Subject: Re: [OMPI users] Basic question on portability

Yes, you will have problems.

We did not formally introduce ABI compatibility until version 1.3.2. Meaning: your application compiled with 1.3.2 will successfully link/run against any 1.3.x version >= 1.3.2, and against any 1.4.x version.

v1.5 broke ABI with the v1.3/v1.4 series, but it will also be stable for the duration of the v1.5/v1.6 series.

We have no definite plans yet for v1.7, but it is likely that the ABI story will be the same there, too -- break from v1.5/v1.6 and stable for v1.7/v1.8.
