Re: [Boost-users] [Context] Errors compiling Boost.Log on OS X

Thanks for looking into this, much appreciated! Oliver, would you mind clarifying why 'multi-lib' needs to be built? I assume you're referring to the threading=multi, and by the way we haven't been using that when building the other boost binaries for our project. I think I figured out the problem, Boost.Context seems to require "address-model=64" to be in the b2 command, regardless of my settings in user-config.jam. Adding that and everything, including Boost.Log, built fine. For the records, this is how I'm building Boost.Log universal binaries for Max OS X 10.8.3: // in user-config.jam: using clang : osx : xcrun clang -arch i386 -arch x86_64 -stdlib=libc++ -std=c++11 ; ./boostrap.sh --with-libraries=log ./b2 -a -d+2 -q toolset=clang-osx link=static address-model=64 stage cheers, Rich On Mon, Apr 29, 2013 at 9:51 AM, Oliver Kowalke wrote:

I'm using Xcode 4.3.3, gcc 4.2.1, these commands:

./b2 variant=debug address-model=32 architecture=x86 link=static threading=multi libs/context/test ./b2 variant=debug address-model=32 architecture=x86 link=static threading=multi libs/context/example

Sorry, I should have been clearer in that I'm using clang with libc++ (current Xcode version, 4.6.2), as this is now standard on OS X and required by our software framework.

My situation is the opposite of yours: I can't yet upgrade.

I have the following in my user-config.jam:

using clang : osx : xcrun clang -stdlib=libc++ -std=c++11 ;

To just build context, I do:

./bootstrap.sh --with-libraries=context ./b2 -a toolset=clang-osx link=static threading=multi stage

With Xcode 4.3.3, the above produces warnings but no errors.

lang-darwin.compile.c++

bin.v2/libs/context/build/clang-darwin-osx/release/link-static/threading-multi/unsupported.o

...

libs/context/src/unsupported.cpp:7:2: error: "platform not supported" #error "platform not supported" ^ 1 error generated.

Unfortunately this source file tells me nothing about the conditions that lead to its being compiled. I see in libs/context/build/Jamfile.v2 the following:

alias asm_context_sources : unsupported.cpp ;

(the only reference I found to 'unsupported' in boost/context or libs/context). bjam is a black box to me. I must defer to those who do understand it.

seams that multi-lib should be build - AFAIK boost.build doesn't support it yet.
