One could argue that you could add Yet Another Option Flag to ld(1) separate from -l to specify the major number of the lib. Looking at NetBSD's ld(1) manual page, it looks like -m is free, and somewhat intuitive. Alternatively, you could take it a step further and use -V (not -v, in case someone thinks that means "make the linker verbose" :-) to trigger "library version". I.e. some programs might want a featureset found in a specific _minor_. The command like could be parsed such that a -V affected the next -l, so you could do: ld -o foo foo.o -V 12.2 -lc -V 0.1 -lutil ...etc. However, this begs the question of why ports (I'm assuming you mean 3rd party software) that you compile from source "require different versions of shared libraries". That seems ... rather broken. -------------------------------------------------------------------------- Jason R.
