ColdFusion MX 7: Native CFX support on LinuxProducts affected
Issue
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.
Reason
Without these updated files, newly compiled C++ CFX files will cause a JVM crash with an error similar to:
Unexpected Signal : 11 occurred at PC=0x3FC63909 Function=(null)+0x3FC63909 Library=/opt/coldfusionmx7/runtime/jre//lib/i386/server/libjvm.so
Solution
- Stop ColdFusion.
- Backup and then remove the following two shareable libraries from cf_root/lib:
- libporting.so
- libCFXNeo.so
- Replace the libraries with the files in cf701_61543.zip
- Restart ColdFusion.
With these replacement libraries, all C++ CFXs must be recompiled and linked with the current version ofglibc. Existing (legacy) C++ CFXs will not run.
With the original libraries, existing C++ CFXs that were compiled and linked with earlier versions of glibc will run without recompilation.
