[BuildTools] RE: [Coin-discuss] shared vs static libs

[Andreas Waechter]

Hi BuildToolers,

Matt brings up a few good points.

First of all, the documentation on the wiki is not up to date (and you can 
blame me for that, but I also only have some limited amount of time...). 
Neither project specific compilation flags (as we actually have them now), 
not project specific debug, verbosity etc flags are documented...

Also, the config.site example file is VERY short.  I thought that I 
actually put a better example in there, but I guess I didn't, sorry.

Laci, do you still have the one that we started on?  I guess I should do 
that now before I make a new BuildTools release.  (I fixed a few issues 
for AIX and Darwin).

Maybe the best is if I just bit into the bitter apple (does that translate 
from German...?!?) and update the config.site file to include some actual 
information and documentation.  After that, maybe someone else can update 
the Wiki....?

Cheers

Andreas

> Andreas, correct me if I'm wrong, but you always get static libraries with --enable-debug, right? I don't think it's possible to override this behavior. You typically want static libraries when debugging, but I think if you specify that only a particular library should be compiled with debugging, then the others will be built shared, right?
