Macromedia has created a hot fix for C++ CFX support on newer versions of Linux. This hot fix also allows C++ CFXs to be compiled and work with ColdFusion MX 7.
You only need this update if you are migrating existing C++ CFXs and updating them. Existing CFXs that are not updated and recompiled should not require this hot fix. This hot fix is required if any of your C++ CFXs are updated and recompiled or you create new C++ CFXs. Once you add these files, all your CFXs must be recompiled.
Note: There is a similar hot fix for ColdFusion MX 6.1 Updater 1 that resolves this same issue and adds Verity support. There is no similar Verity issue in ColdFusion MX 7 and this hot fix does not impact Verity. The ColdFusion MX 6.1 hot fix can be found in TechNote 54fb8a44.
