I believe this is a compiler error and the only way I'm aware of to work around it is to perform this computation:
const bool no_padding = bits_per_block == CHAR_BIT * sizeof(Block); const mode m = table_width >= CHAR_BIT && no_padding ? access_by_bytes : access_by_blocks;
Sorry for asking again, but I tried CW9.2 evaluation version and it *doesn't* give errors. Since I'm worried that introducing two new class templates can trigger warnings/errors with other compilers, Would it be ok to write e.g.
const bool no_padding = bits_per_block == CHAR_BIT * sizeof(Block); const bool table_is_large_enough = table_width >= CHAR_BIT;
return do_count( m_bits.begin(), num_blocks(), Block(0), (mode_to_type< (no_padding && table_is_large_enough?) access_by_bytes : access_by_blocks
*) 0 );
?
Yes, I believe this will work.
using class static const members instead of function-locale const variables.
### mwcc Compiler: # 1419: const ctype<Ch> & fac = BOOST_USE_FACET(ctype<Ch>, os.getloc()); # Error: ^^^^^ # undefined identifier 'ctype' # (included from: # dynamic_bitset.hpp:17 # bitset_test.hpp:27 # dyn_bitset_unit_tests1.cpp:12)
Looks like <locale> is not getting included.
This one is odd. I see that the command line used for regression testing includes "-runtime dmd", and our metrowerks config file has
// locale support is disabled when linking with the dynamic runtime # ifdef _MSL_NO_LOCALE # define BOOST_NO_STD_LOCALE # endif
Since I test for BOOST_NO_STD_LOCALE before #including it may well be that <locale> is not getting included :) But why everything works with CW 9.2 instead? Can you please confirm that _MSL_NO_LOCALE is defined for version 8.3 and not for 9.2?
That is correct, for building/using the std::lib in a DLL configuration. When linking statically to the std::lib, _MSL_NO_LOCALE is not defined for either release. When _MSL_NO_LOCALE is defined, that means that facets (such as ctype) don't exist as well. In a nutshell, chapter 22 disappears, along with everything that appears in the <locale> synopsis. -Howard
