[mapguide-internals] GCC 4.4 and Oem upgrade

[Trevor Wekel]

Hi everyone,

Rohit and I have started chatting about the GCC 4.4 upgrade http://trac.osgeo.org/mapguide/wiki/MapGuideRfc92.  From previous work, I know that we need to update some of our third party dependencies.  We have a couple of options for Linux:

1. Update the necessary Oem components in the vault
Advantages:
- No change to build system
- Consistent components for Linux and Windows
- We can patch Oem whenever we want

Disadvantages:
- Security patches are never up to date
- More code to maintain in our vault

2. Go native and use the distro libraries on Linux  
Advantages:
- Security patches always up to date
- Faster build downloads
- Easier Linux packaging
- It will force us to post our fixes back to the original projects and be a better open source citizen

Disadvantages:
- Components may not consistent between Windows/Linux or even different Linux distros
- Repository migration more difficult


Any preferences/thoughts?


Regards,
Trevor & Rohit
