[cctbxbb] Module versioning (was Re: Debian Package)

[Jeffrey Van Voorst]

Possibly off topic, but I had issues with libtool and Mac OS X. Shared 
libraries need to be specified vi the -L/path/to/library/dir --libname 
linker flags when using libtool on Mac OS X.  For what its worth, I 
wrote my own pkgconfig files with the necessary -L and --libname linker 
flags (and CFLAGS).  This appears to work fine on Mac OS X, debian, Suse 
Enterprise Linux, and Gentoo.

The reasons are:
*) Mac OS X uses .dylib for shared libs; libtool ignores *.dylib; and 
specifying .dylibs is not good in that it makes the Mac OS X setup 
differ from that of Linux distributions
*) Mac OS X does not use *.so files (as far as I know)

On another note, are there regression tests (+ documentation) for the 
shared libraries?  If so, it should be fairly easy to setup an automatic 
method to generate pkgconfig files + simple tests to make sure the 
linking works.  On the other hand, I am assuming Scons is supposed to 
replace much or all of the standard autotools buildchain, and I don't 
know if Scons has an equivalent to pkgconfig files.
