lib expat version numbering

[public@…]

I am having some problems with the expat lib and I found some strange numbering

After compiling expat I try to have a look at the build output here:

/opt/local/var/macports/software/expat/2.0.1_1/opt/local/lib

As you see, it is version 2.0.1_1. However the folder output looks like

lrwxr-xr-x  1 root  admin      16  2 Okt  2010 libexpat.0.dylib -> libexpat.1.dylib
-rwxr-xr-x  2 root  admin  154336  2 Okt  2010 libexpat.1.5.2.dylib
lrwxr-xr-x  1 root  admin      20  2 Okt  2010 libexpat.1.dylib -> libexpat.1.5.2.dylib
-rw-r--r--  2 root  admin  184312  2 Okt  2010 libexpat.a
lrwxr-xr-x  1 root  admin      20  2 Okt  2010 libexpat.dylib -> libexpat.1.5.2.dylib
-rwxr-xr-x  2 root  admin     828  2 Okt  2010 libexpat.la

I am concerned if my problems linking against libexpat might be because of the numbering. Normally I would expect too get the library compiled as:

libexpat.2.0.1.dylib

instead of

libexpat.1.5.2.dylib

Is the current output the right one?

Please describe them.

and I found some strange numbering

Everything you described is completely normal. It is not unusual (in fact it is the norm) for library version numbers to follow different schedule than program version numbers.
