linking C libraries

[Yi]

We are trying to make a library of our own and are getting lots of
missing symbol errors. The missing symbols are functions from UCSC
libraries that are included from our library. The library compiles
fine, and the ar command succeeds. The problem is when you include
the library in a program and try to use one of its functions. Does
this sound like a common error?
Any hints where to look? makefile? .h file? .c file?

Thanks a lot

This is not topical here.
Please ask in a newsgroup where your compiler/linker is on topic.
<OT>
Your mentioning of ar suggests a Unix-like environment, so I guess
you compile and link using gcc. If that is the case, ask again in
gnu.gcc.help. Note that you have to link the libraries your library
depends on, too, and that the order of linking also plays a role.
</OT>
Apart from that: Without your posting the ar, compiler and linker call
and the errors/warnings, only very few people will be able and/or
willing to help you.


Cheers
Michael
