using clang to build wxWidgets on Linux

[Alec Ross]

I've just attempted to build wxWidgets w/ clang on Linux, using, from
the build directory

sudo CC=clang ../configure; sudo make

Looking at the console output from configure I could see that clang was
being accepted and used; and I _thought_ that I saw this too in the
first few lines from make. However make seemed to be mostly, if not
completely, compiling with command lines invoking g++.

So, some questions:

1) is there some simple and acceptable way to build using clang? (e.g.
repeat the setting of CC for the make command?)

2) The possibility that clang might build faster than g++ - specifically
for a Raspberry Pi Rasbian OS - was the motivation for this experiment.
(Tho' clang 3.0 is currently the latest available from the relevant
repos. I'd hope that later versions of clang would compile and build
faster.) Does anyone have any experience or thoughts on this?

3) And other advice/comments?

TIA,

Alec

You should set CXX to change C++ compiler, not [only] CC which is the C
compiler.

Also, you really shouldn't run neither configure nor make under sudo, who
knows what kind of horrible "rm -rf /"-like bugs there could be in our
build process.
