Hi Jeff, I looked into the developer list (which I am not subscribed to) and found your posting:
Using the latest portable_binary_archive from the vault with boost 1.34.1 on Mac XCode 3 I'm getting a linker duplicate symbol error: ...
It might be that the mac compiler is a bit more strict on multiple template instatiations or else. I suspect line 203 to cause your error,
From my (limited) experience instantiations seem to occur earlier as well.
so you could try to move the (entire) instatiation part into a separate file if you include portable_binary_oarchive.hpp multiple times. Also be sure that your compiler understands #pragma once or change to the traditional #ifndef guard.
// explicitly instantiate for this type of binary stream template class basic_binary_oarchive
;
Thanks for the tips. If we run into problems with the trunk version we'll look at this separation. For now we're up and running.
We have had no user on the mac side of life so you're lucky to be the first ;) If you do not succeed trying the suggestions above or need further information feel free to contact me directly or post to the user list.
The trunk version now works with Mac XCode 3 intel/ppc(boost_1_34_1) as I mentioned in my reply to Robert! I'll be moving us to 1.35 soon.
It is somewhat confusing to have two portable_binary_archives around (vault and trunk), so always specify which one you are referring to.
I thought I did: "Using the latest portable_binary_archive from the ***vault*** with boost 1.34.1 on Mac XCode 3 I'm getting a linker duplicate symbol error:" Thanks again for the help, Jeff
