How to identify Boost libraries which support eVC++ compiler
Hi, I'm trying to use Boost libraries with eMbedded Visual C++ 4.0 compiler (Windows CE applications development). I'd like to catalogue as much as possible Boost libraries which can be used with eVC++ 4.0 compiler. Currently, I can use smart pointers successfully. I also tried to use boost\date_time libraries and I found most of them can not be used with eVC++. I got "unknown CE compiler" error message. So, I suppose I will get that message in most cases. As I revealed there is a compiler detection mechanism in file boost\config\compiler\visualc.hpp but I couldn't find out how exactly it is used. I'd like to identify all Boost libraries which can not be used with eVC++. Could anyone give me a few hints about how to start such identification? Are there any macro definitions or can I expect that visualc.hpp can help me in this task? Thank in advance for all comments Best regards -- Mateusz Łoskot http://mateusz.loskot.net

I've been told that vs2005 supercedes eVC++4.0. since 4.0 is built on 6.0 technology which will (hopefully) be supported by boost only a little while longer wouldn't it be better to upgrade your compiler?

Yes, it does. But I was a little confused if this compiler for mobile devices is really updated and more standard conformant. Unlike in eVC++ and VC++ 7.1 wich are separated compiler packages for devices and desktop, VC++ 8.0 combines all compilers in one package. So, it wasn't clear if the update applies to all compilers or to the compiler for desktop Windows. I made a little investigation and I've learned that compiler for devices is also updated. Here is what explanation from MSDN: "Because the device compilers are based on the desktop computer VC compiler, examining the differences between the desktop computer VC 6.0 compiler and 8.0 compiler provides a good approximation about the changes between the eMbedded Visual C++ device compilers and the Visual Studio 2005 device compilers." Note: it still seems to be a lack of complete STL and C Run-Time implementations for Windows CE. So, I prefer STLport as STL implementation.
Since 4.0 is built on 6.0 technology which will (hopefully) be supported by boost only a little while longer wouldn't it be better to upgrade your compiler?
Yes, I'm going to buy VS2005 but I can't exactly say when. In the meantime I'd like to try to use Boost with eVC++ 4.0 and to catalogue libraries working with eVC++ 4.0. Best regards -- Mateusz Łoskot http://mateusz.loskot.net

have you tried the free VC++2005 express first link at http://www.thefreecountry.com/compilers/cpp.shtml don't forget to get the SDK

Yup! But VC++ Express edition does not support mobile devices development, unfortunately: http://msdn.microsoft.com/vstudio/products/compare/ Cheers -- Mateusz Łoskot http://mateusz.loskot.net

I suspect there was a bug in visualc.hpp that causes that #error to be generated in almost all cases with eVC++ (it's been fixed in cvs), so try commenting out the offending #error. After that if it compiles then it'll likely work (but try running a test program or two to make sure). Unfortunately we've never had anyone run the tests regularly on embedded platforms so your mileage may vary: so any feedback will be gratefully received! John.

Thank you for your suggestion. Indeed, it solved the problem. I commented line 131 in the file boost/config/compiler/visualc.hpp

Unfortunately, uncommenting that check solved the problem but partially. As my next testes, I tried to use Boost.Any and I see there are compilere related checks still present. When I include the any.hpp #include <boost/any.hpp> and I'm getting this error message (I have to confess that it's hard for me to decipher it :-)) c:\boost\include\boost-1_33_1\boost\mpl\aux_\yes_no.hpp(42) : error C2265: '<Unknown>' : reference to a zero-sized array is illegal c:\boost\include\boost-1_33_1\boost\mpl\aux_\yes_no.hpp(47) : see reference to class template instantiation 'boost::mpl::aux::weighted_tag<n>' being compiled c:\boost\include\boost-1_33_1\boost\type_traits\broken_compiler_spec.hpp(23) : fatal error C1506: unrecoverable block scoping error The message above relates to the following check of compiler: #if !BOOST_WORKAROUND(BOOST_MSVC, == 1200) typedef char (&type)[n]; #else I'd not want to send every such message and asking what to do with it. I think it could be a little annoying, but may be the problem relates to the bug in boost/config/compiler/visualc.hpp you mentioned above. Second, I will try to investigate every such problem and find out if there is possible some workaround. Certainly, it may be sometimes impossible for me to find the solution because I'm a Boost newbie user, yet. May be you could suggest what path should I follow in this job? I mean, with what Boost libraries should I start first? Which libraries are supposed to be less incompatible with VC++6.0/eVC++4.0? Thank you in advance Best regards p.s. As I explained in my response to Victor A. Wagner's post I'm not able to move to VC++ 2005 so I'll stay with eVC++ 4.0 for now. -- Mateusz Łoskot http://mateusz.loskot.net

The message above relates to the following check of compiler:
#if !BOOST_WORKAROUND(BOOST_MSVC, == 1200) typedef char (&type)[n]; #else
This is a known issue: eVC++ bumps the version number up to 1201 or 1202 so a lot of version checks / workarounds don't work anymore. A large patch for this was added to mainline cvs, but it didn't make it in time for 1.33.1 (too big a patch) See http://lists.boost.org/Archives/boost/2005/07/90101.php John.

I understand it now. Would you recommend to use CVS HEAD or I better wait until the patch will be included in future release? Cheers -- Mateusz Łoskot http://mateusz.loskot.net

Might be a long wait ;-) Either use a snapshot of cvs, or apply the patch to 1.33.1 (it just changes some msvc specific workarounds, so in theory it shouldn't cause any breakages, though you never know). John.

I'll try fix it that way. Thank you very much for your assistance! -- Mateusz Łoskot http://mateusz.loskot.net

I'd like to report that I did clean build of Boost CVS HEAD checkouted today. Second, problems with broken compiler detection mechanism have disappeared. Third, boost::any works with eVC++ 4.0 SP4 well :-) Now, I'm going to test the rest of Boost libraries with eVC++ 4.0. Thanks again! -- Mateusz Łoskot http://mateusz.loskot.net
