In such a case, I guess I need some advisor/revisioner to look after the small Makefile for the port I wrote to push it into the ports collection. Because libxerces-c2 and libxerces-c3 seem to break the API, it is obviously a good advice haveing a new generation port.

Well, I just compare to xerces-c.so.27 or xerces-c.so.28 (xerces-c2-devel). Both libraries get installed according to the FreeBSD's library naming policy. I do not find any library that is apart from this naming policy in my boxes /usr/local/lib. Old xerces-c ports seem to have some kind of home-brewn build environment, so GNU autotools do not apply and it seems to be easier to come along with the naming policy which is introduced for FreeBSD's libraries. Usually, libNAME.so.VER with greatest VER symlinked to libNAME.so. How VER represented (it just a number, or more complicated like .N, .N.M., .N.M.K... -- depends on the ld.so implementation on the target system and usually should not bother you as software author (if you use Libtool, which is good in job of hiding differences between systems in that respect). Also, these .N[.M[.K]] represent the ABI version of library and has nothing with package version. Just in the case of Xerces, the NAME contains digits that looks like version (version of package). But indeed, the NAME in your case _is_ libxerces-c-3.1. I unable to say what ABI version VER is without building Xerces-C, or upstream authors decided to left it empty indeed, sorry. The new xerces-c 3.1.1 comes with a whole/complete autotools-environment. There is a
Renaming a shared library in the port-framework to match FreeBSD naming schemes?
Hello. Trying to do my first port and run into trouble. The software package (Xerces-c 3.1.1) comes with a full autotoll environment and so far building and installing works. But the libarary name is libxerces-c-3.1.so and I need to change this to respect the FreeBSD nameing schemes to libxerces-c.so.31. I'm looking for a way avoiding some post-install: stuff. Is it possible to manipulate the library name via some variables passed through the port-framework to the build-enviroment? Well, I'm very new to porting and this may seem to be a very easy task for experienced porters, so please excuse possible bothering ...

Inability to catch the libxerces-c-3.1.so by specifying -lxerces-c linker flag (and enforce you to specify -lxerces-c-3.1) is intended and desired effect. Please, don't touch the library name. Usually, authors change library name if want to ensure and express complete API and ABI break without any forward and backward compatibility. Like switch from Glib-1.x (libglib.so.x) to Glib-2.x (libglib-2.0.so.x). In both your (libxerces) and my (libglib) examples the authors desired to use interface generation numbers, but it just for aesthetics reasons, indeed the libraries could be renamed to any other arbitrary way (for example, libNewGlib.so and libEvenBetterXerces.so -- ideologically and technically there no differences). If you rename libxerces-c-3.1.so to libxerces-c.so.31, then all application that want and expect the old zero-generation API and link against '-llibxerces-c' will fail because will catch absolutely unexpected (by them) and incompatible libxerces-c-3.1 API. Applications that indeed want and expect libxerces-c-3.1 API, and therefore that links with '-llibxerces-c-3.1' will fail also. Just because there no more libxerces-c-3.1.so library -- it was renamed to unexpected name w/o good reasons. Conclusion: Please, don't touch library names! Well, maybe here is a misunderstanding. I'd like to come along with FreeBSD's library naming scheme when installing the library into /usr/local/lib. I thought manipulating the source-environment when compiling would be the least-efford way, but I see, maybe it would be easier to come along with a post-install: target by simply moving and making a symbolic link. If so, I need to detect by the framework what the lib vendor has choosen as thi lib name, to automate the proceed perfectly.
