Re: [Fink-devel] Prebinding

[Carsten Klapp]

Hi,
There's a lot of work involved to build all of fink's dylib libraries as prebound, it probably won't happen any time soon.

However, any program which depends only on Apple-supplied dylibs can easily be built prebound using the -prebind flag in CFLAGS and LDFLAGS.

Some packages already do build prebound executables, take a look at these info files to see how it's done:
ccache, qtplay, antiword, fwipe, tidy (there's a few more but this should give you an idea).

To see whether your executable is a candidate for prebinding, run otool to see whether any libs from /sw are involved. If so, you're unfortunately out of luck.

% otool -L /sw/bin/antiword
/sw/bin/antiword:
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 62.0.0)

Once you think you managed to build a prebound executable, to confirm that it really is prebound run redo_prebinding on it. If there are any error messages then the binary was not prebound, so make sure you used -prebind in CFLAGS and if linking is done then in LDFLAGS too.

% sudo redo_prebinding /sw/bin/antiword
