linking to serialization

[g-h-d]

Hi All, I use Mac OS X 10.6. After following the ./bootstrap.sh and bjam
install steps, I have directory like this:

~/Library/boost_library/boost_1_40_0/include
~/Library/boost_library/boost_1_40_0/lib/
libboost_serialization.a
libboost_serialization.dynlib

and have the include directory path to Project > Build > Search path >
Header Search Paths and and the lib directory path to Project > Build >
Search path > Library Search Paths.

In XCode I did Project > Add to project > libboost_serialization.a

Running under Debug generates this message:

I use the SDK 10.6, 64 bit Intel architecture, otherwise (32bit) I get a
compile, not a runtime error (probably normal because by default bjam
creates the libraries for 64 bit).

Even if I remove libboost_serialization.a from the project and put
libboost_serialization.dylib in its place, I get the same runtime error.

Some help would be appreciated.

I suspect this message means that you need to add
~/Library/boost_library/boost_1_40_0/lib/ to the runtime libraries path.

On command line, this can be done via the DYLD_LIBRARY_PATH variable,
e.g.

        set DYLD_LIBRARY_PATH=~/Library/boost_library/boost_1_40_0/lib/:$DYLD_LIBRARY_PATH

you might want to manually expand ~ to your home directory above -- I don't know
how OSX shell behaves here.

I also don't know how to do this in XCode -- I suggest you first try running the
binary on the command line, with the above variable setting, and if it works,
check the XCode manual for a comparable setting.

Thanks, but it hasn't worked. Note that I did replace ~ by it's expanded
version but $env does not show DYLD_LIBRARY_PATH : is it supposed to?


First, I don't see why it's looking for dyn library if I add
libboost_serialization.a to the project, not
libboost_serialization.dynlib (even if I reverse their roles I still get
the same linking error message as above).

I found this but have yet to make sense of it.

Yes, it is supposed to. You might want to also 'export DYLD_LIBRARY_PATH', but otherwise
I have no idea.

This I don't know. It is likely that some library you use still wants dynamic
serialization.

Thanks, export has worked, and ...

...I'm using a simple test case that only involves serialization and so
far no luck.

A simple question : how do I tell XCode to load a particular library? My
understanding was that a) I should specify the Linking Search Path in
the build settings and b) adding the desired library to the project (Add
to Project).

Perhaps I'm wrong about b). Could someone please confirm?

This is no longer an issue.

The problem in my case is that I in /usr/local I did $ ./bjam --prefix =
  ~/some path

by ommitting the prefix and copying bin.v2 to ~some/path things follow
there.

Actually there's no need to copy bin.v2 to a folder in ~. A small tip
I've learned is you can add a file from /usr/local to a project (Project
 > AddToProject) with Apple key + Shift + G
