How to switch to GCC44

I'm using osx Lion and I installed Gcc44 through macport.

I also selected that version by means of the command

sudo port select gcc mp-gcc44

Now it is the active version, as rep开发者_如何学JAVAorted by the command

sudo port select gcc

However when I try to install other ports, macport still use the version 4.2 (I think the apple one).

How can I fix it? Thanks

The policy of the MacPorts project is for a port to use the default Apple-supplied compiler for a particular release unless there is some demonstrated reason why that port needs something different. Often those ports will have variants that allow a different MacPorts-provided compiler to be used. For example, you can search for ports that have a gcc44 variant. So, if you wanted to install the gcc44 variant of atlas, you would specify:

port install atlas +gcc44

That only works for ports that have defined variants. If you wanted to override the MacPorts defaults for a particular port, you could modify its ports file. The MacPorts guide documents the fields and their values, for instance, here. In general, though, you should stick to the defaults used in the MacPorts port file for a port.
