wrote a tiny app, include uuid/uuid.h, compile with -luuid; output is great). The output I am seeing, IIRC, is the result of APR not using libuuid, and using its own hokey timestamp based system.

Everything depends on libuuid:

yum erase libuuid
...
---> Package kernel.x86_64 0:2.6.32-220.el6 will be erased
...
Remove      147 Package(s)
Installed size: 731 M
Is this ok [y/N]: 

I removed libuuid-devel, re-installed e2fsprogs-devel, same problem. (uuid.h is detected, but not uuid_create or generated - output is still bad.)

I remember solving this a long time ago (on CentOS 5.2 or so), but I coulda sworn it was by installing e2fsprogs. Now that doesn't seem to work :\, and nor does libuuid-devel. If only there was A Portable Runtime to solve these kinds of things...
