[Mingw-cross-env-list] Updating versions

[Peter Rockett]

Hi

Newbie question - but...

I have used MXE only once before - massively impressed! Great job, guys!

I now want to start a new Qt project which I want to cross-build but the 
MXE Qt package version is 4.8.1 whereas the latest version (which I have 
downloaded for Linux) is 5.0.1, a major version increment. (Also, gsl is 
1.14 as opposed to 1.15 but that's a minor issue. Quite a few other libs 
seem 'out-of-date'.)  My question: How do I upgrade to the latest 
version(s) of packages?

I did initially expect to find version numbers as literal constants in 
the *.mk files but I did find the post at 
http://lists.nongnu.org/archive/html/mingw-cross-env-list/2012-04/msg00052.html, 
most of which, I am afraid I didn't follow because it requires a great 
deal of familiarity with the project. In a sense, MXE seems a victim of 
its own success in that the large number of available packages are 
likely to make version updating a growing problem. Something somewhere 
is always going to be updated! (And I'm certainly not going to be so 
ignorant as to demand you get that package updated NOW!)

Given that I would prefer not to try to cross-build across different 
major versions of a library, is there a simple answer to the question of 
upgrading, even just for my local installation?
