Linking a static foo.a library directly into an AOLserver module's bar.so can definitely be useful at times, rather than using the foo.so at run time. (I remember once doing so to work around some weird problem with particular OpenSSL versions.) This isn't specific to AOLserver at all though, it is general C library hackery. There are all sorts of ways to tell different linkers what you want, too. For example, the Gnu linker accepts a '--version-script=' arg giving you complete control over what functions are exported vs. kept private within the *.so, which CAN be very useful in fixing name collisions. On Linux, I've told gcc to tell Gnu ld that I want to use that feature with: -Wl,--version-script=vis.map Then there's -Wl,-Bstatic and -Wl,-Bdynamic to control which libraries you link in statically vs. dynamically, etc. Lots of knobs. Again, nothing specific to AOLserver, this is just the fun of C programming, object file linking, ELF libraries, etc. Other platforms, like MS Windows, no doubt have their own esotericisms. -- Andrew Piskorski <[EMAIL PROTECTED]> http://www.piskorski.com/ -- AOLserver - http://www.aolserver.com/ To Remove yourself from this list, simply send an email to <[EMAIL PROTECTED]> with the body of "SIGNOFF AOLSERVER" in the email message.
