[Bug c++/43915] Compiler flags error: error: invalid initialization of reference of type 'boost::thread' from expression of type 'boost::thread'
--- Comment #11 from mlrus at mac dot com 2010-05-14 13:25 --- The following shows how to patch, compile and use boost 1.43.0 with g++ -std=c++0x. At issue are the rvalue references and typecasts in the boost threading libraries. Simply tell Boost not to use its rvalue reference code when it gets compiled, even with option std=c++0x is set. Here's how: 1. Modify operatingSystem.jam, to compile with the -std=c+0x option. Also, remove the -no-cpp-precomp option if it is not supported by your compiler. For OS X I changed tools/build/v2/tools/darwin.jam at line 483 like this # Misc options. #flags darwin.compile OPTIONS : -no-cpp-precomp -gdwarf-2 ; flags darwin.compile OPTIONS : -std=c++0x -gdwarf-2 ; 2. Modify gcc.hpp to disable the conditional compilation of rvalue references (temporarily, until that part of the code works with g++) diff gcc.hpp.orig gcc.hpp 124c124,125 # define BOOST_HAS_RVALUE_REFS // # define BOOST_HAS_RVALUE_REFS # define BOOST_NO_RVALUE_REFERENCES In this manner you can compile and use Boost 1.43 fine gcc 4.5 or earlier, and still build your software to use the c++0x features supported by the gnu copmiler option -std=c++0x. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43915

This might be an issue with boost. There was a change with respect to rvalue references; lvalues cannot bind to rvalue references. The C++0x standard is changing still so this was a change with the standard between the releases of 4.4 and 4.5. -- pinskia at gcc dot gnu dot org changed: What|Removed |Added Status|UNCONFIRMED |WAITING http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43915 --- You are receiving this mail because: --- You are on the CC list for the bug, or are watching someone who is.
