This is a native libdl for OS4 which implements the following
functions:

void *dlopen(const char *,int);
void *dlsym(void *,const char *);
int dlclose(void *);
char *dlerror(void);

These are compatible with the Linux versions, and implemented
via a wrapper to elf.library.


INSTALLATION
============

Copy libdl.a to SDK:local/newlib/lib/
Copy dlfcn.h to SDK:local/newlib/include/

NB: There is a libdl.so included with OS4, you can use this
instead by additionally executing the following command:
makelink sdk:local/newlib/lib/libdl.so sobjs:libdl.so soft

I've included my libdl.so for comparison, but it is not
necessarily a drop-in replacement.


USAGE
=====

In your code, include dlfcn.h:
#include <dlfcn.h>

When compiling, you must link with the following arguments:
-ldl -lauto -use-dynld

To build shared objects, compile with -fPIC and link with -shared

The dlopen_passV0.0.1 directory contains an example of how to use
the library (this is an open source example of which I have only
modified the makefile)
