[GIL] color_converted_view usage problem
by Marc-Antoine ARNAUD 02 Jun '12

02 Jun '12

Hi guys, I currently working on TuttleOFX projet, and using Boost GIL to perform some image process. I wan't using color_converted_view to process clamping values on a view, witth a specific ColorConvert (CC) functor. But with the actual code [ https://github.com/tuttleofx/TuttleOFX/blob/master/libraries/terry/src/terr…] , the pixel_clamp contructor was corretly called, but our functor (void operator()( const SPixel& src, DPixel& dst ) const) wasn't. Does someone have the same bug ? Are they more documentation anywhere on this function ( I'm refering on this link: http://stlab.adobe.com/gil/html/group___image_view_transformations_color_co… ) Thanks, -- Marc-Antoine

Add a compile flag to bjam?
by Neal Becker 01 Jun '12

Using bjam, is there an easy way (preferably on the command line) to add a flag or 2 to the compile (using gcc)? I'd like to add an optimization or 2.

[Asio] Compiling DLL project with stdcall calling convention
by Da-Huntha 01 Jun '12

01 Jun '12

I'm using Boost.Asio in a windows DLL project and had to change the calling convention to stdcall, now when I try to build I get the following build errors: 1>C:\boost_1_49_0\boost/asio/ detail/impl/signal_set_service.ipp(74): error C2664: 'signal' : cannot convert parameter 2 from 'void (__stdcall *)(int)' to 'void (__cdecl *)(int)' 1> None of the functions with this name in scope match the target type 1>C:\boost_1_49_0\boost/asio/detail/impl/signal_set_service.ipp(247): error C2664: 'signal' : cannot convert parameter 2 from 'void (__stdcall *)(int)' to 'void (__cdecl *)(int)' 1> None of the functions with this name in scope match the target type I'm using MSVC10. Can anyone help me with these errors? I have no idea what to do with them.

problem with boost compilation
by Ohad Barta 01 Jun '12

01 Jun '12

Hi I installed and compiled boost for my project a long time ago, however now I fail to repeat on this success on another computer. I use only the serialization library, therefore the folder that my project linker includes in order to work properly is: C:\boost_1_47_0\boost_1_47_0\bin.v2\libs\serialization\build\msvc-10.0\release(or debug...)\address-model-64\link-static\threading-multi what is the corresponding cmd compilation command? I tried to specify all the corresponding flags but for some reason it doesn't work,(for example- despite using the flag --address-model=64, the folder "address-model-64" wasn't constructed in my folders hierarchy tree, so I guess that this flag was ignored) Thanks in advance!

asio ssl handshake error
by Lloyd 01 Jun '12

01 Jun '12

Hi, We are using SSL for secure communication. In this both the parties verify each other (ctx.set_verify_mode(boost::asio::ssl::context::verify_peer|boost::asio::ssl::context::verify_fail_if_no_peer_cert);). Both the communicating parties uses self signed certificates. Both client and server loads the each others public key for peer verification, for that we use the call ctx.load_verify_file(). At the client side when we call "load_verify_file()" only once with the other parties public key it works perfectly. If we load one more public key of some other application again using "load_verify_file()" the peer authentication fails. So what I understood is "load_verify_file()" loads only one latest certificate, but the documentation says it can be used for loading one or more CA files. To solve this, I also merged the two certificates into one file and tried loading it. If the valid certificate is in the second position in the file the verification is performed successfully. Otherwise it fails!! What could be the reason, is there any method available for peer authentication? Thanks, Lloyd
