Hi Andrew, Many thanks for the feedback. I've already been down the MacPorts route, but it didn't seem to help and a colleague suggested I'd be better off taking the "raw" approach and building from source before posting to this list. I'll have another go at fiddling with the architecture parameters in XCode, but I've tried this before and only succeeded in generating more errors rather than fewer:) If you happen to have a burst of inspiration as to the details of your solution, I'd really appreciate hearing about it. Best wishes.

I initially installed boost via MacPorts which I have found the easiest way to keep things working and up to date. https://www.macports.org/install.php I'm using Xcode 4.6.1. I use CMake to generate my xcodeproj, but hopefully some of this should still apply. Then, to resolve some of these other issues with targets but I believe I needed to change some of the build settings on the xcodeproj. If you go to the little folder icon aka Project Navigator > Project Build settings (on the right) > Architectures + Base SDK + Supported Platforms + Valid Architecture. I have found that messing with some of those settings gets things to work again. The other thing I may have done is regenerated my Xcode project in CMake because the generated targets were out of date, though that may or may not be helpful to you. I'm sorry I don't have a more straightforward answer, but I never actually wrote the steps down and I figure that some suggestions are better than none and may lead you in the right direction.

Hi,

I have an XCode c++ project that uses the static serialisation library (as well as FileSystem, IOStream and System). The project started out on XCode 3.6 on Mac OSX 10.6, where it successfully built and ran using Boost 1_49_0, built against Apple's 10.6 SDK.

However, I needed to use the XCode debugger to track down some run-time issues and found I couldn't access the debugger on this version of XCode (I'm blind and have to use the VoiceOver utility to gain access to my Mac). Having taken advice, I upgraded to Mac OSX 10.8, SDK 10.8 and XCode 4.6, which solves my debugging issue.

Unfortunately, my project no longer links correctly. The linker complains that it can't find symbols for my architecture (x86_64) - the messages are in the the form:

"boost::archive::basic_xml_iarchiveboost::archive::xml_wiarchive::lo ad_sta rt(char const*)", referenced from:

"boost::archive::basic_xml_iarchiveboost::archive::xml_wiarchive::lo ad_ove rride(boost::archive::version_type&, int)", referenced from:

"boost::archive::basic_xml_iarchiveboost::archive::xml_wiarchive::lo ad_ove rride(boost::archive::class_id_type&, int)", referenced from:

(I've truncated the output here for brevity). I get no linker errors for any of the other Boost binaries - it's only the serialisation library that creates a problem.

The project is configured to compile with the llvmgcc42 compiler, as it also uses the wxWidgets libraries, which don't support compilation using clang.

Boost versions tried:

1_50_0, 1_52_0 and 1_53_0.

Boost build options tried:

1 - Default (no options specified) - this worked on Mac OSX 10.6, Snow Leopard.

2 - As follows:

macosx-version=10.3 macosx-version-min=10.6 architecture=combined threading=multi link=static address-model=32_64

3 - As follows:

architecture=combined address-model=32_64

I'm a novice using Boost and the Mac, so would appreciate any suggestions as to how I can resolve this issue.

Hi Mathias, Not sure what the netiquette is on this list for providing large amounts of output, so I'll play safe and post a link to the full build output and files containing what Boost build options I've tried and my XCode project configuration. https://dl.dropbox.com/u/29578720/Boost%20serialisation%20and%20XCode.zip My naive interpretation would be that, if my binaries were built using the wrong options, I'd expect all of them to throw up errors, since the project also uses FileSystem, IOStream and System, but this isn't the case.

You're probably linking against a binary built with different settings that the ones you're using.

Hi, I built Boost with the Darwin toolset, so that uses GCC (how can I check which linker is being used by the Boost build system?). My application project is linking using libc++. Assuming I've got a linker mismatch, how can I either get Boost to link using libc++, or get XCode to link using stdlibc? Best wishes.

[...] Hi, This is really just a guess, but: Did you build Boost using clang with libc++? If so, and if you are building your project with gcc and stdlibc++, that could be the source of the problem. IIRC, libc++ broke the ABI compatibility with stdlibc++. To turn potential runtime errors into link-time errors, they used inline namespaces. For example, symbols inside the std namespace with libc++ are of the form std::__1::symbol while with stdlibc++ they are of the form std::symbol When linking with a library built with a different runtime, the linker will fail to find the symbols, turning a nasty runtime error into a link failure. If I were you, I would look at the symbols exported by Boost. If they don't match those referenced by your project, that could be it.

OK, I found an article suggesting I set an XCode linker flag: -Lstdlibc++ It doesn't help, so I'll try your suggestion and attempt a Boost rebuild using libc++. Best wishes.

You'd need to pass -stdlib=libc++ to clang when compiling and linking.

or get XCode to link using stdlibc?

There must be some XCode option to pass -stdlib=libstdc++ to the compiler, which tells it to use libstdc++. _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost

I'll take your word for it. My main issue here is that I'm a complete novice on Mac, XCode and Boost, so it feels like crossing Europe without a map. I'm trying hard to read articles and try the suggestions I find, but don't have the experience to evaluate the credibility of the articles before giving them a whirl. I tried the flag with -l and -L, just in case it was case-sensitive (it appears not, but you may tell me different). Best wishes.

Really? Despite widespread misunderstanding (including in ) the library is called libstdc++ not stdlibc++ and lives in a file called libstdc++.so, whereas I believe libc++ lives in a file called libc++.so, so I don't see how just setting a directory with -L can change anything. _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost

Many thanks for the explanation. In your example of the lower-case version (i.e. the one I should be using) you have a space before the value. In the articles I've come across so far there's been no space - which form is correct, or is the space character seen as white space and ignored? Best wishes.

"-L dir" adds the directory dir to the linker's search path, "-l x" tells it to link to a library libx.dylib or libx.a, so they are completely different. _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost

Many thanks for the explanation. In your example of the lower-case version (i.e. the one I should be using) you have a space before the value. In the articles I've come across so far there's been no space - which form is correct, or is the space character seen as white space and ignored?

"-l x" and "-lx" are equivalent. _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost

Well, Having the correct files included in the project sure makes a difference:) My only excuse is that my speech output on the Mac mangled this file name, so I hadn't recognised it for what it was (this is lame). I'll do some more experimenting to see if reverting my linker changes affects the result, but the project now builds. Many thanks to all who got me to this point. Best wishes.
