RHL 6.2 compat libs for RHL 9?
 

Are there compatibility libraries for RHL 9 that will allow development and testing of applications born on RHL 6.2?

If not, by what method can I install old libraries (ca. RHL 6.2) that will allow development on RHL 9 without corrupting the existing gcc tools and libs?

I don't think that simply installing the older gcc and libs from RPMs will work, since they will probably try to occupy some of the same space, expecially symlinks and includes. I'm thinking I should get the source RPM's and modify the install dirs in the spec file so it will be totally separate. Then we could use env variables and Makefile directives to use the correct tools and libs. Has anyone done this? If so, please include "mucho" details in your response.

Background:

There is a project at my site where an application program (let's call it a game) was developed, tested, and released on an Intel platform under RHL 6.2. The developer team all want to use RHL 9 as their development platform, but are having issues with incompatible native libraries.

The target platform will remain Intel/RHL 6.2 for some time until it can be ported.

They will need to develop and test on RHL 9. If we can't do this, the development machines will have to be downgraded to RHL 6.2 or 7.3. RHL 7.3 appears to work, but we want the features offered in RHL 9.

Thanks for any tips you might offer.
