"expected unqualified-id" error
by Mahmood Naderan 19 Apr '10

19 Apr '10

Hi, I have successfully build Boost, but when I want to "make" a program which uses Boost library, I get an error that points to one of Boost files. boost/mpl/aux_/numeric_op.hpp:250: error: expected unqualified-id before ‘:’ token Part of the code is: #if !defined(BOOST_MPL_CFG_MSVC_ETI_BUG) : AUX778076_OP_IMPL_NAME< typename AUX778076_OP_TAG_NAME<N1>::type , typename AUX778076_OP_TAG_NAME<N2>::type >::template apply<N1,N2>::type #else .... It is strange for me because, the libboost are created so why get another error in boost now? // Naderan *Mahmood;

[date_time] Formating a posix::time_duration
by Sebastian Karlsson 18 Apr '10

18 Apr '10

I have a racing time in miliseconds which I'd like to apply formatting to, I can't seem to get it to work using posix::time_duration and what I'd think is the appropriate time_facet ( it produces the same results as the default facet ). Looking at posix_time_io.hpp I see the following comment: "// todo fix to use facet -- place holder for now...", leading me to believe that there's perhaps no way to apply the formating strings to a time_duration yet? We want to present our times as MM:SS,FFF.

Or better, I have a class A (without setter methods) and a friend class A_builder that aims to create and initialize objects of A. That's all, A_builder uses the parser to read from streams and fill structures strictly related to A, using dedicated functions. Considering this, parser is part of a more complex software and I can't easy extract it from the software. > Is it "something like" or it's the exact input? It looks like you try > to parse "1"/"0" with qi::bool_. This is incorrect, because bool_ > expects "true"/"false", so use qi::int_ instead. Oops! I'm a stupid, qi::bool_ really wants "true"/"false" string? Ehm... Oooook! Maybe this is the problem, I'll try. Thanks a lot to all, Michele

[GIL] Premultiplications when using color_convert
by Eloi Du Bois 18 Apr '10

18 Apr '10

Hi all, I am working on rgba32f view that have alpha values of 0. I need to apply a color_convert but it drops the values because of the 0 alpha valued. How can I disable alpha premultiplication ? If impossible, it should be a good idea to give a choice on copy_and_convert & color_convert. code sample: rgb32f_pixel p1, p2; p1[0] = 1.0f; p1[3] = 0.0f; color_convert(p1, p2); assert(p1[0] == p2[0]); Thank you by advance, Eloi Du Bois.

Spirit.Qi : forfait !
by Michele Caini 17 Apr '10

17 Apr '10

Ok, nothing to do, I'm not able to write a working parser with Boost.Spirit!! I attach to this mail the original flex/bison based parser, that I wrote some years ago, and the one developed with Spirit. It seems that parsing doesn't start () but I don't understand why that happens, I've tryied several ways without success. Help me, please. I'm going crazy!! It's so simple, and so difficult at the same time... :-( Thanks in advance to all! Michele
