[lexical_cast] broken for std::vector<char> since last updates
Hi, the last patches to lexical_cast broke some of my code which uses lexical_cast to parse values from std::vector<char> Something as simple as std::vector<char> buffer; return boost::lexical_cast<int>(&buffer[0]); fails with BOOST_ROOT/boost/lexical_cast.hpp:1091:43: error: no matching constructor for initialization of 'std::basic_ostream<char>' std::basic_ostream<CharT> stream(&stringbuffer); ^ ~~~~~~~~~~~~~ this is the start of the clang diagnostic. Both gcc (Ubuntu 4.6.0-3~ppa1) 4.6.1 20110409 (prerelease) and clang version 3.0 (trunk 135897) output contained in attached testcase. Btw. are there any lexical tests in Boost?

Hi,
the last patches to lexical_cast broke some of my code which uses lexical_cast to parse values from std::vector<char>
Something as simple as
std::vector<char> buffer; return boost::lexical_cast<int>(&buffer[0]);
fails with
BOOST_ROOT/boost/lexical_cast.hpp:1091:43: error: no matching constructor for initialization of 'std::basic_ostream<char>' std::basic_ostream<CharT> stream(&stringbuffer); ^ ~~~~~~~~~~~~~ this is the start of the clang diagnostic.
Both gcc (Ubuntu 4.6.0-3~ppa1) 4.6.1 20110409 (prerelease) and clang version 3.0 (trunk 135897)
output contained in attached testcase.
Btw. are there any lexical tests in Boost?
Some tests of the recently added non_finite_num facet and C99 NaN and inf handling from Johna Rade are in http://svn.boost.org/svn/boost/trunk/libs/math/example/lexical_cast_nonfinit... http://svn.boost.org/svn/boost/trunk/libs/math/test/test_lexical_cast.cpp and these pass on main platforms in trunk. It *might* be fallout from the changes made to support NaN and infinities? But the current maintainer Antony Polukhin is the man you need. Paul --- Paul A.

Okay. I was looking for the canonical "libs/lexical_cast/test" directory. Should have invoked "find"...
It might be fallout from the changes made to support NaN and infinities?
And "minor bugfixes". Yes, definetely.
But the current maintainer Antony Polukhin is the man you need.
Yes, found ticket #5732 and commented there, too. Thanks for the pointers to the tests. Yours, Jürgen -- * Dipl.-Math. Jürgen Hunold ! Ingenieurgesellschaft für * voice: ++49 511 262926 57 !

Fixed in revision 73357. Added some tests for described case. Great thanks for testing and reporting bugs! Best regards, Antony Polukhin

Thanks. Works again ;-))

You are welcome. I know why I compile our sources against trunk. This helps catching bugs while they are fresh. Yours, Jürgen -- * Dipl.-Math. Jürgen Hunold !
