[crc] Current status of this library

Hi all, I have a compile error using the Boost 1.63.0 CRC library with the g++ v6.3 compiler with the following usage: #include <boost/crc.hpp> extern "C" { short crc12 (unsigned char const * data, int length); bool crc12_check (unsigned char const * data, int length); } // assumes CRC is last 16 bits of the data and is set to zero // caller should assign the returned CRC into the message in big endian byte order short crc12 (unsigned char const * data, int length) { return boost::augmented_crc<12, 0xc06> (data, length); } bool crc12_check (unsigned char const * data, int length) { return !boost::augmented_crc<12, 0xc06> (data, length); } The error I get with g++ v6.3 is: In file included from /home/bill/wsjtx-prefix/src/boost/boost/config.hpp:61:0, from /home/bill/wsjtx-prefix/src/boost/boost/crc.hpp:12, from /home/bill/wsjtx-prefix/src/lib/crc12.cpp:1: /home/bill/wsjtx-prefix/src/boost/boost/crc.hpp: In instantiation of ‘const least boost::detail::mask_uint_t<12ul>::sig_bits’: /home/bill/wsjtx-prefix/src/boost/boost/crc.hpp:356:9: required from ‘const fast boost::detail::mask_uint_t<12ul>::sig_bits_fast’ /home/bill/wsjtx-prefix/src/boost/boost/crc.hpp:1075:16: required from ‘typename boost::uint_t<Bits>::fast boost::augmented_crc(const void*, std::size_t, typename boost::uint_t<Bits>::fast) [with long unsigned int Bits = 12ul; typename boost::uint_t<Bits>::fast TruncPoly = 3078u; typename boost::uint_t<Bits>::fast = short unsigned int; std::size_t = long unsigned int]’ /home/bill/wsjtx-prefix/src/boost/boost/crc.hpp:1092:41: required from ‘typename boost::uint_t<Bits>::fast boost::augmented_crc(const void*, std::size_t) [with long unsigned int Bits = 12ul; typename boost::uint_t<Bits>::fast TruncPoly = 3078u; typename boost::uint_t<Bits>::fast = short unsigned int; std::size_t = long unsigned int]’ /home/bill/wsjtx-prefix/src/lib/crc12.cpp:14:57: required from here /home/bill/wsjtx-prefix/src/boost/boost/crc.hpp:350:69: warning: left shift of negative value [-Wshift-negative-value] BOOST_STATIC_CONSTANT( least, sig_bits = (~( ~(least( 0u )) << Bits )) ); ~~~~~~~~~~~~~~~~~^~~~~~~~~ /home/bill/wsjtx-prefix/src/boost/boost/crc.hpp:350:69: error: left operand of shift expression ‘(-1 << 12ul)’ is negative [-fpermissive] I note that the develop branch of the CRC library has many changes since Boost 1.63.0 but none are in Boost 1.64.0-beta1. So far I have only tried the new library (devlop branch) with my code and it compiles ok but I need to test it further. Does anyone know why the latest CRC library is not in 1.64 and also does anyone know if the develop branch code is ok and usable by substitution into a 1.63 Boost? Regards Bill Somerville.

Which is strange because the NDK documentation says to use the minimum supported API you intend to use. Which is 15 for me. But just grepping the NDK source directories, I see that certain files/symbols are only defined starting at API 21. I think a lot of the C library headers are provided by the target API directory, and they change it with each version. I'll try 21 and see if I get different results, and hopefully it won't break when running on Android Ice Cream Sandwich (API 15)

I took your advice and compared a real build that worked using CMake (using a simple test cpp file) and what I got from b2. Here is the command line used to build the sample app using CMake.

Note I also passed the -H option, so I could see the include searches performed by clang as it was building boost. The output is long, but I've included it below.

Compare boost::system::error_category
by Christopher Pisz 27 Mar '17

27 Mar '17

The following comparison fails for an error whom outputs "asio.misc" for errorCode.category().name() and "end of file" for errorCode.message() If it claims to be in category asio.misc, then why does the if condition of (errorCode.category() == boost::asio::error::misc_category ) evaluate to false? Googling says that a boost::system::error_code can have the same value in more than one category, so I assume that in order to get the proper message and meaning we must compare boost::system::error_category as well as boost::system::error_code::value. How do we properly compare the category if this fails to work? Code in question: //-------------------------------------------------------------------------------------------------- std::string ClientSocketASIO::ErrorCodeToString(const boost::system::error_code & errorCode) { std::ostringstream debugMsg; debugMsg << " Error Category: " << errorCode.category().name() << ". " << " Error Message: " << errorCode.message() << ". "; if( errorCode.category() == boost::asio::error::misc_category ) { switch (errorCode.value()) { case boost::asio::error::eof: debugMsg << ". Server has disconnected."; break; case boost::asio::error::connection_refused: debugMsg << ". Connection Refused"; break; default: debugMsg << ". Unknown Error."; break; } } else { debugMsg << ". Unknown Error category."; } return debugMsg.str(); } -- View this message in context: http://boost.2283326.n4.nabble.com/Compare-boost-system-error-category-tp46… Sent from the Boost - Users mailing list archive at Nabble.com.

Compile error with low_bits_mask_t
by Michael Kaes 27 Mar '17

27 Mar '17

Hi, I discovered a compile issue when using boosts integer_mask. The following simple program compiles fine with clang but fails with gcc. #include <iostream> #include <boost/integer.hpp> #include <boost/integer/integer_mask.hpp> int main() { typedef boost::low_bits_mask_t<2> mask_type_t; std::cout << mask_type_t::sig_bits << std::endl; return 0; } I took both clang and gcc from the svn trunk and boost in version 1.63. I did not have the time yet to dig through the boost implementation but I could not find anything in the issue tracker. So is this a compiler error of gcc or is this a bug in boost. I was able to find a stackoverflow question: http://stackoverflow.com/questions/40291949/boostinteger-mask-gcc-compiler-… And the answer sounds reasonable to me that this is a bug in boost. Can anyone confirm this? And why does clang accept this? Thanks, Michael

License questions

I am making a confidential commercial closed-source program, and Boost's libraries seem useful for me. I can't tell if the Boost license allows me to include it in closed-source. Would anybody know?

That appears to be the definition of what license they wanted, not the actual license.
