PGI compile problem with lanczos_sse2.hpp
by Brian Carnes 05 Oct '10

05 Oct '10

I am trying to link to a library that uses some code from boost. So far I have been able to build the code under gcc, intel and pathscale compilers. However, I get about 100 errors from this file under pgi (versions 7.1, 7.2 and 10.1) boost/boost/math/special_functions/detail/lanczos_sse2.hpp I have copied the first few error messages to the end of this email. My suspicion is that some settings are not correct for this compilation under PGI. I did check that the header files used by "lanczos_sse2.hpp" were present. I don't have any experience with the SSE/SSE2 optimizations. FYI, our build system uses bjam, so there is a Jamfile for boost, which I can send if needed. Thanks for any assistance, -Brian ****** pgi 7.1 compile errors ******** "/scratch/SIERRA_TRILINOS/code/TPLs_src/boost/boost/math/special_functions/detail/lanczos_sse2.hpp", line 26: error: identifier "align" is undefined static const ALIGN16 double coeff[26] = { ^ "/scratch/SIERRA_TRILINOS/code/TPLs_src/boost/boost/math/special_functions/detail/lanczos_sse2.hpp", line 26: error: expected a ";" static const ALIGN16 double coeff[26] = { ^ "/scratch/SIERRA_TRILINOS/code/TPLs_src/boost/boost/math/special_functions/detail/lanczos_sse2.hpp", line 54: error: a global-scope declaration may not have this storage class register __m128d vx = _mm_load1_pd(&x); ^ "/scratch/SIERRA_TRILINOS/code/TPLs_src/boost/boost/math/special_functions/detail/lanczos_sse2.hpp", line 54: error: identifier "x" is undefined register __m128d vx = _mm_load1_pd(&x); ^ "/scratch/SIERRA_TRILINOS/code/TPLs_src/boost/boost/math/special_functions/detail/lanczos_sse2.hpp", line 55: error: a global-scope declaration may not have this storage class register __m128d sum_even = _mm_load_pd(coeff); ^ "/scratch/SIERRA_TRILINOS/code/TPLs_src/boost/boost/math/special_functions/detail/lanczos_sse2.hpp", line 55: error: identifier "coeff" is undefined register __m128d sum_even = _mm_load_pd(coeff); ^ "/scratch/SIERRA_TRILINOS/code/TPLs_src/boost/boost/math/special_functions/detail/lanczos_sse2.hpp", line 56: error: a global-scope declaration may not have this storage class register __m128d sum_odd = _mm_load_pd(coeff+2); ^ "/scratch/SIERRA_TRILINOS/code/TPLs_src/boost/boost/math/special_functions/detail/lanczos_sse2.hpp", line 57: error: a global-scope declaration may not have this storage class register __m128d nc_odd, nc_even; ^ "/scratch/SIERRA_TRILINOS/code/TPLs_src/boost/boost/math/special_functions/detail/lanczos_sse2.hpp", line 57: error: a global-scope declaration may not have this storage class register __m128d nc_odd, nc_even; ^

[serialization] boost::serialization adds huge amounts of exports to resultant Windows PE file
by Chris Yuen 04 Oct '10

04 Oct '10

Hey guys, I am using boost::serialization from 1.44.0. One thing that I noticed is that linking statically to the serialization libs will add several hundred exports in the final exe file that I get. Using `dumpbin /exports my_program.exe` Here's a brief illustration: Let's say we have a typical Hello World program (code example at the end of this message) that uses `iostream`. Here's what we get when we run `dumpbin /exports my_program.exe`. Dump of file my_program.exe File Type: EXECUTABLE IMAGE Summary 4000 .data 2000 .pdata 7000 .rdata 1000 .rsrc 18000 .text However, if we just add 6 lines of code to include boost::serialization (code example at the end of this message), we would get tons of exports. Dump of file my_program.exe File Type: EXECUTABLE IMAGE Section contains the following exports for my_program.exe 00000000 characteristics 4CA376FA time date stamp Thu Sep 30 01:27:22 2010 0.00 version 1 ordinal base 14 number of functions 14 number of names ordinal hint RVA name 1 0 00029480 ??_B?1??get_instance@?$singleton@V?$map@Vtext_oarchive@archive@boost@@@?A0xca82ee40@detail@archive@boost@@@serialization@boost@@CAAEAV?$map@Vtext_oarchive@archive@boost@@@?A0xca82ee40@detail@archive@3@XZ@51 = ??_B?1??get_instance@?$singleton@V?$map@Vtext_oarchive@archive@boost@@@?A0xca82ee40@detail@archive@boost@@@serialization@boost@@CAAEAV?$map@Vtext_oarchive@archive@boost@@@?A0xca82ee40@detail@archive@3@XZ@51 (`private: static class boost::archive::detail::`anonymous namespace'::map<class boost::archive::text_oarchive> & __cdecl boost::serialization::singleton<class boost::archive::detail::`anonymous namespace'::map<class boost::archive::text_oarchive> >::get_instance(void)'::`2'::`local static guard'{2}') 2 1 000294B0 ??_B?1??get_instance@?$singleton@V?$multiset@PEBVextended_type_info@serialization@boost@@Ukey_compare@detail@23@V?$allocator@PEBVextended_type_info@serialization@boost@@@std@@@std@@@serialization@boost@@CAAEAV?$multiset@PEBVextended_type_info@serialization@boost@@Ukey_compare@detail@23@V?$allocator@PEBVextended_type_info@serialization@boost@@@std@@@std@@XZ@51 = ??_B?1??get_instance@?$singleton@V?$multiset@PEBVextended_type_info@serialization@boost@@Ukey_compare@detail@23@V?$allocator@PEBVextended_type_info@serialization@boost@@@std@@@std@@@serialization@boost@@CAAEAV?$multi ...elided This is indeed very strange since compiling a `exe` file shouldn't get me any of these "exports" at all. Anyone has an idea what's going wrong? I am using MSVS2005 Release|x64. I compiled boost with `bjam threading=multi link=static runtime-link=static toolset=msvc-8.0`. Thank you for guidance in advance! Best regards, Chris Yuen // Source code to my_program.exe #include <iostream> #include <sstream> // Uncommenting the following block would introduce tons of // exports in the final exe.

