dlcompat for Darwin
|
||||
=========================
|
||||
|
||||
This is dlcompat, a small library that emulates the dlopen()
|
||||
interface on top of Darwin's dyld API.
|
||||
|
||||
dlcompat allows loading a ".dylib" library (as long as the RTLD_LOCAL
|
||||
flag isn't passed to dlopen()). It can be configured to yield a warning
|
||||
when trying to close it (dynamic libraries cannot currently be unloaded).
|
||||
|
||||
It automatically searches for modules in several directories when no
|
||||
absolute path is specified and the module is not found in the current
|
||||
directory.
|
||||
|
||||
The paths searched are those specified in the environment variables
|
||||
LD_LIBRARY_PATH and DYLD_LIBRARY_PATH plus /lib, /usr/local/lib and
|
||||
/usr/lib or the path specified in the environment variable
|
||||
DYLD_FALLBACK_LIBRARY_PATH.
|
||||
|
||||
In the default install the behavior of dlsym is to automatically prepend
|
||||
an underscore to passed in symbol names, this allows easier porting of
|
||||
applications which were written specifically for ELF based lifeforms.
|
||||
|
||||
Installation
|
||||
--------------
|
||||
Type:
|
||||
./configure
|
||||
make
|
||||
sudo make install
|
||||
|
||||
This will compile the source file, generate both a static and shared
|
||||
library called libdl and install it into /usr/local/lib. The header
|
||||
file dlfcn.h will be installed in /usr/local/include.
|
||||
|
||||
If you want to place the files somewhere else, run
|
||||
|
||||
make clean
|
||||
./configure --prefix=<prefix>
|
||||
make
|
||||
sudo make install
|
||||
|
||||
where <prefix> is the hierarchy you want to install into, e.g. /usr
|
||||
for /usr/lib and /usr/include (_NOT_ recommended!).
|
||||
|
||||
To enable debugging output (useful for me), run
|
||||
|
||||
make clean
|
||||
./configure --enable-debug
|
||||
make
|
||||
sudo make install
|
||||
|
||||
If you want old dlcompat style behavior of not prepending the underscore
|
||||
on calls to dlsym then type:
|
||||
|
||||
make clean
|
||||
./configure --enable-fink
|
||||
make
|
||||
sudo make install
|
||||
|
||||
Usage
|
||||
-------
|
||||
Software that uses GNU autoconf will likely check for a library called
|
||||
libdl, that's why I named it that way. For software that doesn't find
|
||||
the library on its own, you must add a '-ldl' to the appropriate
|
||||
Makefile (or environment) variable, usually LIBS.
|
||||
|
||||
If you installed dlcompat into a directory other than /usr/local/lib,
|
||||
you must tell the compiler where to find it. Add '-L<prefix>/lib' to
|
||||
LDFLAGS (or CFLAGS) and '-I<prefix>/include' to CPPFLAGS (or CFLAGS).
|
||||
|
||||
Notes
|
||||
-----
|
||||
If you are writing new software and plan to have Mac OX X compatibility you
|
||||
should look at the dyld api's in /usr/include/mach-o/dyld.h, rather than
|
||||
using dlcompat, using the native api's is the supported method of loading
|
||||
dynamically on Mac OS X, if you want an small example, look at dlfcn_simple.c,
|
||||
which should help get you started.
|
||||
|
||||
Also note that the functions in dlcompat are not thread safe, and while it is not
|
||||
POSIX spec compliant, it is about as close to compliance as it is going to get though.
|
||||
|
||||
You can always get the latest version from opendarwin cvs:
|
||||
|
||||
cvs -d :pserver:anonymous@anoncvs.opendarwin.org:/cvs/od login
|
||||
cvs -z3 -d :pserver:anonymous@anoncvs.opendarwin.org:/cvs/od \
|
||||
co -d dlcompat proj/dlcompat
|
||||
|
||||
|
||||
It is hoped that this library will be useful, and as bug free as possible, if you find
|
||||
any bugs please let us know about them so they can be fixed.
|
||||
|
||||
Please send bug reports to Peter O'Gorman <ogorman@users.sourceforge.net>
|
||||
|
||||
Thanks.
