[context] Providing template class enumerate in context.hpp
Hi all, I am trying to use the newly accepted boost.context and I am wondering why something as useful as the template enumerate is not diretly given when including "context.hpp" and not even in a separate header. Since it's in the doc it would be a good addition IMHO. Thanks, Julien PS: the link to boost.context doc is broken and the git repos seems to have moved.
Hi Julien,

you referring to the example 'enumerate'?! it was intendet to demonstrate the usage of boost.context. maybe I'll provide an separate lib with the 'enumerate' stuff if appropriate.

Yes I am. Having played a tiny bit with C#, it's the first thing I wanted to try. Not related, I have problems linking with boost.context on MSVC 10, 32 bits when trying to compile the example folder using bjam :
test_context.obj : error LNK2019: unresolved external symbol _boost_fcontext_jum p referenced in function "public: int __thiscall boost::contexts::detail::contex t_base::suspend(int)" ( ?suspend@context_base@detail@contexts@boost@@QAEHH@Z) libboost_context-vc100-mt-gd-1_49.lib(fcontext.obj) : error LNK2001: unresolved external symbol _boost_fcontext_jump
Finally, have you considered adding auto linking ? I guess that can be done easily using the following code in context.hpp: #define BOOST_LIB_NAME "context" #include <boost/config/auto_link.hpp> Thanks for your efforts, Julien

I have tried with boost trunk, the result is the same, nothing links, (except echo_client.exe). After analysis of the logs I think the problem is that the build system can't detect my system properties properly: next alternative: required properties: <abi>ms <address-model>32 <architecture>x86 <binary-format>pe <target-os>windows not matched My system may have two catches: first the OS is in chinese and I have a 32 bit OS with a 64 bit CPU. I am using MSVC 10 express edition. I'll try to dig in the build system to see if I can find how the matching is done. Julien

unfortunately boost.build doesn't set values for the required build properties (only for default-properties). I'll would try following: bjam toolset=msvc-10.0 architecture=x86 instruction-set=i386 address-model=32 Oliver -- Empfehlen Sie GMX DSL Ihren Freunden und Bekannten und wir belohnen Sie mit bis zu 50,- Euro! https://freundschaftswerbung.gmx.de

Yep, I had the same problem when trying to use the Context library and I solved it by using a command line similar to the above. Only difference is that I found I didn't need to specify the instruction set, only the architecture and address-model.

the command line option are described at http://ok73.ok.funpic.de/boost/libs/context/doc/html/context/installtion.htm... the issue results from a limitation of boost.build (default/non-default properties) as already described Oliver
Hi
the command line option are described at http://ok73.ok.funpic.de/** boost/libs/context/doc/html/**context/installtion.html<http://ok73.ok.funpic.de/boost/libs/context/doc/html/context/installtion.html> the issue results from a limitation of boost.build (default/non-default properties) as already described
First, thanks, that worked for me. One small issue: the link above doesn't work for me (connection error). Is there any plan to upgrade boost.build to change/repair that ? A quick search inthe mail archive didn't bring significant results on that topic. This is a much required change IMHO. Julien

Until the boost.build developers do provide the required boost.build props (like architecture, address-modell, ... as default boost.build properties) you are forced to specify them on bjam command line.

Pending a real fix, I just committed a fix to improve the error message. In Christ, Steven Watanabe

Yes I am. Having played a tiny bit with C#, it's the first thing I wanted to try.
FYI, I've started a project here: https://github.com/jamboree/boost.enumerator/tree/header-only But it lacks docs and examples, you can refer to only the test for now...

I'll have a look, thanks. Like this it looks interesting because the first thing I did was implement an iterator over "enumerator" and it seems you provide it out of the box. Julien

a iterator is copyable - but a context is not so take care that you prevent copy it. Oliver
Hi again, you referring to the example 'enumerate'?! it was intendet to demonstrate
the usage of boost.context. maybe I'll provide an separate lib with the 'enumerate' stuff if appropriate.
I think I have found a bug in the sample. In the destructor, I get a "calling virtual function exception" for Enumerator that are never started. The following code seems to work:
if (started_) if ( do_unwind_ && ! ctx_.is_complete() ) ctx_.unwind_stack();