Boost Logos
by Ruediger Berlich 04 Oct '10

04 Oct '10

Dear all, I remember that there was a discussion a while ago about logos. Among the proposals was a logo of the type "This code uses Boost". I'd like to acknowledge the great work of the Boost library authors and would thus like to add the logo to the manual of our software. Therefore: I cannot find any "official" logos on the Boost web page that would allow me to do this. What has become of this effort ? Best Regards, Ruediger

Boost Lexer
by Jerry Jeremiah 04 Oct '10

04 Oct '10

At http://www.boost.org/community/review_schedule.html there is a link for the yet to be reviewed Boost Lexer library. It points to http://boost- consulting.com/vault/index.php? action=downloadfile&filename=boost.lexer.zip&directory=Strings%20-%20Text% 20Processing but the directory it goes to has no file that is obviously the Boost Lexer library. Has it been moved somewhere else? Is there somewhere else I could get it from? Also (unrelated) why isn't Boost 1.44 in the table under "Past Review Results and Milestones"? I would have expected it since the Noost releases prior to that are listed there. And one last question, where can I get a copy of Steven Watanabe's Switch library? On that same page I can see the "accepted" email but I can't figure out where to find the actual library. Thanks very much.

On the review schedule page ( http://www.boost.org/community/review_schedule.html ) there is a link to download the Boost Lexer library: http://boost-consulting.com/vault/index.php? action=downloadfile&filename=boost.lexer.zip&directory=Strings%20-%20Text% 20Processing But when I click it it takes me to a directory in the Boost Vault that doesn't contain anything that is obviously this library. Is there someplace else to get it? Jerry

[spirit][qi] Iteration / string iterator
by alfC 03 Oct '10

can anybody explain to me why this example from the Spirit.Qi manual works http://www.boost.org/doc/libs/1_44_0/libs/spirit/example/qi/complex_number.… and when I try to use the string iterators directly I get a horrific compiler error? Something to do with string iterators being pointers or something? std::string s = "(2, 3)"; // < line added to example bool r = phrase_parse(s.begin(), s.end(), //< only line changed in the example was (first, last) // Begin grammar ( '(' >> double_[ref(rN) = _1] >> -(',' >> double_[ref(iN) = _1]) >> ')' | double_[ref(rN) = _1] ), // End grammar space); Thank you Alfredo error message below:

[Boost.Units] radians and degrees
by Diederick C. Niehorster 03 Oct '10

03 Oct '10

Dear List, I use VS2010. I have just ventured into Boost.Units as me and my colleagues frequently make errors in our code by mixing up degrees and radians (function takes one but we supply it the other). In some cases a degree representation makes sense, in other the radian representation. Basically, I want to use radian and degree quantities and use implicit conversions to freely interchange between the two (say a user supplies degrees to a function whose declaration asks for radians, or vice versa, things should simply be converted on the fly so that the function has the input it expects and its output is not wrong). I have no need for the SI system or anything else. I am however having some trouble understanding something that must be rather basic. Consider the following code: ---- #include <boost/units/quantity.hpp> #include <boost/units/systems/si/plane_angle.hpp> #include <boost/units/systems/angle/degrees.hpp> int main(int argc, char* argv[]) { boost::units::quantity<boost::units::si::plane_angle> r(.38*boost::units::si::radian); boost::units::quantity<boost::units::si::plane_angle> d(6*boost::units::degree::degree); r = 2.*d; d = 6*boost::units::degree::degree; d = 2.*r; return 1; } ---- The declaration of d works just fine, but assigning exactly the same to d two lines below does not, giving me a compilation error where the crux is "error C2338: (is_implicitly_convertible<Unit2,unit_type>::value == true)". I am thinking that the problem here is that boost::units::degree::degree is not part of the SI system, but of the system defined in boost/units/systems/angle/degrees.hpp. However, why does the declaration initialization two lines above work fine? In any case, for my usage case, should I simply build a minimal system with one dimension, plane_angle, define radian (most stuff does happen in radian, so guess it would cut down on conversions) as the base unit and supply degree as well? How would I then supply degree? All the examples define other units (such as feet instead of meters) in seperate systems using make_system, wouldn't that lead to the problems I observe above? Maybe a very stupid question, but I haven't quite wrapped my head around this: how do I then represent a value in degrees, or is this irrelevant? Any pointers much appreciated! Looking forward to understanding this better. Best and thanks! Dee

[asio] Howto bind *client* to a specific port?
by for-gmane 02 Oct '10

A NewbieQ: From a client app I want to connect to a server app on a remote host (say port 6666). A requirement is that the client shall be bound to a defined port (say port 5555). How to do this in asio? Does the client need to use an acceptor? (ok, this maybe sounds non-sensical, but who knows... :-)
