[Opensim-dev] DllNotFoundException: lib64/libode-x86_64

[Jak Daniels]

Hi all,

I think that libraries for linux should always be built on the oldest 
but still supported (with security updates) distro... for example 
centos/Rhel 5.  They will always work on the newer distros as they 
always have a compat glibc. I don't see the advantage in building on the 
latest and greatest distro and effectively then excluding their use on 
older systems especially as many VPS offerings still only provide Centos 
5 and 6 and earlier Ubuntus. It's the same principle as jenkins building 
Opensim on Mono 2.10.8 as a base line minimum version to ensure 
compatibility. I remember we had this issue with Bulletsim.so not 
working on RHEl5 due to it being built on a new system. Why shouldn't it 
be possible to run Opensim on a linux system that is still receiving 
security updates from the vendor? There would be uproar if we couldn't 
run it on say Windows 7.
